[🚫 Bug] fail-zero flag in .mocharc.json is not respected

[EcksDy]

Describe the bug

When no tests are found, the fail-zero flag in specified .mocharc.json is not respected, and process still does exit 0, although no tests were found.
Logs can be found in the Test OS Ubuntu-latest - VSCode latest step.

P.S.
Test file exists, but no tests are found because of another unrelated issue with my build step. I've completely missed it because I was sure everything is alright since the tests pipeline was green 🤦‍♂️
I want to make sure that whenever no tests are found(files/tests), the ui-test fails.

Steps to reproduce

1. Checkout: https://github.com/EcksDy/vscode-env-switcher/tree/fix-not-failing-when-no-tests-run
2. Run `npm run install:all`
3. Run `npm run ui-test`

Logs

Extension 'env-switcher-0.5.2.vsix' was successfully installed.
Loading mocha configuration from ./src/ui-test/setup/.mocharc.json


  0 passing (1ms)

... exit 0
