JUnit套件运行器执行一种方法

Question

I have a test suite that runs all test classes

    @RunWith(Suite.class)
    @Suite.SuiteClasses({TestClass1.class, TestClass1.class})
    }

    public class AllTests extends TestCase {

      public AllTests(String name) {
        super(name);
      }

      public static TestSuite suite() {
        TestSuite suite = new TestSuite("com.myapp.test.AllTests"); 
        return suite;
      }
}

is it possible to implement a custom runner that will run only one method, say "onlyMethodToRun", from every class in the suite?

Answer 1

Yes. Suite.java implements a test runner that examines the classes listed in @Suite.SuiteClasses and uses RunnerBuilder s to find every test method. You should be able to reuse a lot of JUnit's code to implement a Runner that instead only checks for a single method on every class and perhaps uses a subclass of BlockJUnit4ClassRunner that overrides computeTestMethods to only attempt a single method.
