The presence of special symbols is an error.

example:

    test('test ^', () =>
    {
        console.log("hello ")
    });

When you click Debug.

The character ^ causes an error.

Console information:

Ran all test suites matching /PointInPolyline.test.ts/i with tests matching "test \\^".

I’m running into what might be the same thing when trying to debug a test with a backtick in the name:

❯ cd /Users/donovan/src/public/coffee-lex ; env "CI=vscode-jest-tests" /Users/donovan/bin/node --inspect-brk=49907 node_modules/jest/bin/jest.js --runInBand test.ts --testNamePattern "identifies `not of` as a single operator"
zsh: command not found: not

hmm… yup, backtick embedded in a test name is a problem. Looks like it needs to be handled differently than the normal regex escape…
