Mocha

A guide for generating Trunk-compatible test reports for Mocha

1. Generate JUnit

Install the mocha-junit-reporter package:

npm install --save-dev mocha-junit-reporter

Configure your Mocha runner to use the JUnit reporter:

var mocha = new Mocha({
    reporter: 'mocha-junit-reporter',
    reporterOptions: {
        mochaFile: './test_results/junit.xml'
    }
});

2. Output Location

The resulting JUnit XML file will be written to the location specified by the mochaFile property in reporterOptions. In the example above, the results would be at ./test_results/junit.xml.

Disable Retries

You need to disable automatic retries if you previously enabled them. Retries compromise the accurate detection of flaky tests.

You can disable retry by omitting the --retries CLI option and removing retries for individual tests.

Next Step

JUnit files generated with Mocha are compatible with Trunk Flaky Tests. See CI Providers for a guide on how to upload test results to Trunk.
