    • assertThrows

      public static <T extends Throwable> T assertThrows(Class<T> expectedThrowable, ThrowingRunnable runnable)
      Asserts that runnable throws an exception of type expectedThrowable when executed. If it does, the exception object is returned. If it does not throw an exception, an AssertionError is thrown. If it throws the wrong type of exception, an AssertionError is thrown describing the mismatch; the exception that was actually thrown can be obtained by calling Throwable.getCause().

      T - throwable type
      Parameters:
      expectedThrowable - the expected type of the exception
      runnable - a function that is expected to throw an exception when executed
      Returns:
      the exception thrown by runnable
