Script for parallel Cypress specs execution locally:
- runnner_v1 is a pool of promises with recursion - runner.js
- runner_v2 is an event based runner with state - runner_v2.js, for node 12+
Runner v2 tries to solve an issue with several Cypress xvfb instances spawned at same time and fighting for same resource causing skipping some suites. Now a parameter timeout could be configured, which blocks new instance from spawning cypress if timeout from previous start has not finished. Value of timeout should be some +/- average time between starting cypress and opened browser, and it depends on your test suite size and available machine resources.
Arguments:
executors = number of chainers which are picking specs to run;
filter = filtering specs path by keyword;
