/**
* Extension to start and stop processes per suite.
* Can be used to start/stop selenium server, chromedriver, phantomjs, mailcatcher, etc.
*
* Can be configured in suite config:
*
* ```yaml
* # acceptance.suite.yml
* extensions:
* enabled:
* - Codeception\Extension\RunProcess:
* - chromedriver
* ```
*
* Multiple parameters can be passed as array:
*
* ```yaml
* # acceptance.suite.yml
*
* extensions:
* enabled:
* - Codeception\Extension\RunProcess:
* - php -S 127.0.0.1:8000 -t tests/data/app
* - java -jar ~/selenium-server.jar
* ```
*
* In the end of a suite all launched processes will be stopped.
*
* To wait for the process to be launched use `sleep` option.
* In this case you need configuration to be specified as object:
*
* ```yaml
* extensions:
* enabled:
* - Codeception\Extension\RunProcess:
* 0: java -jar ~/selenium-server.jar
* 1: mailcatcher
* sleep: 5 # wait 5 seconds for processes to boot
* ```
*
* HINT: you can use different configurations per environment.
