Issue with version 24.3.0 using --changedSince flag

[fakiolinho]

🐛 Bug Report

I am using Babel 7 and Jest 24. After upgrading to v24.3.0 i have issues with command:

jest --config ./jest.config.json --changedSince=develop

The error i get is this:

ERROR: options.changedFiles.has is not a function
STACK: TypeError: options.changedFiles.has is not a function
    at shouldInstrument (/node_modules/@jest/transform/build/shouldInstrument.js:142:53)

Failed to collect coverage from /Header/index.jsx

If i don't use the --changedSince flag at all then tests run smoothly.

In order to tackle this now i am using resolutions in package.json:

"resolutions": {
    "jest": "24.1.0",
    "jest-cli": "24.1.0",
    "jest-config": "24.1.0",
    "babel-jest": "24.1.0"
}

To Reproduce

Add in package.json:

"babel-jest": "^24.3.0",
"jest": "^24.3.0",

and then clear everything with rm -rf node_modules yarn.lock and then install the new ones with yarn

Finally run jest with --changedSince flag:

jest --changedSince=develop

Expected behavior

Jest tests should not fail and run flawlessly

Link to repl or repo (highly encouraged)

Run npx envinfo --preset jest

Can you provide a repo with repro?

[fakiolinho]

Sorry @thymikee i cannot really share the original repo itself. Do you want me to create a dead simple one with a couple jest tests for 24.3.0 version? Would that be of any help?

[thymikee]

Yep, a minimal reproduction with only what's necessary :)

[SimenB]

Seems like something somewhere passes changedSince as an array instead of a Set? A reproduction would be awesome 🙂

[SimenB]

Ah, wait. I know. Options here are serialized, and the Set is lost: https://github.com/facebook/jest/blob/afe22419327d2470bab9187e10fa153e2056bed9/packages/jest-reporters/src/coverage_reporter.ts#L173

Wanna send a PR? 😀

I think the correct solution is to pass this as an array. You can do Array.from(set)

Is there a date on when is this going to be released? Not being able to watch tests if coverage is enabled is quite a pain.

[KSXGitHub]

When will this be released?

[robdonn]

@leonfs @KSXGitHub

v24.4.0 has been released

(BTW, fix worked perfectly for me. Thanks @thymikee )

[yoshicarroll]

v24.4.0 does not fix #8088.
watch is still broken.

[robdonn]

Not saying that this will fix the issue for others but it’s what I did and it worked for me:

• Deleted node_modules folder
• Deleted yarn.lock file
• Updated versions of Jest packages to 24.4.0 in package.json
• Ran yarn install

[philiiiiiipp]

Not sure if this is the correct place to post this, but I am also still seeing the #8088

I did delete node_modules and reinstalled jest + jest-circus to the latest version 24.4.0

npm list jest jest-circus babel-jest

I also installed watchman and tried running it with that but it just seem to hang while running it with --no-watchman just fails with:

2019-03-12 09:55 node[16317] (FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-22)

Error: Error watching file for changes: EMFILE

I am running OSX 10.14.3 and saw the same issue on another mac as well.

EDIT

I am now also seing the issue on [email protected], which I am fairly certain that this is where it worked out fine before.

npm list jest jest-circus babel-jest

Would it be possible to reopen #8088 as it appears it is still a problem even after the 24.4.0 upgrade?
