Please provide a repro somebody can download and triage.
Dear Michal,
The bug template says providing a repro is optional (not required).
This can be reproduced using ANY vanilla install of NodeJS with the attacked package.json file provided.

It's optional, that's why I'm not closing this issue :) (however I could do it, because you removed quite some important information, like which version of Jest you use, which Node, which OS). But it will make it easier for us to triage this.
For example, without a repro project, there's like 1% chances I'm gonna look at it. It's dramatically higher with a repro. Your choice! 🙂
Fair enough:
Jest Version: 24.8.0 (latest) OS: Confirmed to fail on windows, Mac & Linux Node :10.15.3
Hello. I am also having an issue. Here is a repro: https://github.com/stonefruit/repro-jest-coverage.
npx create-react-app repro-jest-coverage
cd repro-jest-coverage
npm test -- --coverage
The above is used to create the repro. The coverage shown 'All files' with all 0s as described by @n8ores.
npm test -- --coverage
PASS src/App.test.js

Since there is a test for App.test.js, I think we should be expecting something that looks like (not accurate):

I found the solution to the problem. In the "jest": ...
part within package.json
substitute the ./
root for <rootDir>
.
"jest": {
"collectCoverageFrom": [
"<rootDir>/test/**/*.js"
],
"coveragePathIgnorePatterns": [
"<rootDir>/node_modules/",
"<rootDir>/tools/",
"<rootDir>/build/",
"<rootDir>/docs/"
]
@diazgilberto that did not work for me unfortunately.

@cansin do you have your jest settings inside package.json
?
Yes, I realized doing jest --coverage
works, versus having collectCoverage: true
inside jest.config.js
does not.

Interesting is that even though I have all jest
configuration inside package.json
I still need an empty jest.config.js
file in project root. If I remove that file, code coverage reports 0 again.
Now I'm having a different issue where coverage is reporting wrong %
stating that I'm missing to test a particular line of code.
This is the code that is reporting wrong coverage
if (value.length === 0 && defaultValue !== undefined) {
console.log('VALUE: ', value, ' DEFAULT: ', defaultValue)
return defaultValue
}
console.log()
inside the function that clearly shows that the function is getting tested.
console.log lib/validation/validateString.js:38
VALUE: DEFAULT: test

Watch out for this warning:
ts-jest[versions] (WARN) Version 24.9.0 of jest installed has not been tested with ts-jest. If you're experiencing issues, consider using a supported version (>=22.0.0 <24.0.0). Please do not report issues in ts-jest if you are using unsupported versions.
Downgrading jest fixed the bug for me without changing the command. I also did not add the --watchAll
flag.
Hi, We can follow the below jest configuration...
"jest": { "moduleFileExtensions": [ "js", "json", "ts" ], "rootDir": ".", "testRegex": ".spec.ts$", "transform": { "^.+\.(t|j)s$": "ts-jest" }, "coverageDirectory": "./coverage", "testEnvironment": "node", "collectCoverage": true, "verbose": true }
I'm having the same issue here.

I also had the similar issue before. My jest and ts-jest versions are: "ts-jest": "^26.3.0", "jest": "^26.4.2",
Here is my solution:
"collectCoverageFrom": [ "**/*.{js}", -> "**/*.js"
this will show correct coverage.
Hope this helps.
I also had the 0% coverage problem when running jest with the --config=configPath
to be the root directory and thus doesn't find any files to check the coverage for.
My solution was simply to go higher in the directory tree:
{
"rootDir": "../.",
...
}
What is the final solution for this issue? My app provides a 0% coverage: https://github.com/web-needle/sappio
Not sure if this is separate issue or same issue:
Steps:
http-error.ts
) not covered by tests on main branchwith parameter: --changedSince=main
with config which forces scanning all files:
collectCoverageFrom: [
"<rootDir>/**/*.js",
"<rootDir>/**/*.ts",
"<rootDir>/**/*.cjs",
],
Result:
Tests are not run and changed file will not be listed and jest will not fail:
Output
No tests found related to files changed since "main".
Run Jest without `-o` or with `--all` to run all tests.

----------|---------|----------|---------|---------|-------------------
All files | 0 | 0 | 0 | 0 |
----------|---------|----------|---------|---------|-------------------
Recovery step:
Change any other file covered by tests. This will trigger test run -> proper report, including files with 0 coverage:

🐛 Bug Report
Running JEST with code coverage enabled does not fail if the code coverage is 0%
To Reproduce
Enable JEST with the following configuration file
"jest": { "collectCoverage": true, "coverageDirectory": "../coverage", "testPathIgnorePatterns": [ "/node_modules/" ], "verbose": true, "coverageThreshold": { "global": { "branches": 50, "functions": 50, "lines": 50, "statements": 50 } } },
Then call your JEST script.
Expected behavior
JEST should fail with exit code 1 as the coverage limits are set to 50% and the test returned 0%.
Still having this problem on Jest 29.6.1
I'm having this same issue with:
When running: jest --coverage --coverageThreshold='{"global":{"statements":"70"}}' --changedSince origin/master
I get the same:
No tests found related to files changed since "origin/master".
Run Jest without `-o` or with `--all` to run all tests.
----------|---------|----------|---------|---------|-------------------
File | % Stmts | % Branch | % Funcs | % Lines | Uncovered Line #s
----------|---------|----------|---------|---------|-------------------

----------|---------|----------|---------|---------|-------------------
In the commits that I made in my branch, I specifically modified .js files that don't have any tests. I should be able to somehow ask it to fail when 'No Tests are found'. Especially because I want this to fail in a GitHub Action to not let developers get a free pass on not writting any tests.
Thanks, C
I'm having the same issue on jest 29.7.0
... the tests command pass regardless of test coverage.. no amount of tweaking and configuring fixed it... test always PASS if they succeed but even tho I'm specifying at least 80% coverage (in all the ways in can be configured) the commands never fails when under it.
Disregard my comment, the output was confusing, the test are PASSING but the command itself is indeed returning 1
when coverage is not met
