assertThrows

public static void assertThrows(Class<? extends Throwable> expectedThrowable,
                                TestUtils.ThrowingRunnable runnable)

Asserts that runnable throws an exception of type expectedThrowable when executed. 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().

Parameters:

expectedThrowable - the expected type of the exception

runnable - a function that is expected to throw an exception when executed

Since:

4.13

expectThrows

public static <T extends Throwable> T expectThrows(Class<T> expectedThrowable,
                                                   TestUtils.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().

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

Since:

4.13

verifyThrows

public static <T extends Throwable> void verifyThrows(Class<T> expectedThrowable,
                                                      TestUtils.ThrowingRunnable runnable,
                                                      Function<T,Boolean> verify)
                                               throws Exception

Throws:

Exception

waitForCondition

                             throws Exception

Throws:

isExceptionPresentInChain
