You can automatically in your Swift projects by integrating with Trunk. This document explains how to configure Swift Testing to output JUnit XML reports that can be uploaded to Trunk for analysis.
By the end of this guide, you should achieve the following before proceeding to the to configure your CI provider.
After correctly generating reports following the above steps, you'll be ready to move on to the next steps to .
Trunk detects flaky tests by analyzing test reports automatically uploaded from your CI jobs. You can do this by generating Trunk-compatible XML reports from your test runs.
To output a compatible report, add the --xunit-output argument to your Swift test command:
Due to a with Swift, you must include the --parallel flag for the XML report to output properly.
The test report will be written to the location specified by the --xunit-output argument. In the example above, it would be at ./junit.xml.
You need to disable automatic retries if you previously enabled them. Retries compromise the accurate detection of flaky tests.
Swift Testing doesn't support retries out of the box, but if you implemented retries or imported a package, remember to disable them.
This will not upload anything to Trunk. To improve detection accuracy, you should address all errors and warnings before proceeding to the next steps.
Before modifying your CI jobs to automatically upload test results to Trunk, try uploading a single test run manually.
You make an upload to Trunk using the following command:
Configure your CI to upload test runs to Trunk. Find the guides for your CI framework below:
You can validate your test reports using the . If you don't have it installed already, you can install and run the validate command like this:
You can find your Trunk organization slug and token in the settings or by following these . After your upload, you can verify that Trunk has received and processed it successfully in the Uploads tab. Warnings will be displayed if the report has issues.
