Motivation

rust-analyzer has this nice little Run Tests button above a mod of tests:

It also has Run Test above a single test. When switching a project to nextest, most of the time Run Test still works, but often Run Tests will start to fail if you start letting your test suite take advantage of one process per test, i.e. Run Tests will invoke some call to cargo test and I'm fairly certain it will run those tests in parallel using multiple threads, but your test suite might expect multiple processes rather than multiple threads.

Proposal

Have you ever spoken with the rust-analyzer team to see if Run Tests could be extensible for other test backends to hook into?
