How to run Cypress headed tests using Chrome Incognito

Question

I run my tests using the below synbtax. The issue i see is my organization is has extensions that block chrome headed tests from running. The tests run smooth headless using chrome but get blocked when they run headed using chrome. I am wondering if there is a way to run chrome headed using incognito.

npx cypress run --browser chrome --headed

how about you pass the flag `--incognito` and check if this works or not ? — Alapan Das, Aug 24 '21 at 04:51

Within the cypress\plugins\index.js file put this code:

module.exports = (on, config) => {
on('before:browser:launch', (browser = {}, launchOptions) => {
        if (browser.family === 'chromium' && browser.name !== 'electron') {
            launchOptions.args.push("--incognito");                
            return launchOptions
        }

        if (browser.name === 'electron') {                
            launchOptions.preferences.incognito = true               
            return launchOptions
        }
    })    
}

I have used cypress and I ran my cypress test runner in incognito mode. All you need to do is to provide the below code in your index.js file inside the plugins folder of cypress.

 module.exports = (on, config) => {
 
   on("before:browser:launch", (browser, launchOptions) => {
     console.log(launchOptions.args);
     if (browser.name === "chrome") {
       launchOptions.args.push("--incognito");
     }
     return launchOptions;
   });
 };
