Skip tests at runtime when using SpringJUnit4ClassRunner

Annotate your class (or unit test methods) with @Ignore in Junit 4 and @Disabled in Junit 5 to prevent the annotated class or unit test from being executed.

Ignoring a test class:

@Ignore
public class MyTests {
    @Test
    public void test1() {
       assertTrue(true);
    }
}

Ignoring a single unit test;

public class MyTests {
    @Test
    public void test1() {
         assertTrue(true);
    }

    @Ignore("Takes too long...")
    @Test
    public void longRunningTest() {
        ....
    }

    @Test
    public void test2() {
         assertTrue(true);
    }
}

mvn install -Dmaven.test.skip=true
so you can build your project without test,

mvn -Dtest=TestApp1 test
you can just add the name of your application and you can test it.

I use Spring profiles to do this. In your test, autowire in the Spring Environment:

@Autowired
private Environment environment;

In tests you don't want to run by default, check the active profiles and return immediately if the relevant profile isn't active:

@Test
public void whenSomeCondition_somethingHappensButReallySlowly() throws Exception{
    if (Arrays.stream(environment.getActiveProfiles()).noneMatch(name -> name.equalsIgnoreCase("acceptance"))) {
        return;
    }
    // Real body of your test goes here
}

Now you can run your everyday tests with something like:

> SPRING_PROFILES_ACTIVE=default,test gradlew test

And when you want to run your acceptance tests, something like:

> SPRING_PROFILES_ACTIVE=default,test,acceptance gradlew test

Of course that's just an example command line assuming you use Gradle wrapper to run your tests, and the set of active profiles you use may be different, but the point is you enable / disable the acceptance profile. You might do this in your IDE, your CI test launcher, etc...

Caveats:

1. Your test runner will report the tests as run, instead of ignored, which is misleading.
2. Rather than hard code profile names in individual tests, you probably want a central place where they're all defined... otherwise it's easy to lose track of all the available profiles.
