Script for parallel Cypress specs execution locally

cypress-parallel-specs-locally

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;

How to run runner v1:

• yarn cy:run - single executor
• yarn cy:run:parallel:empty - with filtering
• yarn cy:run:parallel - all specs

How to run runner v2:

• yarn cy:run_v2 - single executor
• yarn cy:run_v2:parallel:empty - with filtering
• yarn cy:run_v2:parallel - all specs

How to run with mochawesome report:

• yarn prereport
• yarn cy:run:parallel:empty
• yarn postreport
