Prerequisite

• are you able to run jest test from the command line? yes
• how do you run your tests from the command line? (for example: npm run test or node_modules/.bin/jest) npm run test (test script is "test": "react-scripts test --env=jsdom"

Steps to Reproduce

When running all tests in the project with Run Test (either from menu or green play button), the command generated is:

> react-scripts test --env=jsdom "--testLocationInResults" "--json" "--useStderr" 
  "--outputFile" "C:\\Users\\myName\\AppData\\Local\\Temp\\jest_runner_banana_web_frontend_myname_2.json" 
  "--no-coverage" "--reporters" "default" 
  "--reporters" "c:\\Users\\MyName\\.vscode\\extensions\\orta.vscode-jest-5.2.3\\out\\reporter.js" 
  "--colors" "--watchAll=false"

When running a test in Debug for a single test or single file (either from the Menu or green debug button) the command generated is:

${env:NODE_OPTIONS}=' --require "c:/Users/MyName/AppData/Local/Programs/Microsoft VS Code/resources/app/extensions/ms-vscode.js-debug/src/bootloader.js"  
--inspect-publish-uid=http'; 
${env:VSCODE_INSPECTOR_OPTIONS}=':::{"inspectorIpc":"\\\\.\\pipe\\node-cdp.19832-57a36fbd-1.sock",
"deferredMode":false,"waitForDebugger":"",
"execPath":"C:\\nodejs\\node.exe",
"onlyEntrypoint":false,"autoAttachMode":"always",
"fileCallback":"C:\\Users\\MyName\\AppData\\Local\\Temp\\node-debug-callback-4a66926ce44c1ec6"}';
 & 'C:\nodejs\npm.cmd' 'test' '--' 'test' '--env=jsdom' '--runInBand' '--watchAll=false' 
'--testNamePattern' 'Permission Util' 
'--runTestsByPath' 'C:\git\Banana\application\banana-web-frontend\src\test\util\permissionUtil.test.ts' 

When running a Run Test for a single test or single file (either from the Menu or green play button) the command generated is:

> react-scripts test --env=jsdom "--testLocationInResults" "--json" "--useStderr" 
"--outputFile" "C:\\Users\\MyName\\AppData\\Local\\Temp\\jest_runner_banana_web_frontend_myname_2.json" 
"--testNamePattern" "Permission Util" "--no-coverage" "--reporters" "default"
 "--reporters" "c:\\Users\\MyName\\.vscode\\extensions\\orta.vscode-jest-5.2.3\\out\\reporter.js" 
"--colors" "--watchAll=false" 
"--testPathPattern" "c:\\\\git\\\\Banana\\\\application\\\\banana-web-frontend\\\\src\\\\test\\\\util\\\\permissionUtil\\.test\\.ts"

Note the file name has extraneous backslashes inside the name of the file and all the backslashes are escaped unlike the paths in the Debug mode (which works as expected).

Relevant Debug Info

Here is the output:

No tests found, exiting with code 1
Run with --passWithNoTests to exit with code 0
In C:\git\Banana\application\banana-web-frontend
719 files checked.
testMatch: C:/git/Banana/application/banana-web-frontend/src//tests//.{js,jsx,ts,tsx}, C:/git/Banana/application/banana-web-frontend/src/**/.{spec,test}.{js,jsx,ts,tsx} - 303 matches
testPathIgnorePatterns: \node_modules\ - 719 matches
testRegex: - 0 matches
Pattern: c:\\git\\Banana\\application\\banana-web-frontend\\src\\test\\util\\permissionUtil\.test\.ts - 0 matches

Expected Behavior

Test is found and runs.

Actual Behavior

noticed you are using npm 7.x, which had issue with pass-through argument interpretation, see comment. Can you try with npm >= 8.15?
