The Coverage job has failed on every run since at least eclipse-biscuit#343, on main and on every pull request: test test_error_msg has been running for over 60 seconds ERROR cargo_tarpaulin: Failed to run tests: Error: Timed out waiting for test response `biscuit-quote` has a single test, a trybuild compile-fail check. Under tarpaulin it spawns a nested cargo build with the coverage RUSTFLAGS, which recompiles the dependency tree from scratch and exceeds tarpaulin's 60 s per-test timeout. Measured locally (Xeon 2.6 GHz, cold trybuild cache as on CI): cargo test -p biscuit-quote test 0.33 s, total 0.47 s cargo tarpaulin -p biscuit-quote --timeout 3600 test 123.6 s, total 137 s reported coverage: biscuit-quote/src/lib.rs: 0/307 lines Raising the timeout would therefore add about two minutes to the job (more on GitHub runners) and contribute no coverage: procedural macros run inside rustc, outside the traced test binary, so the crate reports zero lines either way. Exclude the crate from the tarpaulin invocation. It is still built and its macros are still exercised by the biscuit-auth tests. With the exclusion the workflow's exact command completes in about 45 s and writes cobertura.xml.
