This is insane 👀 being able to mock API requests for functional tests is super powerful if used properly 👏

[Udzial]

this is awesome.. i think we can even read bearer token using this and then use it in API

[venkateshgoud]

Hi Rahul, I just need to know that can we achieve this using C# because I didn't come across any such method/library or nuget package with which I can achieve it. Any help would be appreciated. Thanks.

Hello Sir, Thank you for this video.I am facing a weird issue while running this script. devtools.addListener(Fetch.requestPaused(), request-> is not getting invoked. Hence the network is not intercepted. I don't get any error so able to resolve the issue. If you could help, it will be really helpful for my project.

Hi Rahul, how do I intercept network call for chrome version 116. Until chrome version 115, this was working but now I am getting devToolsExcetion and it is asking me to "include an implementation on the class path, possibly by adding maven dependency of devTools matching my browser version. Unfortunately I am not able to fine devTool dependency to match chrome 116.

Great informative tutorial. Is it possible to capture network responses, for example, if I need entire response of one the network log that is loaded on particular page, is ir possible to do with devtool?

[HenryLeu]

How do you get the response body back from the Network tab? I need to know the response body in order to do the validation. Thanks!
