Testing on the Swift track

Learn how to test your Swift exercises on Exercism

Running Tests

When you are in the directory for an exercise, you should see two subdirectories:

  • Sources/<Exercise> contains your solution to the exercise
  • Tests/<Exercise>Tests contains the tests to run for the exercise

If you're in the right directory (i.e. the one containing Sources and Tests), you can run the tests for that exercise by running swift test if you are using 5.4 or later:

$ pwd
/Users/johndoe/Code/exercism/swift/hello-world

$ ls
HELP.md  Package.swift  README.md  Sources  Tests

$ swift test

If you are using 5.1 through 5.3 you may have to add the --enable-test-discovery flag:

$ swift test --enable-test-discovery

This will run all of the test files in the Test directory.

For concept exercises, when you got a test passing change the true in the XCTSkipIf to false to enable the next test.

Submitting Your Solution

To upload a solution to Exercism, you have to be in the directory containing the Sources and Tests directories.
