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"))
}
}
}
class AsynchronousSpec: AsyncSpec {
override class func spec() {
it("runs the test in an async context") {
var ocean: [String] = []
DispatchQueue.main.async {
ocean.append("dolphins")
ocean.append("whales")
}
await expect(ocean).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 QuickSpec
s themselves.
