How to simulate a slow internet speed in the browser?



  • There is such a moment when a client with a very slow Internet and an old slow system, when opening a web page, it shows some defects, which are not visible on fast machines because a person does not have time to notice them. How can you simulate such a slow loading to see such defects in manual web testing?

    There is a good tool in Chrome browser. It's called "Slow 3G". You can find it by opening Dev tools (F12) -> Network
    and choose Slow 3G as it's on the screenshot:

    Also you can specify Custom speed and Latency going to Custom -> Add... menu item
