Don't ignore node_modules

[RuneKR]

Hi,

This is basically a replica of: #1995 (comment)

Whenever you structure your project packages/node_modules/**/* the test doesn't get picked up. Have a fix been implemented via a config? I cannot find the solution at least

My project is organised:

• package.json
• node_modules
  • .bin
  • jest
• packages
  • node_modules
    • .bin (symlink)
    • @scope
      • packename
        • package.json
      • packagename
      • ...

Tests can be run if i run the tests from the root package.json but not from any of the package.json under packages/node_modules/. If i rename packages/node_modules to anything else then it works.

You can unignore some folders inside node_modules using this undocumented options:

"haste": {
  "providesModuleNodeModules": [
    "package-inside-node_modules-1",
    "package-inside-node_modules-2",
  ]
},

Also, if you want to collect coverage, use this solution: #5046 (comment).

Hi, thank you! I am still a little bit uncertain on how exactly to use this.

Which package.json should i add the configuration to and how to add it?
Is haste a configuration under jest in the package.json file?

[RuneKR]

I found a solution now, just ignore my previous question. Thank you @reklatsmasters ! I am not sure that i should close the issue yet as the haste config should really be documented.

Might just raise a PR for that.

So the "solution" was to do what you @reklatsmasters suggested. I am quite new to working with JEST so i didn't realise the heavy caching that jest is doing for us. For future reference. Every time one make a configuration change like this, just remember to run jest with --clearcache.

I guess this is partly documented in: https://jestjs.io/docs/en/tutorial-react-native#providesmodule so i'll close for now

@RuneKR Can you please share what you figured out to answer your questions above? As someone trying to get coverage for the source in my lib/node_modules directory, I have the same questions. What do I need to add to my package.json configuration and where does it go? :)

[RuneKR]

Hi sure thing!

I need to know a bit more about your project in order to provide the right code.

I have my configuration in the package.json:

"jest": {
 "haste": {
  "providesModuleNodeModules": [
    "package-inside-node_modules-1",
    "package-inside-node_modules-2",
  ],
 "coveragePathIgnorePatterns": [ "<rootdir>/node_modules"]
 ...
},
