npm version

cypress-parallel

Reduce up to 40% your Cypress suite execution time parallelizing the test run on the same machine.

cypress cypress-parallel
cy-serial-small cy-parallel_small

Run your Cypress tests in parallel (locally)

How it works

🔍 - Search for existing Cypress tests
📄 - Read (if exists) a weight file
⚖️ - Split spec files into different threads
⚙️ - For each thread it runs the Cypress command you've passed as argument
📈 - Wait for all threads to finish and collects the result in a single report

How to use

Install

npm i cypress-parallel

or

yarn add cypress-parallel

Add a new script

In your package.json add a new script:

"scripts" :{
  ...
  "cy:run": "cypress run", // It can be any cypress command with any argument
  "cy:parallel" : "cypress-parallel -s cy:run -t 2 -d <your-cypress-specs-folder> -a '\"<your-cypress-cmd-args>\"'"
  ...
}

With Arguments

Sample:

-a '\"--config baseUrl=http://localhost:3000\"'

Launch the new script

npm run cy:parallel
