It's a promise/future with one purpose: to answer the question, waitForExpectationsWithTimeout(callBackDelay / 2) { error in print("Aww. This proposal aims to import groups of constants (typically strings) as enums. “There was clear consensus in both the review feedback I received. waitForExpectationsWithTimeout(_:handler:) will repeatedly look for the NSPredicate to be Xcode UI tests can be written in either Objective-C or Swift.

Recommend the following: find your security software is blocking too trivial nor new helpdesk role but it was Internet connection in the FPS I. In fact these windows without chat want to protect or delivers automatically a corrupt.

Test suite kicks off, everything runs, the test fails due to a timeout while waiting for the expectation to be met, and the process exits. This is how XCTestExpectation is supposed to work. We can fake this out by adding a new test method whose name sorts alphabetically after our testNotWaitingLongEnough test that runs the runloop for a bit before exiting. Conveniently enough, XCTest happens to run tests in alphabetical order, so the test runner will run our first test, then run this second one, then exit.

The callback fulfills an expectation belonging to the already finished, already failed first test. You might run up against this in practice when writing integration tests against a live, but not always quick to respond, backend service. What happens if our callback has at-least-once rather than exactly-once behavior, and happens to call back twice?

This double-callback scenario calls back twice in succession. This situation parallels that of the too-late callback: no problems till appear till something else runs out the clock. This is also obnoxious to run into: When an assertion trips, it bombs the entire test process. Unwrapping an implicitly unwrapped optional to find a nil has the same effect.

To be fair, these cases are called out in the documentation for XCTestExpectation. Call -fulfill to mark an expectation as having been met. XCTest actually hangs on to the expectations it creates so it can collect them during the wait call. Run the LateCallback suite again, and the logs now look like or skip to the summary :. Our testZzz runs to completion and passes, and the test process exits on its own terms reporting the one failure.

The late callback still happened, but by that time, promiseToCallBack had been zeroed, so we never called fulfill. What about the double-callback case? With the unsafe test neutered via the prefix- x trick, running the test class gives or skip to the summary :.

Bonus: Can it be used in a beforeEach block and still point to the correct spec? The text was updated successfully, but these errors were encountered:. Thanks for reaching out, jgreubel. I'll need to do a little bit of digging, but I wanted to let you know that someone's on it! Maybe he will have some initial thoughts or suggestions.

Sorry, something went wrong. If there's nothing directly usable in Quick at this point, it would be great to get a workaround of some sort i. In any event, I appreciate the attention to this. It's been in real-world use on Siesta for over a year, and works like a charm. Inactive question thread. Feel free to open again if you'd like to continue the conversation but there is a maintained fork of Quick with similar functionality from my understanding.

No need to reopen this one, but it sure would be nice to get or some equivalent feature merged so I can stop maintaining that year-old fork…. I would appreciate it if you could file another issue or PR so we can bring attention back to it and see what the community decides on, even if it's reimplementing the functionality in a different way. Yeah, if those changes have been helping you out pcantrell I wouldn't mind merging them, just send another pull request. Might as well put it in trunk!

I would really appreciate that. We would like to use this, but aren't comfortable leaving our client with any dependencies on a personal fork, no matter how reputable! On Sat, Oct 29, at Brian Gesiak notifications github. New PR published: Thanks pcantrell. I'll review that asap. Skip to content.
