Add a custom Playwright configuration

Runs execute under a named configuration — Default unless told otherwise. Here's how to add a Mobile one.

1. Read the default as your reference

   testvibe files get Configurations/Default.config.js

   Your config should keep the same shape — it's a standard Playwright config module the sandbox loads as-is.

2. Write the new configuration

   mobile.config.js

   module.exports = {
     use: {
       browserName: 'chromium',
       viewport: { width: 390, height: 844 },
       isMobile: true,
       hasTouch: true,
     },
   };

   testvibe files put Configurations/Mobile.config.js --file ./mobile.config.js

   The file name is the config name: Configurations/Mobile.config.js → Mobile. (Writes outside Features/ or Configurations/ are rejected — see the allowlist.)

3. Verify and run

   testvibe configs
   testvibe run "Login Functionality" --config Mobile --wait

   Over REST that's POST …/features/12/run with {"config": "Mobile"} — see run_feature.

info

Configurations apply per run — the same generated tests execute under any config, so one feature can be green on desktop and red on mobile. That's the point.
