Broken React example

[popham]

Here's my initialization sequence: git clone https://github.com/facebook/jest.git && cd jest && npm install && npm install react && npm install react-tools && cd examples/react && node ../../bin/jest.js. I get the following error:

TypeError: .../jest/node_modules/react/addons.js:
.../jest/node_modules/react/lib/ReactWithAddons.js:
.../jest/node_modules/react/lib/React.js:
.../jest/node_modules/react/lib/ReactCompositeComponent.js:
Cannot read property 'DEFINE_MANY' of undefined

If you run npm install inside the examples/react directory, then react and react-tools will be installed there, causing them to be properly unmocked from the path specified in examples/react/package.json; you'll get this output:

jest/examples/react$ npm test

> node ../../bin/jest.js

Using Jest CLI v0.1.17

Hi, i'm facing similar issue when testing React.
My folder structure:

app/
     /__tests__/
                    /CheckboxWithLabel-test.js
    /CheckboxWithLabel.js
    /package.json
    /preprocessor.js

I use Windows. Other test types work fine. But when running on windows: npm test, the output is a type error with output likes that:

- TypeError: D:\code\js\flux\node_modules\react\addons.js:
D:\code\js\flux\node_modules\react\lib\React.js:
D:\code\js\flux\node_modules\react\lib\ReactWithAddons.js
D:\code\js\flux\node_modules\react\lib\ReactCompositeComponent.js: Cannot read property 'DEFINE_MANY' of undefined

Could you help me figure out the issue here ?

Look in the example's package.json versus the root package.json. Specifically,

"unmockedModulePathPatterns": ["<rootDir>/node_modules/react"]

React will not tolerate any mockery. I was embarrassed to find it in the docs a couple minutes after my post and the quick response. (Thanks for not calling me out @spicyj).

Thank you for so quick reply.
I'm sorry because i don't understand the rootDir here.
In my case, i have my app directory (flux in this case). My package.json is:
{
"name": "flux",
"version": "0.0.0",
"description": "",
"author": "",
"license": "ISC",
"devDependencies": {
"envify": "^1.2.1",
"es6-promise": "1.0.0",
"gulp": "^3.7.0",
"gulp-browserify": "^0.5.0",
"gulp-concat": "^2.2.0",
"jest-cli": "^0.1.17",
"jquery": "^2.1.1",
"jsdom": "^0.11.1",
"mocha": "^1.20.1",
"react": "^0.10.0",
"react-tools": "^0.11.0",
"reactify": "^0.13.1",
"sinon": "^1.10.3"
},
"scripts": {
"test": "node node_modules/jest-cli/bin/jest.js"
},
"jest": {
"scriptPreprocessor": "D:/code/js/flux/preprocessor.js",
"unmockedModulePathPatterns": ["D:/code/js/flux/node_modules/react"]
}
}

or, i use the instead of absolute path , but the error is the same. Is it Windows error specific ?

Can you push your code to github?

Hi, my code is here: https://github.com/checkraiser/testjest

[popham]

Running

git clone https://github.com/checkraiser/testjest
cd testjest
npm install
npm install jest-cli
./node_modules/.bin/jest

I get

Found 1 matching tests...
PASS  __tests__/CheckboxWithLabel-test.js (8.417s)
1 tests passed (1 total)
Run time: 14.426s

uname -a gives me Linux Device-63FD55 3.15.1-1-ARCH #1 SMP PREEMPT Tue Jun 17 09:32:20 CEST 2014 x86_64 GNU/Linux (64-bit Archlinux). Looks Windows specific, but I don't have a Windows box to verify. Sounds like this warrants a new issue.
