Coverage shows 0% in windows 11 but works good in WSL2

[chouzz]

• Version: 8.0.1
• Platform: windows 11 and wsl2
• Nodejs: both v16.14.0 in windows11 and wsl2

Reproduce steps:

1. Generate vscode sample extension

   npm install -g yo generator-code
   yo code 
   // input extension-test and other can be default

2. Install c8, according to https://stackoverflow.com/questions/71664061/how-to-generate-a-coverage-report-with-vscode-extension-tests

3. Make a sample test case: Make new file in src called resolvedPath.ts

   import * as path from 'path';
   
   export function createResolvedFilePath(...pathParts: string[]) {
     return path.resolve(...pathParts);
   }

   make test file in test/suite/resolvedPath.test.ts

   import * as assert from 'assert';
   import { createResolvedFilePath } from '../../resolvedPath';
   
   suite('Suite::Tests::ResolvedPath', async () => {
     test('Test::should return full path', async () => {
         const resolvedPath = createResolvedFilePath('/home/user/src/main.cpp');
         assert.strictEqual(resolvedPath, '/home/user/src/main.cpp');
     });
   
   });
   

   And use this function in extension.ts

   export function activate(context: vscode.ExtensionContext) {
   
     // Use the console to output diagnostic information (console.log) and errors (console.error)
     // This line of code will only be executed once when your extension is activated
     console.log('Congratulations, your extension "extension-test" is now active!');
     // add test function
     const resolvedPath = createResolvedFilePath(
         process.platform === 'win32' ? 'd:/' : '/', 'user', 'src');
     console.log(resolvedPath)
     // The command has been defined in the package.json file
     // Now provide the implementation of the command with registerCommand
     // The commandId parameter must match the command field in package.json
     let disposable = vscode.commands.registerCommand('extension-test.helloWorld', () => {
         // The code you place here will be executed every time your command is executed
         // Display a message box to the user
         vscode.window.showInformationMessage('Hello World from extension-test!');
     });
   
     context.subscriptions.push(disposable);
   }

4. run coverage command

   npm run coverage

In wsl, it works good:

    ✔ Sample test
  Suite::Tests::ResolvedPath
    ✔ Test::should return full path
  2 passing (9ms)

But in windows 11, it doesn't work:
