How to run Maven unit test (testng) on Eclipse? - java

I have a Maven project and I have included some unit tests. I can run those unit tests from command line using
mvn test -Dtest=AppTest
It will run the unit test (AppTest class) without any problems. But if I tried to run the test on Eclipse as JUnitTest, I got an error saying
"No Tests found with test runner 'JUnit 3'"
I know the test (AppTest) is not a JUnit test but I didn't see "maven" option if I right clicked on the test class.
Do you know how I could run the tests on Eclipse?

If those are testng tests, then you can download the eclipse plugin for TestNG and right click and run them as test class. Testng plugin here
If you want to run the command line way of maven, you would need the maven plugin for eclipse from here
Then you can right click your project and you should see an option of Run As -> Maven Test. You would need to set relevant arguments in the surefire plugin of pom or use run configuration to specify parameters like you did in -Dtest
I would suggest the testng plugin which would be simpler to just select the class and run the class or a single case or a package even.

Does infinitest for IntelliJ IDEA honor the run tests settings in Gradle?

I have a Gradle project that I would like to use infinitest with. However, while all test pass using the Gradle test runner, many fail in infinitest. Is this because infinitest uses the IntelliJ test runner to run the tests?
I expect this is the case since I get similar results when I try to run tests manually using the IntelliJ test runner.
How can I configure infinitest to use Gradle as the test runner?
Infinitest starts a new JVM to run tests, it gets the project classpath from IntelliJ but does not know it is a Gradle project.
I don't know what the Gradle test runner does differently but it would be great if you could open an issue on the Infinitest bug tracker with the steps to reproduce the problem (ideally with a sample project).
In case the issue is with missing JVM options you can set them using the infinitest.args file

Unit test fails on build from Intellij but passes from terminal

I have a big java project. Using maven to automate the build and manage dependencies and JUnit for the unit testing.
When i'm running mvn clean install from Intellij the build fails because of one unit test that fails.
The test succeeds when ran manually.
Also, executing mvn clean install from the terminal succeeds. (all tests pass)
I'm not sure where to look for the problem here.
Thanks!

IntelliJ IDEA runs full test suite when I try to debug a single unit test

I've inherited a Maven project that includes a large number of unit tests and integration tests. I added a unit test for a change I've made. However, this unit test is failing and so are a number of integration tests (because they rely on a specific environment). I want to debug my unit test (and the method under test), but when I right-click on the test method and choose "debug", IntelliJ IDEA does a "Build" first, and that's the Maven build which tries to execute all tests and integration tests. As a result, the build fails and I can't therefore debug my unit test. How can I get around this?
Intellij has specific configuration for the builds.
The default configuration is the "build" command which will build the project.
You can change this command into a maven command so you will manually skip the tests
to do that click edit configuration and go to the profile configuration you want to change. :
At the very bottom you can see the before launch part :
from there you remove the previous with the ( - ) and you click the ( + ) to add a new one. Scroll down in the list to find the maven goal
once you check it you have to add the manual command there. Note: You dont need to write mvn as its ommited.
An other approach you can follow is to instruct intellij to use maven for all of its actions by delegating everything to maven.
to do that just go to the settings and follow the path :
Build,Execution,Deployment -> Build Tools > Maven > Runner
and check the Delegate IDE build/run actions to Maven.

Running JUnit tests together with Java project

I'm writing code in Intellij and have a JUnit test class included in a project and i understand that running of JUnit should always be done at build time.
Is there a way to first run the JUnit and only if there were no test error run the project itself ? I want them to run together with 1 click (NOT run them seperately/manually).
Also, i would like the above to work even when the project is packed as a .jar file.
How can it be done ?
Thanks !
In Intellij:
Run -> Edit Configurations
Create a JUnit configuration for your tests
Create a Run configuration for your project.
And on "Before Launch": Add -> Run Another Configuration and choose the one created at point 1.
It doesn't matter how your project is packed (jar, ...)
Normally this is done by using a build management tool like: maven, gradle, ant. In this way the build tool will run tests for you and stop if they fail.
With maven, it's just a command: mvn clean package exec:java which will compile code, build project, run tests and execute your code.

Unable to run integration test without compiling (with failsafe)

I currently try to run an integration test with maven failsafe, like described in here: reference link .
For this, I got 3 Modules: datamodule, datamodule2 and testmodule (all covered by a parent pom). testmodule depends on the two other modules. It got an test in src/test/java/ named MyTestIT.java. If I try to run the test with mvn clean test failsafe:integration-test, everything runs fine, but if I only run mvn failsafe:integration-test, it does not work. Does somebody know how it's this way?
If I try to run the test with surefire, for example with mvn test -Dtest=MyTestIT, it says it can't find MyTestIT in datamodule, and I need to set -DfailIfNoTests=false. If I try to run it with mvn test --pl testmodule, it says it can't find the dependencies (this only happens when they are not installed, but I don't want to call install everytime I run a test).
Is there any way of setting this in a pom, either in the parent pom or in the project pom? Or any other way of saying to maven "only run the integration tests, use the right dependencies and do not install everything"?
