Feature request: Expose test name as an environment variable

[liranco]

Motivation

Writing test assets with the test name

Proposal

It can be useful if nextest will expose the current test's name as an environment variable (perhaps NEXTEST_TEST_NAME).

This is useful when tests output assets, since the test name can be used as the asset's filename.

Alternatives

No response

Additional context

Yeah, seems pretty reasonable to me! I think we should expose basically the set of things exposed by USDT probes: https://docs.rs/nextest-runner/latest/nextest_runner/usdt/struct.UsdtTestAttemptStart.html

Would you like to prepare a PR for this? See

nextest/nextest-runner/src/test_command.rs

Line 92 in 89a7739

cmd.current_dir(cwd)

for where the logic to set environment variables lives.
