You can also use a replay proxy to find regressions on your web page.\n\nRead all about the setup in [the sitespeed.io WebPageReplay documentation](https://www.sitespeed.io/documentation/sitespeed.io/webpagereplay/).\n\n\nStart by installing sitespeed.io and clone this repo:\n\n1. `npm install -g sitespeed.io`\n2. `git clone git@github.com:sitespeedio/replay.git`\n\nGo into the cloned repo and then you can use our example configuration files to run the tests.\n\n### Testing desktop\n\nTo run tests on desktop use the configuration file for desktop:\n\n\n```bash\n./replay.sh --config desktop.json https://www.sitespeed.io -n 5 -b firefox\n```\n\n## Testing Android\nRunning your tests on an Android you first need to [install ADB and prepare your phone for testing](https://www.sitespeed.io/documentation/sitespeed.io/mobile-phones/#prerequisites).\n\nThen make sure you use the *android.json* configuration file and pass on *ANDROID=true* to the script. The script will then use the first attached Android phone it finds using *adb devices*.\n\n```bash\nANDROID=true ./replay.sh --config android.json https://www.sitespeed.io -n 5 -b chrome\n```\n\nIf you have multiple phones attached you probably want to run on a specific phone. You can choose phone by passing the DEVICE_SERIAL.\n\n```bash\nANDROID=true DEVICE_SERIAL=ZY322GXR4B ./replay.sh --config android.json https://www.sitespeed.io -n 1 -b firefox\n```\n\nIf you want to slow down your test, you can add latency on your localhost that serves the web page. \n\n```bash\nANDROID=true ./replay.sh --config android.json --browsertime.connectivity.engine throttle --browsertime.connectivity.throttle.localhost true --browsertime.connectivity.profile custom --browsertime.connectivity.rtt 100 https://www.sitespeed.io\n```","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsitespeedio%2Freplay","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsitespeedio%2Freplay","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsitespeedio%2Freplay/lists"}
