VSCode Breakpoints work in test file but not in source files (via vscode-jest and jest/bin/jest)

[nathanwinder]

Current Behavior

When I debug my tests using VS Code and vscode-jest the breakpoints in the *.test.ts trigger but the breakpoints in the src *.ts files do not trigger. The breakpoint is a gray circle and states "Breakpoint ignored because generated code not found (source map problem?)".

Expected behavior

Breakpoints should be enabled for all source

So I don't use vscode-jest or the integrated debugger much, but was able to get breakpoints to work without much fuss in #577 (comment)

Notably I wasn't using vscode-jest there. But you're actually not using TSDX at all here when running your tests -- your program is ${workspaceFolder}/node_modules/jest/bin/jest.
That means the problem you're facing with breakpoints isn't related to TSDX as you're not using it for testing.

To use tsdx test you'd have to have ${workspaceFolder}/node_modules/tsdx/dist/index.js (and a test arg) as in the linked comment above.
It might also work with vscode-jest if you set it as the pathToJest, but idk
