What StrykerJS is
StrykerJS is the JavaScript and TypeScript implementation of the Stryker mutation testing tool. Its getting-started guide lists runner plugins for Cucumber, Jasmine, Jest, Karma, Mocha, Tap and Vitest. A TypeScript checker is also available. An interactive initializer asks setup questions and writes a stryker.config.mjs file. Mutation runs start from the command line with npx stryker run. Without configuration, it uses npm test as the test command and mutates files in the lib and src directories. The repository is a monorepo holding the official Stryker packages.
