How to run entire JUnit Test Suite from within code

Question

In eclipse, with JUnit 4, you can right click a project or package and click Run as JUnit Test, and it will run all the JUnit tests within that grouping. Is there a way to d

Answer 1

You can use packages in junit such as JUnitCore like this:

public static void main(String[] args){
    List tests = new ArrayList();
    tests.add(TestOne.class);
    tests.add(TestTwo.class);

    for (Class test : tests){
        runTests(test);
    }
}

private static void runTests(Class test){
    Result result = JUnitCore.runClasses(test);
    for (Failure failure : result.getFailures()){
        System.out.println(failure.toString());
    }
}

Answer 2

JUnit provides the test Suite. Give that a try.

[...]
public class TestCaseA {
    @Test
    public void testA1() {
        // omitted
    }
}

[...]
public class TestCaseB {
    @Test
    public void testB1() {
        // omitted
  }
}

[...]
@RunWith(value=Suite.class)
@SuiteClasses(value = {TestCaseA.class})
public class TestSuiteA {
}

[...]
@RunWith(value=Suite.class)
@SuiteClasses(value = {TestCaseB.class})
public class TestSuiteB {
}

[...]
@RunWith(value = Suite.class )
@SuiteClasses(value = {TestSuiteA.class, TestSuiteB.class})
public class MasterTestSuite{
}

Use JUnit Suite:

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
// Put your Test Case Class here
@Suite.SuiteClasses({
    JunitTest1.class,
    JunitTest2.class,
    JunitTest3.class
})
public class JunitTestSuite {}

Then create a main method to run it.

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

public class JunitTestSuiteRunner {

public static void main(String[] args) {

    Result result = JUnitCore.runClasses(JunitTestSuite.class);
    for (Failure fail : result.getFailures()) {
        System.out.println(fail.toString());
    }
    if (result.wasSuccessful()) {
        System.out.println("All tests finished successfully...");
    }
}}
