- /**
- * The Jest farm (publicly called "Worker") is a class that allows you to queue
- * methods across multiple child processes, in order to parallelize work. This
- * is done by providing an absolute path to a module that will be loaded on each
- * of the child processes, and bridged to the main process.
- *
- * Bridged methods are specified by using the "exposedMethods" property of the
- * "options" object. This is an array of strings, where each of them corresponds
- * to the exported name in the loaded module.
- *
- * You can also control the amount of workers by using the "numWorkers" property
- * of the "options" object, and the settings passed to fork the process through
- * the "forkOptions" property. The amount of workers defaults to the amount of
- * CPUS minus one.
- *
- * Queueing calls can be done in two ways:
- * - Standard method: calls will be redirected to the first available worker,
- * so they will get executed as soon as they can.
- *
- * - Sticky method: if a "computeWorkerKey" method is provided within the
- * config, the resulting string of this method will be used as a key.
- * Every time this key is returned, it is guaranteed that your job will be
- * processed by the same worker. This is specially useful if your workers
- * are caching results.
