@flakytests/adapter-vitest

Retry-aware reporter and result adapter for Vitest 3.2 and Node.js 22+. MIT licensed. Standard Vitest JSON does not contain reliable retry evidence.

Declare this package directly because your test configuration imports its reporter:

npm install --save-dev @flakytests/cli @flakytests/adapter-vitest

Merge into your Vitest config:

import { defineConfig } from "vitest/config";

export default defineConfig({
  test: {
    retry: 2,
    reporters: [
      "default",
      [
        "@flakytests/adapter-vitest/reporter",
        { outputFile: "test-results/vitest.json" },
      ],
    ],
  },
});

Configure adapters.vitest.results: test-results/vitest.json in flaky.yml. The VitestAdapter export parses this reporter's versioned output. The reporter preserves retry counts and expected-failure semantics, excludes skipped tests from recovery, and reports global/collection/hook errors as non-quarantinable. Vitest repeats and major versions beyond 3 are not supported.
