I have managed to get basic unit testing working, however when I add a unit test to project-java I get an error of class not found, looking into it it seems when compiling the testing classes, it dosn't copy the main classes from the project-core, does anyone have any idea how to fix this in maven?
Edit:
To make things more clear, I do know where to place the tests, I have placed in project-java/src/tests However What I mean is it doesnt invlude the clases from project-core/src
A better approach is to add your tests to core/src/test/java and then add a test dependency on playn-java to your core/pom.xml:
<dependency>
<groupId>com.googlecode.playn</groupId>
<artifactId>playn-java</artifactId>
<version>${playn.version}</version>
<scope>test</scope>
</dependency>
You need to store all yours tests not in src/main, but in src/test.
I used JUnit with this guide: Using Junit
I went a different route with this in the end, and actually made a playn-testframework.
a simple playn- project that acted like playn-java etc, but would not render to screen, and had extra callbacks for the tests to use, such as to simulate mouse/keyboard events.

I have some set of test cases configured with TestNG. I developed preconditions in junit5 and this has to be run before the test starts. So I wanted to run in sequence Line Precondition(junit5) and then Testcases.
I am using dependency for Junit5 and TestNG7 in PM.XML. Below is a snapshot of POM.xml htmlunitTest.java is for junit5 and testng.xml for TestNGTest cases. while running build is terminating successfully without execution of any test.
You probably do not want to hear my answer. It is the best I have anyway: Don’t take that route! Don’t couple two frameworks that are not made to work together.
Although there might be a convoluted and hacky way to achieve what you describe, you’re setting yourself up for unnecessary technical complexity. Stick with one framework and use its own means for preconditions or fixing a test order.
I have been provided with a task of creating a Rest Api for a provided situation and I tried creating it in my IDE but when I am trying to copy it in Hackerrank editor it's giving a compilation error for the Annotations that I have added for creating the rest api like #SpringBootApplication and #RestController.
I did it on IDE locally and copied all my classes to the single editor that is provided for running your code but its giving compilation errors on various Annotations used.
Can someone let me know what is the way of creating different classes in the editor if you have multiple classes in your solution with some extra annotations.
You need add this dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
then it will work.
Refer to this hacker rank link to get and idea about where should libraries be input.
My question is really simple, thought I haven't found anything online related to it.
Is the maven-surefire-plugin able to have a dependency excluded but at class level and not at group-id:artifact-id level?
My problem:
I have a web project, related to a plain java project A. This A project contains hundred of classes that do a variety of things (connects to the database, sends web services, calculates stuff, manages the logs, context, sessions, etc...) and the dependency is quite strong. Since all unit testing on the web project will be hard to do without this A project I need to have it as a dependency even for the testing. But of course I cannot use some of the classes in there (mainly the DB connection and the session stuff). So I thought that instead of mocking them (because there are like a few dozens of them and I want to do different things with the functions (like writing to a file that it tried to connect or read the "session" from an xml file)) I can create a A-test project and include the classes I want from this new project and exclude the classes I don't need from the A project.
I know I can copy/paste all the project and then replace the classes I want, but if something changes in project A, I then have to maintain it in A-test (and I am very lazy and don't like to work twice). I thought that maybe I could have some kind of plugin in maven that will copy all the other classes (the one I am not... let say 'overriding'), every time. But it seems a waste of time if I just can tell the plugin which classes to use during the test step.
Thanks for your help!
I am fairly new to writing Maven pom files and JUnit tests. I have following in my pom and it is calling my test scripts as expected.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
</plugin>
It seems JUnit is more popular than sure fire plugin.
1) How is JUnit similar/different from maven sure fire plugin's default behavior (that is working for me from above plugin configuration). I can imagine JUnit having additional API/library; but what do they give me in addition to sure fire plugin
2)what is the easiest way to change my current tests that are running with sure fire plugin to JUnit. I came across following link which sort of implies that adding few lines to pom would be sufficient (?)
http://maven.apache.org/surefire/maven-surefire-plugin/examples/junit.html
3)about previous bullet, what benefits would I have if I convert sure fire plugin tests to JUnit.
Hopefully, I am unambiguous (with my intro background to maven and JUnit)
maven-surefire-plugin is not itself a test framework: it's a Maven plugin that will run tests written with a test framework, either JUnit or TestNG.
I have following in my pom and it is calling my test scripts as expected.
If this is already running your tests then, as Surefire only knows about those two test frameworks, it means you're already using either JUnit or TestNG. You should be able to tell which from the classes you're importing to write your test classes.
(that is working for me from above plugin configuration)
Unless you have a particular requirement there's little reason to move away from the framework you're already using; it doesn't sound like you need to change anything.
As it says right here:
To get started with JUnit, you need to add the required version of JUnit to your project ... This is the only step that is required to get started - you can now create tests in your test source directory (eg, src/test/java).
Your question is confusing and suggests you haven't done any preliminary research yet. When you say "surefire tests" you may mean Pojo tests. If you know what a JUnit test is, it's pretty common sense thing to convert the Pojo tests to JUnit tests. Just put #Test before the Pojo test methods. You may also want to convert assert into the appropriate JUnit assert methods. In summary, just read a JUnit tutorial and the rest will be straight forward.
I have some tests which are dependent on the success and failure of some tests. How can I define dependency as I am using VS2010 Mstest and selenium.
E.g
if test1 is failed then dont run test5, test 6. is this possible.
Unit Tests should always be isolated and completly non dependent on and thing else to run, not make non-fragile.
You could setup catagories with MSTest to seperate them into deferent logical structures.
A great book to find more details is this http://artofunittesting.com
Roy has also does alot of public speaking which is recorded online

Tests shouldn't have dependencies between them.
If you have dependencies, then running them in a different order, or in isolation will cause them to fail sporadically - this can be very confusing for anyone else that is running the tests.
It's much better to define tests that setup their own data and assert something specific. You can use a mocking framework like Rhino Mocks to reduce the dependencies between modules of code by faking (mocking) areas that aren't relevant to your test. This is made much easier if you also use a dependency injection framework like Microsoft Unity as your code will have many more seams where mocking can be applied.
