BREAKING CHANGES

checker-api: The check method of checker plugins now receives a group of mutants and should provide a CheckResult per mutant id.
html reporter: Configuration option htmlReporter.baseDir is deprecated and will be removed in a later version. Please use htmlReporter.fileName instead.
esm config: Exporting a function (using module.exports = function(config) {}) from your stryker.conf.js file is no longer supported. This was already deprecated but now will give an error.
esm: StrykerJS is now a pure ESM. Please read this.
esm: Node 12.20 is now the min version.
esm: Karma v6.3 is now the min supported karma version for @stryker-mutator/karma-runner, since that version added support for async config loading
esm: The @stryker-mutator/jamsine-runner now requires jasmine@3.10 or higher.
esm: The @stryker-mutator/mocha-runner now requires mocha@7.2 or higher.
reload test environment: Test runner plugins must provide TestRunnerCapabilities by implementing the capabilities method.

StrykerJS API

This is the repository for maintaining the API of the StrykerJS mutation testing framework. Plugin creators should depend on this API rather than on the main Stryker repository directly.

Extension use cases

You can extend Stryker in a number of ways.

Create your own Mutator
Create a custom Reporter
Create a TestFramework for a test framework
Create a TestRunner to bridge the gap between your test runner and Stryker
Create a custom way of configuring Stryker by creating an OptionsEditor

All extension points work in the same basic way.

Create a constructor function (or class)
Register the constructor function to the correct Factory.

For more info, please take a look at the Stryker handbook.
