I'm trying to write automated tests using Xamarin UI Test, within certain parts of those tests I need to know which platform they are running on i.e. Android or iOS.
I'm struggling to find a way of doing this, does anyone know of an API to do this or any other such trick?
Your tests class have a constructor like this:
[TestFixture(Platform.Android)]
[TestFixture(Platform.iOS)]
public class Tests
{
IApp app;
Platform platform;
public Tests(Platform platform)
{
this.platform = platform;
}
[SetUp]
public void BeforeEachTest()
{
app = AppInitializer.StartApp(platform);
}
}
Later on, in you test method you could do this:
[Test]
public void MyTest()
{
if (platform == Platform.Android)
{
// Do specific code here.
}
}

I have a reporting application that generates a report on ApplicationReadyEvent. I am trying to write cucumber tests for it but as the application event is fired even before my feature is executed , i am not sure what is the right way to test it. Can i control the event during testing ?
#EventListener(ApplicationReadyEvent.class)
private void generateAccuracyAnalysisReport() throws IOException
{
//some Logic
}
Cucumber Classes :
#SpringBootTest
#CucumberContextConfiguration
#ActiveProfiles("junit")
public class CucumberConfiguration
{
}
#RunWith(Cucumber.class)
#CucumberOptions(plugin = "pretty", features = "src/test/resources/cucumber/features")
public class CucumberFullIntegrationTest
{
}
Step Definition:
public class ReportStepDefs implements En {
public ReportStepDefs() {
When("^System sends an application event to generate report$", () -> {
});
Then("^Report should be generated successfully\\.$", () -> {
});
}
}
If your Cucumber tests involve Spring life-cycle you can not use cucumber-spring. Rather you have to use something like Springs ApplicationContextRunner to, configure, run and verify something about your application as part of each scenario.
// Given
ApplicationContextRunner contextRunner = new ApplicationContextRunner();
// When
contextRunner.withConfiguration(AutoConfigurations.of(...);
// Then
contextRunner.run(context -> assertThat(context).... /* something */ );
// Or assert something external to the application context.
Though it sounds like your application is doing something once and then exits. If so you should be using the CommandLineRunner instead of ApplicationReadyEvent in a web application. This is testable with cucumber-spring.
#RequiredArsConstructor
public class StepDefinitions {
final MyCommandLineRunner commandLineRunner;
#When(....)
public void something() {
commandLineRunner.run("input.txt", "input2.txt");
}
#Then(....)
public void assertSomething() {
// check if report was generated
}
}
I am writing a gradle script that runs all tests before making a build.
test {
filter {
includeTestsMatching "*TestAll*"
includeTestsMatching "*ExtensionValidatorTest*"
........
}
}
I have three tests of different versions(v1,v2,v3).
TestAll.java
package .....v1;//v2 for version 2 and v3 for version 3
#RunWith(Suite.class)
#Suite.SuiteClasses({
A.class,
B.class,
......
})
public class TestAll {
#BeforeClass
public static void setUp() {//connection to database
........
}
#AfterClass
public static void tearDown() {//close database connection
........
}
}
When I run gradle test connection to database is broken after execution of a particular TestAll. I do not want to change the TestAll files of any version as they can be run and tested independently. How can I make gradle run only setUp once(of any version)which establishes connection, then run all the TestAll method in v1,v2 and v3 and finally teardown(of any version) which terminates database connection.
Gradle won't help you with this. There are following methods in Gradle DSL:
test {
beforeSuite{...}
afterSuite{...}
}
However, they execute outside of the test runtime scope and intended for logging. You only can achieve this using a testing framework.
TestNG provides a simple solution - #BeforeSuite and #AfterSuite annotations, that are actually run once before and after the entire suite.
Unfortunately, JUnit doesn't have a built-in solution for that, since test isolation is its core concept. Nevertheless, you still can make your own. You need to encapsulate database-related API into a singleton class:
public class DbContainer() {
private static DbContainer container;
private DbContaner() {}
public DbContainer getInstance() {
if (container == null) {
container = new DbContainer()
}
return container;
}
public void openConnection() {
// ...
}
public void closeConnection() {
// ...
}
// here is your database API methods
}
Then you can share this instance between test methods and classes using #ClassRule annotation:
#ClassRule
public static DbContainer db = DbContainer.getInstance();
#Test
public void someTest() {
db.query(...)
}
Note: provided solution is not thread-safe and doesn't suit the parallel execution. Some additional effort is required to achieve it.
I am new to MVVMCross. I need to get details about whether my android application is running in background or not. To achieve this i have try to implement with IActivityLifecycleCallbacks with MVXApplication.But i get following error "implements Android.Runtime.IJavaObject but does not inherit Java.Lang.Object or Java.Lang.Throwable. This is not supported.". So could anyone suggest me to how to achieve my requirement with MVVM cross.
You can implement that interface in your main application of your Android project and on the OnTrimMemory comparing the level with TrimMemory.UiHidden you can know if the app is in background or not.
public class MainApplication : Application, Application.IActivityLifecycleCallbacks
{
...
public static bool IsApplicationInForeground { get; private set; }
public override void OnCreate()
{
base.OnCreate();
this.RegisterActivityLifecycleCallbacks(this);
}
public override void OnTerminate()
{
base.OnTerminate();
this.UnregisterActivityLifecycleCallbacks(this);
}
public virtual void OnActivityResumed(Activity activity)
{
IsApplicationInForeground = true;
}
public override void OnTrimMemory(TrimMemory level)
{
IsApplicationInForeground &= level != TrimMemory.UiHidden;
base.OnTrimMemory(level);
}
...
}
IDK if it covers all of the cases but I use it in my projects and it works like a charm in the scenarios I've tested

I have written an action filter for a web api. If a method in the api controller throws an unhandled exception, then the filter creates an internal error 500 response.
I need to know how to test the filter?
I have researched extensively but could not create a suitable test. I tried context mocking, a service locator implementation and even an integration test using a test server.
The web api controller looks like this:
namespace Plod.Api.ApiControllers
{
[TypeFilter(typeof(UnhandledErrorFilterAttribute))]
[Route("api/[controller]")]
public class GamesController : BaseApiController
{
public GamesController(IGameService repository,
ILogger<GamesController> logger,
IGameFactory gameFactory
) : base(
repository,
logger,
gameFactory
)
{ }
// ..... controller methods are here
}
}
The complete controller is found here.
The filter is this:
namespace Plod.Api.Filters
{
public class UnhandledErrorFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
if (filterContext.Exception != null)
{
filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
filterContext.ExceptionHandled = true;
}
}
}
}
I even welcome changes to the filter implementation as a possible work around. Any help or ideas would be much appreciated. Thanks.
You probably can't. However, what you can do is spin up a TestServer and then hit it with a HttpClient. This really is an integration test and not a unit test. However, it's the good kind of integration test because it can be run safely in pipelines.
This document explains how to do this:
https://learn.microsoft.com/en-us/aspnet/core/test/integration-tests?view=aspnetcore-3.1
The issue you are going to face is that you will need to mock the underlying services inside your app. If you don't do that, your whole server will spin up and attempt to hit the database etc. Here is an example. This is using Moq. Incidentally I am sharing the ConfigureServices method with unit tests so they use the same object mesh of mocked services. You can still use the full functionality of Moq or NSubstitute to test the back-end (or even front -end).
I can hit my attributes in the test with breakpoint.
private void ConfigureServices(IServiceCollection services)
{
var hostBuilder = new WebHostBuilder();
hostBuilder.UseStartup<TestStartup>();
hostBuilder.ConfigureServices(services =>
{
ConfigureServices(services);
});
_testServer = new TestServer(hostBuilder);
_httpClient = _testServer.CreateClient();
}
private void ConfigureServices(IServiceCollection services)
{
services.AddSingleton(_storageManagerFactory.Object);
services.AddSingleton(_blobReferenceManagerMock.Object);
services.AddSingleton(_ipActivitiesLoggerMocker.Object);
services.AddSingleton(_loggerFactoryMock.Object);
services.AddSingleton(_hashingService);
services.AddSingleton(_settingsServiceMock.Object);
services.AddSingleton(_ipActivitiesManager.Object);
services.AddSingleton(_restClientMock.Object);
_serviceProvider = services.BuildServiceProvider();
}
public class TestStartup
{
public void Configure(
IApplicationBuilder app,
ISettingsService settingsService)
{
app.Configure(settingsService.GetSettings());
}
public IServiceProvider ConfigureServices(IServiceCollection services)
{
var mvc = services.AddMvc(option => option.EnableEndpointRouting = false);
mvc.AddApplicationPart(typeof(BlobController).Assembly);
services.AddSingleton(new Mock<IHttpContextAccessor>().Object);
return services.BuildServiceProvider();
}
}
My JavaFX app's UI freezes after consecutive times of executing webservice calls. Those process calls are asynchronous.
How do I fix this problem? Is there a way to "unfreeze" the UI?
Sorry for the newbie question. But I badly need anyone;'s help
Did you create a thread to execute it? JavaFX is executed on the EDT (event dispatch thread). That is why you experience GUI freeze. Here is what you do
import javafx.async.*
public class MyWebService extends RunnableFuture {
public var webserviceURL:String;
override run(): Void {
// your web service
}
}
public class MyWebServiceTask extends JavaTaskBase {
override create(): RunnableFuture {
return MyWebService {
webserviceURL: "http://...."
};
}
}
def webserviceTask: MyWebServiceTask = MyWebServiceTask { }
webserviceTask.start();
