How to run a test under a debugger?

[jdm]

With the stock cargo test runner, it prints the path to a binary that I can run under lldb. I can't figure out how to do the same with nextest. Am I missing something?

For something equivalent to cargo test, you can get paths to test binaries with cargo nextest list --verbose.

But that won't help you if you need the environment setup performed by nextest. I'd love to have support for first-class debugger integration in cargo nextest run. Something like cargo nextest run --debugger "rust-gdb --args", which:

• disables timeouts
• puts nextest into no-capture mode (which makes tests be serial)
• allows for standard input to be passed through
• invokes test binaries with the specified debugger (can be added here:

  nextest/nextest-runner/src/list/test_list.rs

If you'd like to implement this feature, I'd love to accept a PR for it! That would probably make life easier for a lot of folks including yourself.
