Possible solution: For me, the reason why I couldn’t hit the correct line was due to sourcemaps being incorrect/absent due to an issue with ts-jest when Jest’s collectCoverage option was set to true. https://github.com/kulshekhar/ts-jest/issues/917

Setting that to false allowed the green CodeLens [debug] button to properly hit my code at the desired lines.

Not sure if or how this can be used to fix this issue

Below is a config that works

    {
      "type": "node",
      "request": "launch",
      "name": "Jest All",
      "program": "${workspaceFolder}/node_modules/jest/bin/jest",
      "args": ["unit", "--runInBand"],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "disableOptimisticBPs": true
    }
