curl_easy_reset() may be used by an application to reset the options on a curl handle. If an app has the CURL_IMPERSONATE env var defined, then the impersonation options are automatically set in curl_easy_init() but will be cleared in a call to curl_easy_reset(). The desired behavior is for the impersonation options to be retained (as they are "transparent" to the user), which this commit takes care of. Note that this only has an effect when libcurl-impersonate is loaded and the CURL_IMPERSONATE env var is set. Otherwise the regular behavior of resetting all the handle options is retained. Test that the unique TLS signature of curl-impersonate is preserved after a call to curl_easy_reset() when libcurl-impersonate is loaded. For this purpose change the 'minicurl' testing util to support multiple URLs and launch it with 2 different URLs when testing the TLS signature.
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 localnghttpd
server (a simple HTTP/2 server). The HTTP/2 pseudo-headers and headers are extracted from the output log ofnghttpd
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.
