Reload external configuration in cache after specified time in Spring - spring

The requirement is
Load external XML configuration file.
Changes in configuration should be reflected without server restart
Configuration should be loaded in cache and get refreshed in the cache after fix interval that will be configured in the external property file.
I tried the below code using FileChangedReloadingStrategy
public class MyApplicationProperties {
private static final Logger log = LoggerFactory.getLogger(MyApplicationProperties.class);
private static XMLConfiguration configuration = null;
static {
try {
configuration = new XMLConfiguration("MonitoringConfig.xml");
final FileChangedReloadingStrategy strategy = new FileChangedReloadingStrategy();
strategy.setRefreshDelay(60000);
log.debug("Loading Property");
configuration.setReloadingStrategy(strategy);
} catch (ConfigurationException e) {
log.error(e.getMessage());
}
}
public static synchronized String getProperty(final String key) {
log.debug("UserId: {}", configuration.getString("UserId"));
log.debug("UserName: {} ", configuration.getString("TriggerEvent.UserName"));
return "DONE";
}
}
above code is working fine and detecting the changes in the file, now the question is how to implement point 3 i.e. caching?

How to run Quarkus programatically in Test mode

I am trying to run acceptance tests with concordion fixtures in a quarkus project. Concordion does not work with Junit5 so I am using its original #Run(ConcordionRunner.class).
I am creating a superclass to start my quarkus application before tests like that:
#RunWith(ConcordionRunner.class)
public abstract class AbstractFixture {
public static RunningQuarkusApplication application;
protected static RequestSpecification server;
protected AbstractFixture() {
setUp();
}
public void setUp() {
if(application == null) {
startApplication();
server = new RequestSpecBuilder()
.setPort(8081)
.setContentType(ContentType.JSON)
.build();
}
}
private void startApplication() {
try {
PathsCollection.Builder rootBuilder = PathsCollection.builder();
Path testClassLocation = PathTestHelper.getTestClassesLocation(getClass());
rootBuilder.add(testClassLocation);
final Path appClassLocation = PathTestHelper.getAppClassLocationForTestLocation(
testClassLocation.toString());
rootBuilder.add(appClassLocation);
application = QuarkusBootstrap.builder()
.setIsolateDeployment(false)
.setMode(QuarkusBootstrap.Mode.TEST)
.setProjectRoot(Paths.get("").normalize().toAbsolutePath())
.setApplicationRoot(rootBuilder.build())
.build()
.bootstrap()
.createAugmentor()
.createInitialRuntimeApplication()
.run();
} catch (BindException e) {
e.printStackTrace();
System.out.println("Address already in use - which is fine!");
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
The code above is working but I can't change the default port 8081 to any other.
If I print the config property in my Test class like below, it prints the port correctly, but quarkus is not running on it:
public class HelloFixture extends AbstractFixture {
public String getGreeting() {
Response response = given(server).when().get("/hello");
System.out.println("Config[port]: " + application.getConfigValue("quarkus.http.port", String.class));
return response.asString();
}
}
How can I specify the configuration file or property programatically before run?
I found the answer. At first, I was referencing the wrong property "quarkus.http.port" instead of "quarkus.http.test-port".
Despite that, I found the way to override properties before run:
...
StartupAction action = QuarkusBootstrap.builder()
.setIsolateDeployment(false)
.setMode(QuarkusBootstrap.Mode.TEST)
.setProjectRoot(Paths.get("").normalize().toAbsolutePath())
.setApplicationRoot(rootBuilder.build())
.build()
.bootstrap()
.createAugmentor()
.createInitialRuntimeApplication();
action.overrideConfig(getConfigOverride());
application = action.run();
...
private Map<String, String> getConfigOverride() {
Map<String, String> config = new HashMap<>();
config.put("quarkus.http.test-port", "18082");
return config;
}

Micrometer - WebMvcTagsContributor not adding custom tags

I'm trying to add custom tags - the path variables and their values from each request - to each metric micrometer generates. I'm using spring-boot with java 16.
From my research i've found that creating a bean of type WebMvcTagsContributor alows me to do just that.
This is the code
public class CustomWebMvcTagsContributor implements WebMvcTagsContributor {
private static int PRINT_ERROR_COUNTER = 0;
#Override
public Iterable<Tag> getTags(HttpServletRequest request, HttpServletResponse response,
Object handler,
Throwable exception) {
return Tags.of(getAllTags(request));
}
private static List<Tag> getAllTags(HttpServletRequest request) {
Object attributesMapObject = request.getAttribute(View.PATH_VARIABLES);
if (isNull(attributesMapObject)) {
attributesMapObject = request.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);
if (isNull(attributesMapObject)) {
attributesMapObject = extractPathVariablesFromURI(request);
}
}
if (nonNull(attributesMapObject)) {
return getPathVariablesTags(attributesMapObject);
}
return List.of();
}
private static Object extractPathVariablesFromURI(HttpServletRequest request) {
Long currentUserId = SecurityUtils.getCurrentUserId().orElse(null);
try {
URI uri = new URI(request.getRequestURI());
String path = uri.getPath(); //get the path
UriTemplate uriTemplate = new UriTemplate((String) request.getAttribute(
HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE)); //create template
return uriTemplate.match(path); //extract values form template
} catch (Exception e) {
log.warn("[Error on 3rd attempt]", e);
}
return null;
}
private static List<Tag> getPathVariablesTags(Object attributesMapObject) {
try {
Long currentUserId = SecurityUtils.getCurrentUserId().orElse(null);
if (nonNull(attributesMapObject)) {
var attributesMap = (Map<String, Object>) attributesMapObject;
List<Tag> tags = attributesMap.entrySet().stream()
.map(stringObjectEntry -> Tag.of(stringObjectEntry.getKey(),
String.valueOf(stringObjectEntry.getValue())))
.toList();
log.warn("[CustomTags] [{}]", CommonUtils.toJson(tags));
return tags;
}
} catch (Exception e) {
if (PRINT_ERROR_COUNTER < 5) {
log.error("[Error while getting attributes map object]", e);
PRINT_ERROR_COUNTER++;
}
}
return List.of();
}
#Override
public Iterable<Tag> getLongRequestTags(HttpServletRequest request, Object handler) {
return null;
}
}
#Bean
public WebMvcTagsContributor webMvcTagsContributor() {
return new CustomWebMvcTagsContributor();
}
In order to test this, i've created a small spring boot app, added an endpoint to it. It works just fine.
The problem is when I add this code to the production app.
The metrics generates are the default ones and i can't figure out why.
What can I check to see why the tags are not added?
local test project
http_server_requests_seconds_count {exception="None", method="GET",id="123",outcome="Success",status="200",test="test",uri="/test/{id}/compute/{test}",)1.0
in prod - different (& bigger) app
http_server_requests_seconds_count {exception="None", method="GET",outcome="Success",status="200",uri="/api/{something}/test",)1.0
What i've tried and didn't work
Created a bean that implemented WebMvcTagsProvider - this one had an odd behaviour - it wasn't creating metrics for endpoints that had path variables in the path - though in my local test project it worked as expected
I added that log there in order to see what the extra tags are but doesn't seem to reach there as i don't see anything in the logs - i know, you might say that the current user id stops it, but it's not that.

List Files from Templates Directory in Spring Boot

I would like to generate a blog posts overview. For that I want to read the html files from a folder inside the templates folder in the resources folder where Spring Boot stores its templates.
I tried that but it doesnt return an error but also list no files.
What is the way to go here?
Thanks
#Controller
public class Route {
#Autowired
private ResourceLoader resourceLoader;
#RequestMapping("/")
public String home() throws IOException {
final String path = "templates/blog";
final Resource res = resourceLoader.getResource("templates/blog");
try (final BufferedReader reader = new BufferedReader(new InputStreamReader(res.getInputStream()))) {
reader.lines().forEachOrdered(System.out::println);
}
return "blog/a";
}
}
#Controller
public class Route {
#Value("classpath:templates/blog/*")
private Resource[] resources;
#RequestMapping("/")
public String home() throws IOException {
for (final Resource res : resources) {
System.out.println(res.getFilename());
}
return "blog/a";
}
}
did the trick to me.
You should be able to achieve this using NIO2.
In order for NIO2 to work, it requires the concept of FileSystem, and one can be created from the jar URI. Then this file system can be used with Files/Paths.
The code below contains two branches - the first handles loading the files from inside Jar, the second branch - when the code runs from IDE or via "mvn spring-boot:run".
All streams are being used via try-with-resources so they will be auto-closed.
The find function starts from the top of the file system and recursively searches for html files.
public static void readFile(String location) throws URISyntaxException {
URI uri = Objects.requireNonNull(ReadFromJar.class.getClassLoader().getResource(location)).toURI();
if (uri.getScheme().equals("jar")) { //inside jar
try (FileSystem fs = FileSystems.newFileSystem(uri, Collections.emptyMap())) { //build a new FS that represents the jar's contents
Files.find(fs.getPath("/"), 10, (path, fileAttr) -> // control the search depth (e.g. 10)
fileAttr.isRegularFile() //match only files
&& path.toString().contains("blog") //match only files in paths containing "blog"
&& path.getFileName().toString().matches(".*\\.html")) // match only html files
.forEach(ReadFromJar::printFileContent);
} catch (IOException ex) {
ex.printStackTrace();
}
}
else { //from IDE or spring-boot:run
final Path path = Paths.get(uri);
try (DirectoryStream<Path> dirStream = Files.newDirectoryStream(path)) {
dirStream.forEach(ReadFromJar::printFileContent);
} catch (IOException e) {
e.printStackTrace();
}
}
}
private static void printFileContent(final Path file) {
try {
System.out.println("Full path: " + file.toAbsolutePath().toString());
Files.lines(file).forEach(System.out::println);
} catch (IOException e) {
e.printStackTrace();
}
}

Implementing different destinations in applications on the Tomcat server

Earlier this year I developed an implementation of the SAP JCO CustomDestinationProvider for one of my Spring MVC tomcat applications. In my application, I use this implementation to call a BAPI in my SAP R/3 system to retrieve data.
I am now working on a second Spring MVC tomcat application that I want to have call a BAPI in my SAP R/3 system to retrieve data. It will be a different BAPI that I will be calling, thus it will be different data that I will be retrieving. Since this is a different application calling a different BAPI, I want to use a different SAP system user in my configurations. This new application will be running on the same physical tomcat server as the first application.
My question is should I develop another implementation of the SAP JCO CustomDestinationProvider for this new application or should I somehow reuse the first implementation? If the answer is that I should develop another implementation for this new application, I would expect then that I would develop another implementation for each new Spring MVC tomcat application that I develop that needs to talk to SAP. Is this correct thinking?
If I do a different implementation for this new application of mine, should I be using the same destination name in the code, or should I use a different name?
Below is the code for my first implementation of CustomDestinationDataProvider:
public class CustomDestinationDataProvider {
public class MyDestinationDataProvider implements DestinationDataProvider {
private DestinationDataEventListener eL;
private HashMap<String, Properties> secureDBStorage = new HashMap<String, Properties>();
public Properties getDestinationProperties(String destinationName) {
try {
Properties p = secureDBStorage.get(destinationName);
if(p!=null) {
if(p.isEmpty())
throw new DataProviderException(DataProviderException.Reason.INVALID_CONFIGURATION, "destination configuration is incorrect", null);
return p;
}
return null;
} catch(RuntimeException re) {
throw new DataProviderException(DataProviderException.Reason.INTERNAL_ERROR, re);
}
}
public void setDestinationDataEventListener(DestinationDataEventListener eventListener) {
this.eL = eventListener;
}
public boolean supportsEvents() {
return true;
}
public void changeProperties(String destName, Properties properties) {
synchronized(secureDBStorage) {
if(properties==null) {
if(secureDBStorage.remove(destName)!=null)
eL.deleted(destName);
} else {
secureDBStorage.put(destName, properties);
eL.updated(destName); // create or updated
}
}
}
}
public ArrayList<String> executeSAPCall(Properties connectProperties, ArrayList<String> partnumbers) throws Exception {
String destName = "ABAP_AS";
SAPDAO sapDAO = new SAPDAO();
ArrayList<MaterialBean> searchResults = new ArrayList<MaterialBean>();
MyDestinationDataProvider myProvider = new MyDestinationDataProvider();
boolean destinationDataProviderRegistered = com.sap.conn.jco.ext.Environment.isDestinationDataProviderRegistered();
JCoDestination dest;
try {
if (!destinationDataProviderRegistered) {
com.sap.conn.jco.ext.Environment.registerDestinationDataProvider(myProvider);
myProvider.changeProperties(destName, connectProperties);
}
} catch(IllegalStateException providerAlreadyRegisteredException) {
logger.error("executeSAPCall: providerAlreadyRegisteredException!");
}
try {
dest = JCoDestinationManager.getDestination(destName);
searchResults = sapDAO.searchSAP(dest, partnumbers);
} catch(JCoException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return searchResults;
}
}
If the answer is that I should not need to implement another CustomDestinationDataProvider for my second application, what other considerations do I need to keep in mind?
You can only register one DestinationDataProvider so the one you set must be able to handle both (or more) different connections. In order to do this, you need unique names for each connection, i.e. destName can't be the fixed value ABAP_AS, you need to create one for each connection.
Your current implementation of the provider looks good for me, but your method when calling the RFC is mixing the creation of the connection and the actual RFC-calling too much in my eyes. IMHO you should separate the former into its own method, so you can call it from other parts of your application to e.g. do other things than RFC-calling.
I've figured it out! I discovered two different ways to implement CustomDestinationDataProvider so that I could use multiple destinations.
Something that I did that helped out with both of my different solutions was change out the method in CustomDestinationDataProvider that instantiates the MyDestinationDataProvider inner class so that instead of returning ArrayList, it returns JCoDestination. I changed the name of this method from executeSAPCall to getDestination.
The first way that I discovered that allowed me to use multiple destinations, successfully changing out destinations, was to introduce a class variable for MyDestinationDataProvider so that I could keep my instantiated version. Please note that for this solution, the CustomDestinationDataProvider class is still embedded within my java application code.
I found that this solution only worked for one application. I was not able to use this mechanism in multiple applications on the same tomcat server, but at least I was finally able to successfully switch destinations. Here is the code for CustomDestinationDataProvider.java for this first solution:
public class CustomDestinationDataProvider {
private MyDestinationDataProvider gProvider; // class version of MyDestinationDataProvider
public class MyDestinationDataProvider implements DestinationDataProvider {
private DestinationDataEventListener eL;
private HashMap<String, Properties> secureDBStorage = new HashMap<String, Properties>();
public Properties getDestinationProperties(String destinationName) {
try {
Properties p = secureDBStorage.get(destinationName);
if(p!=null) {
if(p.isEmpty())
throw new DataProviderException(DataProviderException.Reason.INVALID_CONFIGURATION, "destination configuration is incorrect", null);
return p;
}
return null;
} catch(RuntimeException re) {
System.out.println("getDestinationProperties: Exception detected!!! message = " + re.getMessage());
throw new DataProviderException(DataProviderException.Reason.INTERNAL_ERROR, re);
}
}
public void setDestinationDataEventListener(DestinationDataEventListener eventListener) {
this.eL = eventListener;
}
public boolean supportsEvents() {
return true;
}
public void changeProperties(String destName, Properties properties) {
synchronized(secureDBStorage) {
if(properties==null) {
if(secureDBStorage.remove(destName)!=null) {
eL.deleted(destName);
}
} else {
secureDBStorage.put(destName, properties);
eL.updated(destName); // create or updated
}
}
}
}
public JCoDestination getDestination(String destName, Properties connectProperties) {
MyDestinationDataProvider myProvider = new MyDestinationDataProvider();
boolean destinationDataProviderRegistered = com.sap.conn.jco.ext.Environment.isDestinationDataProviderRegistered();
if (!destinationDataProviderRegistered) {
try {
com.sap.conn.jco.ext.Environment.registerDestinationDataProvider(myProvider);
gProvider = myProvider; // save our destination data provider in the class var
} catch(IllegalStateException providerAlreadyRegisteredException) {
throw new Error(providerAlreadyRegisteredException);
}
} else {
myProvider = gProvider; // get the destination data provider from the class var.
}
myProvider.changeProperties(destName, connectProperties);
JCoDestination dest = null;
try {
dest = JCoDestinationManager.getDestination(destName);
} catch(JCoException e) {
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
}
return dest;
}
}
This is the code in my servlet class that I use to instantiate and call CustomDestinationDataProvider within my application code:
CustomDestinationDataProvider cddp = new CustomDestinationDataProvider();
SAPDAO sapDAO = new SAPDAO();
Properties p1 = getProperties("SAPSystem01");
Properties p2 = getProperties("SAPSystem02");
try {
JCoDestination dest = cddp.getDestination("SAP_R3_USERID_01", p1); // establish the first destination
sapDAO.searchEmployees(dest, searchCriteria); // call the first BAPI
dest = cddp.getDestination("SAP_R3_USERID_02", p2); // establish the second destination
sapDAO.searchAvailability(dest); // call the second BAPI
} catch (Exception e) {
e.printStackTrace();
}
Again, this solution only works within one application. If you implement this code directly into more than one application, the first app that calls this code gets the resource and the other one will error out.
The second solution that I came up with allows multiple java applications to use the CustomDestinationDataProvider class at the same time. I broke the CustomDestinationDataProvider class out of my application code and created a separate java spring application for it (not a web application) for the purpose of creating a jar. I then transformed the MyDestinationDataProvider inner class into a singleton. Here's the code for the singleton version of CustomDestinationDataProvider:
public class CustomDestinationDataProvider {
public static class MyDestinationDataProvider implements DestinationDataProvider {
////////////////////////////////////////////////////////////////////
// The following lines convert MyDestinationDataProvider into a singleton. Notice
// that the MyDestinationDataProvider class has now been declared as static.
private static MyDestinationDataProvider myDestinationDataProvider = null;
private MyDestinationDataProvider() {
}
public static MyDestinationDataProvider getInstance() {
if (myDestinationDataProvider == null) {
myDestinationDataProvider = new MyDestinationDataProvider();
}
return myDestinationDataProvider;
}
////////////////////////////////////////////////////////////////////
private DestinationDataEventListener eL;
private HashMap<String, Properties> secureDBStorage = new HashMap<String, Properties>();
public Properties getDestinationProperties(String destinationName) {
try {
Properties p = secureDBStorage.get(destinationName);
if(p!=null) {
if(p.isEmpty())
throw new DataProviderException(DataProviderException.Reason.INVALID_CONFIGURATION, "destination configuration is incorrect", null);
return p;
}
return null;
} catch(RuntimeException re) {
throw new DataProviderException(DataProviderException.Reason.INTERNAL_ERROR, re);
}
}
public void setDestinationDataEventListener(DestinationDataEventListener eventListener) {
this.eL = eventListener;
}
public boolean supportsEvents() {
return true;
}
public void changeProperties(String destName, Properties properties) {
synchronized(secureDBStorage) {
if(properties==null) {
if(secureDBStorage.remove(destName)!=null) {
eL.deleted(destName);
}
} else {
secureDBStorage.put(destName, properties);
eL.updated(destName); // create or updated
}
}
}
}
public JCoDestination getDestination(String destName, Properties connectProperties) throws Exception {
MyDestinationDataProvider myProvider = MyDestinationDataProvider.getInstance();
boolean destinationDataProviderRegistered = com.sap.conn.jco.ext.Environment.isDestinationDataProviderRegistered();
if (!destinationDataProviderRegistered) {
try {
com.sap.conn.jco.ext.Environment.registerDestinationDataProvider(myProvider);
} catch(IllegalStateException providerAlreadyRegisteredException) {
throw new Error(providerAlreadyRegisteredException);
}
}
myProvider.changeProperties(destName, connectProperties);
JCoDestination dest = null;
try {
dest = JCoDestinationManager.getDestination(destName);
} catch(JCoException ex) {
ex.printStackTrace();
throw ex;
} catch (Exception ex) {
ex.printStackTrace();
throw ex;
}
return dest;
}
}
After putting this code into the jar file application and creating the jar file (I call it JCOConnector.jar), I put the jar file on the shared library classpath of my tomcat server and restarted the tomcat server. In my case, this was /opt/tomcat/shared/lib. Check your /opt/tomcat/conf/catalina.properties file for the shared.loader line for the location of your shared library classpath. Mine looks like this:
shared.loader=\
${catalina.home}/shared/lib\*.jar,${catalina.home}/shared/lib
I also put a copy of this jar file in the "C:\Users\userid\Documents\jars" folder on my workstation so that the test application code could see the code in the jar and compile. I then referenced this copy of the jar file in my pom.xml file in both of my test applications:
<dependency>
<groupId>com.mycompany</groupId>
<artifactId>jcoconnector</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>C:\Users\userid\Documents\jars\JCOConnector.jar</systemPath>
</dependency>
After adding this to the pom.xml file, I right clicked on each project, selected Maven -> Update Project..., and I then right clicked again on each project and selected 'Refresh'. Something very important that I learned was to not add a copy of JCOConnector.jar directly to either of my test projects. The reason for this is because I want the code from the jar file in /opt/tomcat/shared/lib/JCOConnector.jar to be used. I then built and deployed each of my test apps to the tomcat server.
The code that calls my JCOConnector.jar shared library in my first test application looks like this:
CustomDestinationDataProvider cddp = new CustomDestinationDataProvider();
JCoDestination dest = null;
SAPDAO sapDAO = new SAPDAO();
Properties p1 = getProperties("SAPSystem01");
try {
dest = cddp.getDestination("SAP_R3_USERID_01", p1);
sapDAO.searchEmployees(dest);
} catch (Exception ex) {
ex.printStackTrace();
}
The code in my second test application that calls my JCOConnector.jar shared library looks like this:
CustomDestinationDataProvider cddp = new CustomDestinationDataProvider();
JCoDestination dest = null;
SAPDAO sapDAO = new SAPDAO();
Properties p2 = getProperties("SAPSystem02");
try {
dest = cddp.getDestination("SAP_R3_USERID_02", p2);
sapDAO.searchAvailability(dest);
} catch (Exception ex) {
ex.printStackTrace();
}
I know that I've left out a lot of the steps involved in first getting the SAP JCO 3 library installed on your workstation and server. I do hope that this helps out at least one other person of getting over the hill of trying to get multiple spring mvc java spplications talking to SAP on the same server.

How to use a single Log4Net instance in mutliple Nunit TestFixtures with SetUpFixture

I'm just getting into the use of Selenium Webdriver and its EventFiring so that I can log any exceptions thrown by the driver to a file or email etc.
I have got Log4Net working and my Unit Tests are running fine with Selenium.
What I am having issues with is having Log4Net create 1 log file, but for multiple test fixtures.
Here are some important classes which I think I need to show you in order to explain my issue.
public class EventLogger : EventFiringWebDriver
{
// Not sure if this is the best place to declare Log4Net
public static readonly ILog Log = LogManager.GetLogger(typeof(EventLogger));
public EventLogger(IWebDriver parentDriver) : base(parentDriver)
{
// To get Log4Net to read the configuration file on what logger to use
// To console , file, email etc
XmlConfigurator.Configure();
if (Log.IsInfoEnabled)
{
Log.Info("Logger started.");
}
}
protected override void OnFindingElement(FindElementEventArgs e)
{
base.OnFindingElement(e);
//TODO:
if (Log.IsInfoEnabled)
{
Log.InfoFormat("OnFindingElement: {0}", e);
}
}
protected override void OnElementClicked(WebElementEventArgs e)
{
base.OnElementClicked(e);
//TODO:
if (Log.IsInfoEnabled)
{
Log.InfoFormat("OnElementClicked: {0}", e.Element.GetAttribute("id"));
}
}
}
Here is my SetupFixture - which I THINK is run every time a new TestFixture class is run.
[SetUpFixture]
public class BaseTest
{
protected static readonly ILog Log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
private FirefoxProfile firefoxProfile;
private IWebDriver driver;
private EventLogger eventLogger;
public IWebDriver StartDriver()
{
Common.WebBrowser = ConfigurationManager.AppSettings["WebBrowser"];
Log.Info("Browser: " + Common.WebBrowser);
switch (Common.WebBrowser)
{
case "firefox":
{
firefoxProfile = new FirefoxProfile { AcceptUntrustedCertificates = true };
driver = new FirefoxDriver(firefoxProfile);
break;
}
case "iexplorer":
{
driver = new InternetExplorerDriver();
break;
}
case "chrome":
{
driver = new ChromeDriver();
break;
}
}
driver.Manage().Timeouts().ImplicitlyWait(Common.DefaultTimeSpan);
// Here is where I start my EventLogger to handle the events from selenium
// web driver, onClick, OnFindingElement etc.
// Is this the best way? Seems a bit messy, lack of structure
return eventLogger = new EventLogger(driver);
}
public EventLogger EventLogger
{
get { return eventLogger; }
}
}
Here is one of the many TestFixtures I have, each one based on a Selenium2 PageObjects
[TestFixture]
public class LoginPageTest : BaseTest
{
private IWebDriver driver;
private LoginPage loginPage;
[SetUp]
public void SetUp()
{
// Where I use the Log from the BaseTest
// protected static readonly ILog Log <-- top of BaseTest
Log.Info("SetUp");
driver = StartDriver();
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(30));
loginPage = new LoginPage();
PageFactory.InitElements(driver, loginPage);
}
[Test]
public void SubmitFormInvalidCredentials()
{
Console.WriteLine("SubmitFormInvalidCredentials");
loginPage.UserName.SendKeys("invalid");
loginPage.Password.SendKeys("invalid");
loginPage.SubmitButton.Click();
IWebElement invalidCredentials = driver.FindElement(By.Id("ctl00_ctl00_ctl00_insideForm_insideForm_ctl02_title"));
Assert.AreEqual("Invalid user name or password", invalidCredentials.Text);
}
}
My Log.txt file is obviously being re-written over and over after each TestFixture is run,
How can I set up my NUnit Testing so that I only run the Log4Net once, so that I can use it in both my EventLogger and TestFixtures?
I have Googled around a lot, maybe its something simple. Do I have some design issues with the structure of my project?
Try out setting explicitly AppendToFile="True" in the log4net configuration for the FileAppender you are using:
<log4net>
<appender name="..." type="log4net.Appender....">
<appendToFile value="true" />
FileAppender.AppendToFile property
Gets or sets a flag that indicates whether the file should be appended
to or overwritten
Regarding [SetupFixture], I believe you are using it in wrong way. It not supposed to mark base class of the each TesFixture by this attribute, this looks messy. You should declare class which considered to be SetupFixture and mark it by [SetupFixture] attribute so it will be called ONCE for all TestFixtures within a given (declaration) namespace.
From NUnit documentation, SetUpFixtureAttribute:
This is the attribute that marks a class that contains the one-time
setup or teardown methods for all the test fixtures under a given
namespace. The class may contain at most one method marked with the
SetUpAttribute and one method marked with the TearDownAttribute
