lwthiker 14de5bb0db Add impersonation support for Chrome 100 and 101
.. and for Edge 101 as well. The TLS fingerprint is identical to
previous versions. The HTTP headers have the usual differences in the
user agents. One important change though is in the way the HTTP2
SETTINGS frame is formed. Up until Chrome 98, there was an additional
randomly-generated setting in the frame. This seems to have been removed
since. Therefore it was removed from curl-impersonate as well, and
support for Chrome/Edge 98 was deprecated, since supporting both
signatures requires a lot of work.

The tests verify that curl-impersonate has the same network signature as that of the supported browsers. They do not test curl's functionality itself.

Running the tests

The tests assume that you've built both curl-impersonate-chrome and curl-impersonate-ff docker images before (see Building from source).

To run the tests, build with:

docker build -t curl-impersonate-tests tests/

then run with:

docker run --rm curl-impersonate-tests

This simply runs pytest in the container. You can pass additional flags to pytest such as --log-cli-level DEBUG.

How the tests work

For each supported browser, the following tests are performed:

  • A packet capture is started while curl-impersonate is run with the relevant wrapper script. The Client Hello message is extracted from the capture and compared against the known signature of the browser.
  • curl-impersonate is run, connecting to a local nghttpd server (a simple HTTP/2 server). The HTTP/2 pseudo-headers and headers are extracted from the output log of nghttpd and compared to the known headers of the browser.

What's missing

The following tests are still missing:

  • Test that curl-impersonate sends the same HTTP/2 SETTINGS as the browser.
