🐛 Bug Report

when i set jest config in package.json like this

"jest": {
        "verbose": true,
        "collectCoverage": true,
        "globals": {},
        "testEnvironment": "jest-environment-jsdom-global",
        "moduleFileExtensions": [
            "js",
            "jsx",
            "json"
        ],
        "moduleNameMapper": {
            "^@/(.*)$": "<rootDir>/src/$1",
            "\\.(css|less)$": "<rootDir>/__mocks__/styleMock.js"
        },
        "transform": {
            "^.+\\.(js|jsx)$": "<rootDir>/node_modules/babel-jest",
            "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/__mocks__/fileTransformer.js"
        },
        "transformIgnorePatterns": [
            "<rootDir>/node_modules/"
        ],
        "setupFiles": [
            "jest-canvas-mock"
        ],
        "testMatch": [
            "<rootDir>/**/*.(test|spec).js"
        ],
        "coverageDirectory": "<rootDir>/test/unit/coverage",
        "collectCoverageFrom": [
            "<rootDir>/**/util.js"
        ],
        "coveragePathIgnorePatterns": [
            "<rootDir>/node_modules/",
            "<rootDir>/test",
            "<rootDir>/tasks",
            "<rootDir>/config"
        ]
    },

when i run yarn run jest, i get this

Can you try on the latest version of Jest? Also please try to form the issue a bit clearer, because I have troubles understanding :<

[z2014]

i have update jest 24.9.0 version, it also has this problem.

the problem is collectCoverageFrom didn't work. i set jest config collectCoverageFrom: ['<rootDir>/**/util.js'] so i want to collect Coverage the files named 'util.js' , but it collect all the files

@z2014 - I guess your regex is not working correctly not sure with your code. but I am able to ignore files using below code .

collectCoverageFrom: ['<rootDir>/src//*.{js,jsx,ts,tsx}', '!<rootDir>/src//*css.ts'],

try add in collectCoverageFrom: ['<rootDir>/src/**/*util.js'],

[z2014]

@SunilSalve ['/src//*.{js,jsx,ts,tsx}', '!/src//*css.ts'] is css.ts right ? can you provide a complete code, thanks

collectCoverageFrom still doesn't collect coverage for React components? I'm trying it with "src/**/*.{ts,tsx}" and it indeed doesn't cover React components. 🤷🏻‍♂️
