The whole url gets replaced and I don't see the testcafe frame anymore. It happens when the test is ran against the website being hosted on amazon cloudfront, but if I run the test against the website hosted on localhost, then the redirection works, it doesn't replace the whole url and I can still see the testcafe frame.
Redirect on localhost looks like:
http://<testcafe-ip>:38279/I2zW8XmMh*tOCn5CTOd/<some-new-url>
Redirect on cloudfront looks like:
<some-new-url>
Do you know if amazon cloudfront has some security integrated which might be preventing the website from being embedded into testcafe?
I had the same issue. It works after setting the flag "disablehttp2" https://testcafe.io/documentation/402638/reference/configuration-file#disablehttp2
It seems testcafe-hammerhead has issues with redirection and http2. For me disabling http2 is fine, but there might be cases where it's not. Hope they fix this in hammerhead.
