Cannot find module '<project path>/src/package.json' after run (by mistake) create package.json

Created June 08, 2021 00:09

Hello, good day, I've an annoying problem, I wanted to jump to the package.json file but by mistake I click over "package.json file File|New" this actions created a new package.json file under my src directory...ok I removed this and hope everything works as expected...but nope...after remove this new created file when I try to run my test I get this error

Error: Cannot find module '/<my folder>/src/package.json'

If I run the test using the command line, this works as expected, by the way, we're talking about a create-react-app project

In desperation I decided to delete the .idea file thinking that it was better to regenerate it because a strange configuration could have been added there, this didn't work, even worse, now I don't have the button to run test inline in my test file (you know, the handly button at the right of the line number in the editor)

It is a bit impressive as a small error can cause a loss of time of this caliber, I hope you can tell me how I can fix my editor to correct this problem :tired_face:

thank you so much, have a great day

after remove the .idea folder for second time and restart the IDE seems work fine again :D...seems very dangerous use that create package.json file and this does things behind the scene that users probably doesn't expect...

Just creating a package.json doesn't normally do anything of this kind; you must have changed the run configuration you were using to run your tests (by choosing a different package.json or working directory there)

thank you Elena Pogorelova, my unit test are working as expected but my e2e test doesn't run through the IDE, I can run manually them through the cli but the issue with the package.json path still fails

Error: Cannot find module '..../src/e2e/package.json'

I've this folder structure

src

--/e2e/

----/specs/

-------index.e2e.ts

----jest.config

----jest-playwright.config.js

jest.config

module.exports = {
  preset: 'jest-playwright-preset',
  testMatch: ["**/specs/*.e2e.ts"],
  /*transform: {
    "\\.js$": "react-scripts/config/jest/babelTransform"
  },*/
 transform: {
    '^.+\\.ts?$': 'ts-jest',
  },
}

jest-playwright.config.js

// https://github.com/playwright-community/jest-playwright/#configuration
module.exports = {
  browsers: ['chromium', 'firefox', 'webkit'],
  serverOptions: {
    command: `npm start`,
    port: 5000,
    launchTimeout: 10000,
    debug: true,

    verbose: true
  },
  launchOptions: {
    headless: false
  }
}

when I clicked the run button the IDE automatically generate the configuration for run the test

seems to be correct:

configuration file is set to jest.config.js

jest package is /node_modules/react-scripts

working directory is src/e2e

test file is index.e2e.ts

I don't know why this e2e test (unit test are working fine) points to some weird package.json inside the /src folder...

hope you can know which is the problem here...thank you so much!

Hmm... Likely because of

`npm start`

command in your jest-playwright.config.js - it requires a package.json with the corresponding script to run. Not sure how it can work for you outside of the IDE...
