Coverage broken when using babel-jest

[jehoshua02]

The issue can reproduced by following these precise steps:

git clone https://github.com/jehoshua02/react-scaffold.git
cd react-scaffold
npm install
npm test -- --coverage

And I get this output:

~/projects/jehoshua02/react-scaffold 🚀  babel_jest
$ npm test -- --coverage

> react-scaffold@1.0.0 test /Users/employee/projects/jehoshua02/react-scaffold

As you can see, the tests run fine, and pass, the coverage is output to the console (which is all I really want), but something after that, I'm assuming when writing out reports to the disk, is failing and generating a big ugly error.

Issue also reported over at babel-jest.

[garetht]

@jehoshua02 I encountered this issue too when using babel-jest, but I think the problem is more general, in that any time the postprocessed file has more lines than the source file this error will be produced (if it has fewer I assume the coverage report will simply be incorrect). I tried this with the CoffeeScript example off the jest repo and got the same error. I'm wondering if it might be helpful to rephrase the issue?

[DaleLJefferson]

Same issue here, is there a workaround?

[wyuenho]

Any ideas how to solve this issue that I can try?

[ericwooley]

Im running into this also, so close to working!

[ericwooley]

The problem is in the istanbul package in report/html.js, there appears to be an some sort of error where the report is expecting another line and there is none. I changed the function to

function annotateLines(fileCoverage, structuredText) {
    var lineStats = fileCoverage.l;

    if (!lineStats) { return; }
    Object.keys(lineStats).forEach(function (lineNumber) {
        var count = lineStats[lineNumber];
        if(!structuredText[lineNumber]){
            console.log(lineNumber, 'does not exist in', structuredText);
        }
        structuredText[lineNumber].covered = count > 0 ? 'yes' : 'no';
    });
    structuredText.forEach(function (item) {
        if (item.covered === null) {
            item.covered = 'neutral';
        }
    });
}

and got

I think it is some kind of mapping error by babel, telling istanbul there is one more line then there should be? Not really sure though. Hopefully this can help someone with a little experience with these libraries.

[codyhatch]

Is there any progress on this?

[ericwooley]

I updated the versions and it seems to be working now. You can see how I am using it here https://github.com/ericwooley/react-in-style

[crestenstclair]

I'm still seeing this problem, on node v0.10.38

[screendriver]

Same here

[danielstern]

I'm experiencing this issue with Node v4.0.0 and Jest v0.5.2 with babel-jest 2.14.2

[koddsson]

Working for me on babel-jest: ^5.3.0, jest-cli: ^0.5.7 and node v4.1.0.

[quantizor]

Not working for me on babel-jest: ^6.0.1, jest-cli: ^0.8.0 and node v5.1.0

[cpojer]

I'd like to fix this if it is still causing trouble for people. Can someone provide me a proper repro against jest 0.8 or 0.9?

[cpojer]

This will be fixed in 0.9.2 tomorrow. #785 and #787.
