/**
 * Automatically launches [interactive pause](/basics/#pause) when a test fails.
 *
 * Useful for debugging flaky tests on local environment.
 * Add this plugin to config file:
 *
 * ```js
 * plugins: {
 *   pauseOnFail: {},
 * }
 * ```
 *
 * Unlike other plugins, `pauseOnFail` is not recommended to be enabled by default.
 * Enable it manually on each run via `-p` option:
 *
 * ```
 * npx codeceptjs run -p pauseOnFail
 * ```
 *
