What and why?
Web was not properly adding the trace sample rate, nor was it properly checking the
firstPartyHost
against the requested URL correctly. Both of these are fixed.As part of this, I added web as a platform on the tracing package. Web doesn't actually use our http tracking module, but the tests for http tracking live in that module.
Additionally, add sanity tests for the Dio, which we assume works because it uses HttpOverrides on mobile (which our plugin intercepts) and XMLHttpRequest on web (which the Browser SDK intercepts). Adding an integration test to ensure it's working on all supported platforms and that we don't break it moving forward.
