        To be used for tests when we need to wait for an async operation to complete. Pass a timeout, and a lambda for checking if the operation is complete.
        Parameters:
        timeout - amount of time to wait
        timeoutUnit - TimeUnit for the {@param timeout}
        condition - A BooleanSupplier which should execute the non-deterministic action and return true if it is successful, false otherwise.
        Throws:
        java.lang.AssertionError

                                             throws java.lang.AssertionError
        To be used for tests when we need to wait for an async operation to complete. Pass a timeout, and a labmda for checking if the operation is complete. There is an issue within Mockito where it emits VerifyError instead of ArgumentsAreDifferent Exception. Check out "ExceptionFactory#JunitArgsAreDifferent" for details. The workaround here is to catch both assert and verify error. TODO: find a better way resolve it
        Parameters:
        timeout - amount of time to wait
        timeoutUnit - TimeUnit for the {@param timeout}
        assertion - A TestUtils.NonDeterministicAssertion which should simply execute without exception if it is successful, or throw an AssertionError otherwise.
        Throws:
        java.lang.AssertionError - throws the exception thrown by the TestUtils.NonDeterministicAssertion if the maximum wait time has been exceeded.
