ts-jest-test

Test case for debugging Jest tests written in Typescript. Issue

Steps to reproduce

1. yarn or npm install to install dependencies
2. Set breakpoint on line 6 of SystemUnderTest.spec.ts. (Just above debugger; statement)
3. Set breakpoint on line 3 of SystemUnderTest.ts. (Inside constructor).
4. Press F5 or click "Start Debugging".

Expected Behavior

Debugger should stop...

1. On line 6 of SystemUnderTest.spec.ts.
2. On line 3 of SystemUnderTest.ts.
3. On line 7 of SystemUnderTest.spec.ts.

Actual Behavior

Debugger only stops on line 7 of SystemUnderTest.spec.ts

Additional observations

VS Code reports that the breakpoints are loaded. They are not greyed out.

However, as the debugger reaches each expected breakpoint but doesn't it it, it will begin reporting a source map problem.

The "future" breakpoint (line 8 of SystemUnderTest.spec.ts) does not report any sourcemap problem.
