If you are using Jest 0.9+ with enzyme and using Jest's "automocking" feature, you will need to mark
react and enzyme to be unmocked in your package.json
:
/* package.json */
"jest": {
"scriptPreprocessor": "<rootDir>/node_modules/babel-jest",
"unmockedModulePathPatterns": [
"react",
"enzyme"
],
"moduleFileExtensions": [
"json"
]
}
If you are using a previous version of Jest together with npm3, you may need to unmock more modules.
