Running JUnit test suite from inside Eclipse

Question

Historically, I've always written my unit tests like this:

public void WidgetTest {
    @Test
    public void test_whatever() {
        // Given...

        // When...

        // Then...
    }
}

This allows me to right-click my test file in Eclipse and Run As >> JUnit, and test that 1 particular test, directly from inside Eclipse. Then, when doing a local (Ant-based) build, I configure a <junit> Ant task to run all of my src/test/java tests at once.

I'm now looking for an in-between solution. That is, a way to run all of my test classes from inside Eclipse, all at once, with the click of a button. A co-worker recommended that Junit has a notion of a "test suite" that I could attach all of my test classes to, but it looks like this test suite is some sort of JAR/tool that I don't want to include in my project.

So I ask: how can I define such a "test suite", consisting of all my test classes, and run all of them in one fell swoop, from inside Eclipse? Thanks in advance.

take a look at this so question http://stackoverflow.com/questions/457276/junit4-test-suites ... after you have create you suite and put all test classes in it you can run it with `right-click` and `run as junit test` — A4L, Feb 26 '13 at 13:31

You can right click a project or package in Eclipse and choose to 'Run As->JUnit Test', to run all tests in that project or package. No need for a test suite unless you only want to run a subset of the tests.

This is for me the cleanest way to do it. TestSuite is not as useful as it was. It may still make sense in some projects (for example Ant + JUNIT 3.X) but useless in some others (maven + JUNIT 4). And from Eclipse, Perception solution will do be ok in any case. – Samuel EUSTACHI Feb 26 '13 at 13:35
Thanks @Perception +1 - please see my comment underneath kolja TM's answer - I have the same question for you! Thanks again! – IAmYourFaja Feb 26 '13 at 13:49
@DirtyMikeAndTheBoys - np, and yes, it effectively scans your resource (project, package etc) for methods annotated with `@Test`, and then runs them with the embedded jUnit plugin. – Perception Feb 26 '13 at 13:53
Would there be a way to do this same thing from within the code? I'm looking to run the entire test suite from the command line, and I figure it'd be easiest to write a separate class which runs the test suite, then call that class. I'm running JUnit 4. – meanderingmoose Jul 24 '14 at 20:54
@meanderingmoose - have you considered using Maven to run your tests? That would save a considerable amount of time and trouble as opposed to coding up your own launcher. – Perception Jul 25 '14 at 13:32
My end goal is to automate the running of the tests so they go off every week, and this is the easiest way I saw to do that. I haven't looked much into Maven, however. – meanderingmoose Jul 25 '14 at 13:39

@meanderingmoose - definitely consider looking into Maven, ideally plugged into a CM tool like Jenkins. You can look at this SO question [http://stackoverflow.com/questions/255370/automating-unit-tests-junit-for-eclipse-plugin-development] for some hints at interacting with the PDE from the command line, but frankly the tech described is old and I really do believe thats more trouble than its worth. – Perception Jul 25 '14 at 14:39

Have you tried to right-click your project and selecting and selecting Run as -> JUnit test? That runs all Unittests in the project.

Thanks @kolja TM (+1) - how does it know which are unit tests? Does it just scan for the `@Test` method? Thanks again! – IAmYourFaja Feb 26 '13 at 13:49
