This tool uses debug symbols of a Rust libtest (or compatible) binary to create a mapping of test names to test source locations. The purpose of this is to augment test reports with links to tests, for example for mutation test reports.
We run the test binary with --list --format=terse to get a list of test names.
We also extract all the function names and source locations from the debug symbols of the binary using the symbolic_debuginfo crate.
Then we heuristically match the test names to the function names.
Run wheretests <TEST BINARY LOCATION>. Example of use:
$ wheretests ./target/debug/deps/typst_syntax-e82ce8371a857995
