cypress run specific test

cypress run --spec 'path/to/files/*.spec.js'

I think you're looking for --spec path/to/folder/*.js

You can run all the tests in a folder, or even in all subfolders of a folder

example:  --spec cypresss/integration/subsetA/**/*.js
would run all .js files in all folders under the "subsetA" folder in cypress/integration.

./node_modules/.bin/cypress run   // just cypress run wont work

npm install cypress                //takes about 3-5 minutes for entire process
./node_modules/.bin/cypress open   // just cypress run wont work

cypress run --spec path/to/file.spec.js
