How do I generate code coverage reports in CI?

Generating code coverage reports in Continuous Integration (CI) is essential for maintaining code quality and ensuring your tests are covering as much of your codebase as possible. Here’s a step-by-step guide on how to do it in Swift.

First, you need to make sure you have the necessary tools installed, such as Xcode and a CI tool like Jenkins, GitHub Actions, or Bitrise.

Follow these steps to generate code coverage reports:

  1. Enable code coverage in your Xcode project by going to your scheme settings and checking the "Gather coverage data" option.
  2. Run your tests using the command line to generate coverage data. Use the following command:
    3. xcodebuild test -scheme YourSchemeName -enableCodeCoverage Yes
  3. After running the tests, you can generate the code coverage report using the `xccov` command:
    4. xccov view --report YourProject.xcarchive/Products/Applications/YourApp.app/YourApp.app
  4. To output the report in HTML format, use the `xcpretty` tool along with `xcodebuild`:
    5. xcodebuild test -scheme YourSchemeName -enableCodeCoverage Yes | xcpretty -r html
