Infection vs Stryker Dashboard

Infection is a PHP mutation-testing library that shows which changes a test suite fails to detect. It creates mutants using predefined operators, runs tests against changed code, and records killed and escaped mutants, errors, and timeouts. Its Mutation Score Indicator measures the share of generated mutations detected by tests; it also reports Mutation Code Coverage and Covered Code Mutation Score Indicator. Infection supports PHPUnit, PhpSpec, Codeception, and Testo, and runs from the command line at a project root. Teams can run mutated tests in parallel, focus analysis on touched lines or files, and set minimum mutation-score thresholds that fail a build. The homepage describes more than 100 mutators grouped into profiles and allows custom mutators. Optional PHPStan and Mago integrations can help catch escaped mutants involving type violations, dead code, and unreachable paths. Installation options include PHAR, Phive, Composer, Git, and Homebrew. A browser playground supports trying PHP code and tests without installing the tools. Infection is free under the BSD-3-Clause license and requires PHP 8.3 or newer plus Xdebug, phpdbg, or pcov.

Stryker Dashboard is a free, open-source web service for publishing mutation-testing reports and displaying a mutation score badge for repositories. It accepts reports from mutation-testing frameworks that follow the mutation testing report schema, with named language coverage for JavaScript, TypeScript, C#, Scala, and other compatible frameworks. Users enable a repository by signing in with GitHub. Reports can arrive through a Stryker dashboard reporter or by HTTP PUT, authenticated with an API key in STRYKER_DASHBOARD_API_KEY or the X-Api-Key header. Documentation lists full reports, mutation-score reports, and dashboard settings for Stryker, Stryker.NET, and Stryker4s. The API can group multiple reports for one version with an optional module value, useful for monorepos, or accept a score-only report for a badge without storing other report information. Automatic project and version retrieval is documented for Travis, CircleCI, and GitHub Actions across those implementations; Azure DevOps and GitLab CI are supported only for Stryker.NET. The backend currently supports github.com as its Git provider.
