361 *
362 * @param {?string} [configFilePath=null]
363 * A string representing a file system path pointing to the config file
364 * whose default export is a function that will be used to set Karma
365 * configuration options. This function will be passed an instance of the
366 * `Config` class as its first argument. If this option is not provided,
367 * then only the options provided by the `cliOptions` argument will be
368 * set.
369 * @param {Object} cliOptions
370 * An object whose values will take priority over options set in the
371 * config file. The config object passed to function exported by the
372 * config file will already have these options applied. Any changes the
373 * config file makes to these options will effectively be ignored in the
374 * final configuration.
375 *
376 * `cliOptions` all the same options as the config file and is applied
377 * using the same `config.set()` method.
378 * @param {Object} parseOptions
379 * @param {boolean} [parseOptions.promiseConfig=false]
380 * When `true`, a promise that resolves to a `Config` object will be
381 * returned. This also allows the function exported by config files (if
382 * provided) to be asynchronous by returning a promise. Resolving this
383 * promise indicates that all async activity has completed. The resolution
384 * value itself is ignored, all configuration must be done with
385 * `config.set`.
386 * @param {boolean} [parseOptions.throwErrors=false]
387 * When `true`, process exiting on critical failures will be disabled. In
388 * The error will be thrown as an exception. If
389 * `parseOptions.promiseConfig` is also `true`, then the error will
390 * instead be used as the promise's reject reason.
