Sourcemap support when debugging (Intellij IDEA / Webstorm / others)

When debugging Jest tests in IDEA I set breakpoints but they are never triggered. I assume this is related to sourcemaps somehow.

Jest correctly gives Typescript filename+line when reporting errors / expect failures, so at this level sourcemaps are working.

This is more of a request for help than bug report. Do people have debugging fully working in your preferred IDE when running Jest tests?

For info, Jetbrains recently released integrated Jest support with progress bar, etc.

Here is the full command executed by IDEA:

"C:\Program Files\nodejs\node.exe" --debug-brk=7830 --expose_debug_as=v8debug C:\Users\alfie\gb\gb-util\node_modules\jest\bin\jest --config "{\"transform\":{\".ts$\":\"<rootDir>/node_modules/ts-jest/dist/preprocessor.js\"},\"testRegex\":\"(/__tests__/.*|\\.(test|spec))\\.(ts|tsx)$\",\"moduleFileExtensions\":[\"ts\",\"tsx\",\"js\"],\"rootDir\":\"C:\\Users\\alfie\\gb\\gb-util\",\"transformIgnorePatterns\":[\"/node_modules/\",\"^C:\\Program Files (x86)\\JetBrains\\IntelliJ IDEA 171.3780.15\\plugins\\JavaScriptLanguage\\helpers\"]}" --no-cache --runInBand --colors --setupTestFrameworkScriptFile "C:\Program Files (x86)\JetBrains\IntelliJ IDEA 171.3780.15\plugins\JavaScriptLanguage\helpers\jest-intellij\lib\jest-intellij-jasmine.js" --testPathPattern ^C:\\Users\\alfie\\gb\\gb\-util\\src\\misc\\FlexibleIterator\.spec\.ts$ --testNamePattern "^Flexible iterator Should yield last item after sub\-iterator$"

Hi @kulshekhar, thanks for response. Here is a link to minimal test project: https://github.com/jugglingcats/ts-jest-idea

It worked for me too. Example project and readme updated. Many thanks - we’re done here.
