iOS Testing: Is there a way to skip tests?

问题

I don't want to execute certain tests if the feature is currently disabled. Is there a way to "skip" a test (and to get appropriate feedback on console)?

Something like this:

func testSomething() {
  if !isEnabled(feature: Feature) {
    skip("Test skipped, feature \(feature.name) is currently disabled.")
  }

  // actual test code with assertions here, but not run if skip above called.
}

You can disable XCTests run by Xcode by right clicking on the test symbol in the editor tray on the left.

You'll get this menu, and you can select the "Disable " option.

Right clicking again will allow you to re-enable. Also, as stated in user @sethf's answer, you'll see entries for currently disabled tests in your .xcscheme file.

As a final note, I'd recommend against disabling a test and committing the disabling code in your xcscheme. Tests are meant to fail, not be silenced because they're inconvenient.

Another possible solution which I found in some article: prefix your skipped tests with something like "skipped_"

Benefits:

XCode will not treat them as tests
You can easily find them using search
You can make them tests again, replacing "skipped_" to ""

I've found a way to do this by modifying my ui test .xcscheme file and adding a section called SkippedTests under TestableReference, then adding individual Test tags with an 'Identifier' attribute with the name of your class and test method. Something like:

<SkippedTests>
       <Test Identifier="ClassName/testMethodName" />
</SkippedTests>

Hope this helps

Unfortunately, there is no build-in test case skipping. The test case either passes or fails.

That means you will have to add that functionality by yourself - you can add a function to XCTestCase (e.g. XCTestCase.skip) via a category that will print the information into console. However, you will have to put a return after that to prevent the other asserts from running.

This is what test schemes are meant to do. You can have different schemes targeting different testing situations or needs. For example, you may want to create a scheme that runs all your tests (full regression scheme), or you may want to select a handful of them to do a quick smoke test on your app when small changes are made. This way, you can select different schemes according to how much testing you need to do. Just go to

Product >> Scheme

There is no test case skipping. You can use if-else block:nested and run/print your desired output.

It's not that universal, but you can override invokeTest in XCTestCase and avoid calling super where necessary. I'm not sure about the appropriate feedback in console though.

For instance the following fragment makes the test run only on iOS Simulator with iPhone 7 Plus/iPad Pro 9.7"/iOS 11.4:

class XXXTests : XCTestCase {

    let supportedModelsAndRuntimeVersions: [(String, String)] = [
        ("iPhone9,2", "11.4"),
        ("iPad6,4", "11.4")
    ]

    override func invokeTest() {
        let environment = ProcessInfo().environment
        guard let model = environment["SIMULATOR_MODEL_IDENTIFIER"], let version = environment["SIMULATOR_RUNTIME_VERSION"] else {
            return
        }
        guard supportedModelsAndRuntimeVersions.contains(where: { $0 == (model, version) }) else {
            return
        }
        super.invokeTest()
    }
