Couldn't load options using mocha - w/ reproduction

[parliament718]

Attached is a minimum reproduction.

I can't get a simple test to show up in the test explorer.

The error gives "Couldn't load options using mocha"

mocha-test.zip

My structure is relatively simple, and I have a "backend" folder which I inform the test explorer of using

"mochaExplorer.configFile": "backend/.mocharc.json",
  "mochaExplorer.cwd": "${workspaceFolder}/backend",

In my own project, I can run the tests manually. In the reproduction above, I cant even do that (complains about ts extension), however that's another issue. I would be happy to just see the test in the explorer, the rest works in my project.

I have tried using @swc/register (I use swc), and ts-node/register -- Same problem, can't load options

This is such a simple setup, what is wrong here.

@parliament718 I saw this in the bounty you raised in the replit. I have fixed it. Do have a look at the replit submission.

Same issue, I have my tests in a tests folder. They work with mocha using CLI. But I cannot make them run in the test explorer, I got a "Test discovery failed":
