03 Test Execution - biswajitsundara/Cypress GitHub Wiki

We have different ways to execute the script/spec files

• Run this command node_modules\.bin\cypress open to launch the test runner
• Then select the spec file you want to run
• Top right corner we have the option to select the browser
• We can run single spec file or all the spec files at once.

• All specs in headless mode (electron) - node_modules\.bin\cypress run

• All specs in chrome browser - node_modules\.bin\cypress run --browser chrome

• Run a single spec file (headless):
  node_modules\.bin\cypress run --spec "cypress\integration\practice.js"

• Run spec files from a folder
  node_modules\.bin\cypress run --spec "cypress\integration\demo\**\*"

• Run a single spec file in chrome browser:
  node_modules\.bin\cypress run --browser chrome --spec "cypress\integration\practice.js"

• By default the specs will run in alphabetical order.
• Let's say we have two spec files practice.js and google.js
• Then it will execute the google.js first and then practice.js
• If we want to execute them in a specific order then update cypress.json file like below

{
    "testFiles": [
        "practice.js",
        "google.js"
    ]   
}

If we run using the command node_modules\.bin\cypress run --browser chrome then it will execute the practice.js file first and then google.js

1. We can also mention the command in package.json this way

"scripts": {
    "test": "node_modules/.bin/cypress run --browser chrome"
  }

Then for executing the test, just enter the command npm run test

2. Using the Cypress run command

"scripts": {
    "test": "cypress run --browser chrome"
  }

Then for executing the test, just enter the command npm run test

3. Using the Cypress Test Runner

"scripts": {
    "test": "cypress open"
  }

Then for executing the test, just enter the command npm run test
