4 years ago Tarpaulin seems to work (but requires Linux): https://gist.github.com/jeamland/327032e1025efa620956926c99c90900
I tried using Mozilla's grcov but it requires nightly and breaks on a couple of upstream issues:
- basic-cookies depends (via lalrpop) on string-cache 0.7.5 which fails to build. I've submitted a patch to basic-cookies which updates their dependencies and avoids this and the patch has been accepted but we'll still need to wait for a new version.
- surf (on macOS) depends on core-foundation (via http-client -> async-native-tls -> native-tis -> secuity-framework) and that has a bug wrt finding a particular CF type ID. This has a fix upstream but needs a new version published with the fix in.
As we're starting to stabilize Tide's design, we'll want to work to improve resilience. A big part of that is to write tests to prevent regressions. To help inform us which parts of Tide are currently undertested it'd be good if we could have a (documented) way gather test coverage.
Perhaps we may want to integrate it as part of CI eventually as well, but for now simply having a way to measure code coverage would be great.
