Vitest

A guide for generating Trunk-compatible test reports with Vitest

1. Generate JUnit

Update your Vitest config to include the junit reporter:

import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    reporters: [
      ['junit', { outputFile: './junit.xml' }],
    ],
  },
});

2. Output Location

The JUnit report will be written to the outputFile specified in the Vite config. In the example above, the report would be written to ./junit.xml.

Disable Retries

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

If you've enabled retries, you can disable them following the Vitest docs for more accurate results.

Next Step

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