我的应用中有以下方法,我需要为其编写单元测试用例。
谁能建议我如何测试是否调用了成功 block 或错误 block 。
- (IBAction)loginButtonTappedid)sender
{
void (^SuccessBlock)(id, NSDictionary*) = ^(id response, NSDictionary* headers) {
[self someMethod];
};
void (^ErrorBlock)(id, NSDictionary*, id) = ^(NSError* error, NSDictionary* headers, id response) {
// some code
};
[ServiceClass deleteWebService“http://someurl"
data:nil
withSuccessBlock:SuccessBlock
withErrorBlock:ErrorBlock];
}

您必须使用期望,这是一个相对较新引入的 API。添加它们是为了解决您现在遇到的问题,验证调用了异步方法的回调。
请注意,您还可以设置会影响测试结果的超时(例如,慢速网络连接可能会引发误报,除非您当然要检查慢速连接,尽管有更好的方法来做到这一点) .
- (void)testThatCallbackIsCalled {
// Given
XCTestExpectation *expectation = [self expectationWithDescription"Expecting Callback"];
// When
void (^SuccessBlock)(id, NSDictionary*) = ^(id response, NSDictionary* headers) {
// Then
[self someMethod];
[expectation fulfill]; // This tells the test that your expectation was fulfilled i.e. the callback was called.
};
void (^ErrorBlock)(id, NSDictionary*, id) = ^(NSError* error, NSDictionary* headers, id response) {
// some code
};
[ServiceClass deleteWebService“http://someurl"
data:nil
withSuccessBlock:SuccessBlock
withErrorBlock:ErrorBlock];
};
// Here we set the timeout, play around to find what works best for your case to avoid false positives.
[self waitForExpectationsWithTimeout:2.0 handler:nil];
}
