Can't make it run when using vitest.

[yoniaiz]

Hi!
I'm trying to run the tests using vitest and it does not seem to work.
I didn't create any vitest configuration, when i'm running the tests that use runCommand i'm getting the following error

stdout  (node:99331) [ERR_UNKNOWN_FILE_EXTENSION] Warning: TypeError
module: @oclif/core@4.0.31
task: findCommand (local)
plugin: test-reports-cli
root: /.../my-cli
code: ERR_UNKNOWN_FILE_EXTENSION
message: Unknown file extension ".ts" for .../src/commands/local.ts
See more details with DEBUG=*

Is there any guidance or known issues running the tests using vitest?
