ENOENT: No such file coverage-summary.json

[webpolis]

Hi

I set it up exactly as explained in master's README but it fails with below error. Using Jest v26.0.1:

Error: ENOENT: no such file or directory, open './coverage/coverage-summary.json'
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] test:badges: `npm run test:coverage && jest-coverage-badges`
npm ERR! Exit status 1

Thanks

I tried running npm run test:coverage && jest-coverage-badges --input ./coverage/coverage-final.json
but got

So it seems like a version problem

There are couple of things to be added: Make sue you have the jest command added under your package json script:

  "test": "jest",
   "test:coverage": "npm test -- --coverage",
   "test:badges": "npm run test:coverage  && jest-coverage-badges 

Also make sure you have all the jest output files going into coverage folder. For that you need to added the below config in jest.config.js:
coverageDirectory: "coverage"

Thanks.

But is the same. It keeps returning the same error. Now, in a new blank project.

My jest.config:

module.exports = {
  preset: "ts-jest",
  testEnvironment: "jsdom",
  transform: {
    ".(ts|tsx)": "ts-jest",
  },
  moduleFileExtensions: ["ts", "tsx", "js", "json"],
  coverageDirectory: "coverage",
};

My package.json scripts:

    "test:badges": "npm run test:coverage  && jest-coverage-badges",
    "test:coverage": "npm test -- --coverage",

Coverage runs great, it just fail when I use this tool.

Make sure you have json-summary in the coverageReporters configuration:

"jest": {
  "coverageReporters": [
    "json-summary", 
    "text",
    "lcov"
  ]
}

this reporter is responsible for generating the coverage-summary.json file

[webpolis]

Thanks, but that's also there. As someone mentioned here, it's a version issue. Currently, this package is outdated in relation with its dependencies.

[hollandjake]

I had this issue. FIX was to ensure you dont have a jest.config.js file this will be override the package.json. Optionally you can add the configs into the jest.config.js

[Running on jest 26.6.0]

[elgsantos]

I had this issue on windows, for me the solution was to remove the quotes from input and output:
jest --coverage && jest-coverage-badges --input coverage/coverage-summary.json --output __badges__

( "jest": "^26.6.3", "jest-coverage-badges": "^1.1.2")

[ghost]

For those who are still experiencing this issue, if you got a specific jest.config.js in your project, make sure to set the json value in coverageReporters option exactly as indicated by @gabrielsiedler on his example, so:

coverageReporters: [
    "json-summary", <- Not "json" but "json-summary": this is important!
    "text",
    "lcov",
    "clover"
  ]

[RicardoGomesRocha]

@hollandjake and @elgsantos (here and here).

So, @pamepeixinho I think this issue can be closed.

[ciriousjoker]

Can be closed imo.

Basically, copy coverageReporter from package.json into jest.config.js:

/** @type {import('ts-jest/dist/types').InitialOptionsTsJest} */
module.exports = {
  preset: "ts-jest",
  testEnvironment: "node",
  // here:
  coverageReporters: ["json-summary", "text", "lcov"],
};

[jrichardsz]

Make sure you have json-summary in the coverageReporters configuration:

"jest": {
  "coverageReporters": [
    "json-summary", 
    "text",
    "lcov"
  ]
}

this reporter is responsible for generating the coverage-summary.json file

Worked for me, thanks!!

"jest": "^27.3.1",
"jest-badge-generator": "^1.1.5"

For me worked when I add some files an directories to ingore, remember to check this too.
Worked when I fixed the paths to ignore like this:

coveragePathIgnorePatterns: ['/node_modules/', 'src/infra/db/*']
