How do you assert that a certain exception is thrown in JUnit 4 tests?

Question

How can I use JUnit4 idiomatically to test that some code throws an exception?

While I can certainly do something like this:

@Test
public void testFo         


        

Answer 1

BDD Style Solution: JUnit 4 + Catch Exception + AssertJ

import static com.googlecode.catchexception.apis.BDDCatchException.*;

@Test
public void testFooThrowsIndexOutOfBoundsException() {

    when(() -> foo.doStuff());

    then(caughtException()).isInstanceOf(IndexOutOfBoundsException.class);

}
