/**
|
|
* 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.
