Async Test Changes

Quick 7 changes how Async tests are run. Instead of forcing all tests to run in an async context, Quick 7 provides a separate Spec class for Async Tests. Create an AsyncSpec subclass, and all tests inside of that subclass will run in an async context. Tests inside of QuickSpec subclasses will have a similar behavior to what was in Quick 5.

Additionally, Quick 7 changes how the DSL is defined slightly. In Quick 6 and before, the DSL was defined as a series of global functions, available to be called anywhere. In Quick 7, these functions were moved to be static methods on the new SyncDSLUser (which QuickSpec, Behavior, and QuickConfiguration conform to) and AsyncDSLUser (which AsyncSpec and AsyncBehavior conform to) protocols. This allows us to make sure that you are using the correct DSL for the context, and was necessary for this approach.

For example:

class SynchronousSpec: QuickSpec {
    override class func spec() {
        it("runs synchronously, as you'd expect") {
            var ocean: [String] = []
            DispatchQueue.main.async {
                ocean.append("dolphins")
                ocean.append("whales")
            }
            expect(ocean).toEventually(contain("dolphins", "whales"))
        }
    }
}

actor OceanActor<T> {
    var contents: [T] = []
    func append(_ value: T) {
        contents.append(value)
    }
}

class AsynchronousSpec: AsyncSpec {
    override class func spec() {
        it("runs the test in an async context") {
            let ocean = OceanActor<String>()
            Task {
                await ocean.append("dolphins")
                await ocean.append("whales")
            }
            await expect { await ocean.contents }.toEventually(contain("dolphins", "whales"))
        }
    }
}

Unencoded Test Selectors

Furthermore, Quick 7 changes how test selectors are generated for QuickSpec. Now, both AsyncSpec and QuickSpec will use the unencoded test names as the test selectors. Test selectors are now generated by joining the describe/context blocks leading up to the it block with ", ". This makes test names immensely easier to read. For example, with the following spec:

class MySpec: QuickSpec {
    override class func spec() {
        describe("some feature") {
            context("in one case") {
                it("has a behavior") {}
            }

            context("in another case") {
                it("doesn't have the earlier behavior") {}
            }
        }
    }
}

will generate the following test selectors:

• some feature, in one case, has a behavior
• some feature, in another case, doesn't have the earlier behavior

You can disable this change by setting the QUICK_USE_ENCODED_TEST_SELECTOR_NAMES environment variable.

Migrating Suggestions

Quick 7 is not a drop-in migration from either Quick 5 or Quick 6. Quick 5 users will have a slightly easier time upgrading, but due to spec being defined as a class method instead of an instance method, there will still be changes.

Doing a Find & Replace of override func spec with override class func spec will take care of the low-hanging fruit. If you have any test helpers that exist as properties or methods of your QuickSpec subclasses, the you will need to either move them inside of the spec function, or outside to another scope. For Objective-C users, this is, for the most part, a drop-in replacement. You will only need to do anything if you do not use the QuickSpecBegin and QuickSpecEnd macros (in which case: do a find & replace of the regex -(\s*)\(void\)(\s*)spec with +$1(void)$2spec).

For migrating from Quick 6 to Quick 7, it would be easiest to also do a Find & Replace of : QuickSpec to : AsyncSpec, then migrate tests that do not need to run in async contexts to be QuickSpecs themselves.
