I got the same issue and fixed it by unmocking React. See http://facebook.github.io/jest/docs/tutorial-react.html#setup Can you tell me if it fixes it
from jest.
Fantastic — that works, thanks! Is it a bug to be fixed, or is it intentional (and should be documented)?
from jest.
This is intentional, React is not meant to be mocked when tested against. But we can definitively do a better job at failing when it's not the case. This error is very cryptic
from jest.
Yea, I've been tracking this confusing error message here: #14
This week and last have been super busy for me, so I haven't had a chance to dive in to it just yet, but I'll throw it to the top of the queue since I think it should be a fairly simple fix.
If you have further questions or concerns, lets continue the thread in #14 to keep things centralized.
from jest.
Sounds good. I'd seen that issue earlier, but the title is misleading (in this case, there's nothing to do with module.exports). Maybe the scope/wording of #14 can be expanded?
from jest.
That's a good point -- I'll update the title
from jest.
I am seeing what appears to be the same issue in Jest V0.4, but I've added the unockedModulePathPatterns
entry as @vjeux suggested. Here is the jest section from my package.json
file:
"jest": {
"scriptPreprocessor": "<rootDir>/preprocessor.js",
"unmockedModulePathPatterns": [
"<rootDir>/node_modules/react"
],
"testFileExtensions": [
"js"
],
"moduleFileExtensions": [
"js",
"json"
]
I'm just using the test files at the moment with the CheckboxWithLabel component, and it is seg faulting. I'm just following this example: https://facebook.github.io/jest/docs/tutorial-react.html#content
node -v
v0.12.0
npm -v
2.5.1
jest -v
v0.4.0
from jest.
Seems I am probably seeing #243 / #266
