Expect assert when using XCTest

Question

I'm using XCTest in an Objective C project.

In my unit test target function, I use NSAssert to exit when receive an exception.

Even this behavior is expected, the XCTest still treat it as a failure.

Is there a way for XCTest to mark that this unit test is expected to assert?

You use XCAssertThrow macro to test for an arbitrary exception of an expression:

- (void)method {
    @throw [[NSException alloc] initWithName:@"My Exception" reason:nil userInfo:nil];
}

- (void)testThrows {
    XCTAssertThrows([self method], @"The method must throw");
}
