You can automatically in your Mocha projects by integrating with Trunk. This document explains how to configure Mocha 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 .
Before integrating with Trunk, you need to generate Trunk-compatible reports. For Mocha, the easiest approach is to generate XML reports.
First, install the mocha-junit-reporter
package:
You can then generate reports when you run your tests by providing the --reporter
and --reporter-options
options when you run your tests:
You can configure your Mocha runner to use the reporter programmatically as well:
The resulting JUnit XML file will be written to the location specified by the mochaFile
property in reporterOptions
. In the examples above, the results would be at ./junit.xml
.
You need to disable automatic retries if you previously enabled them. Retries compromise the accurate detection of flaky tests.
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 disable retry by omitting the --retries
CLI option and .
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.
