Wallaby now supports Vitest when configured to run tests in child processes. When Vitest
v0.0.29+ is configured with
threads: false, tests are run in a
child_process instead of
worker_threads. This change in where your tests are executed allows APIs like
process.chdir to be used, which were not available when running with Vitest’s default
worker_threads. To benefit from this enhancement, ensure your Wallaby and Vitest are updated to the latest versions.
