How to check if JUnit test passed

I have written a JUnit test TestClass.test() and in a certain other Java program which sees the test class I want to execute a certain part of the code only if the JUnit test passes. How can I do that? Something like

if(JUnit.passes(TestClass.test)){
    ....
}

>Solution :

You can programmatically run the tests in a JUnit4 test suite and inspect the result with JUnitCore.runClasses:

if (JUnitCore.runClasses(MyTests.class).wasSuccessful()) {
  System.err.println("Tests ran successfully.");
}

Or a single test with:

if (new JUnitCore().run(Request.method(MyTests.class, "myTest")).wasSuccessful()) {
  System.err.println("Tests ran successfully.");
}
