A plugin to use the vitest test runner and framework in Stryker, the JavaScript mutation testing framework

// This file is used from the testing environment (via stryker-setup.js) and thus could be loaded into the browser (when using vitest with browser mode).
// Thus we should avoid unnecessary dependencies in this file.
