Enzyme's mount() failed when trying to render Animated.View

[ghost]

Hi, I'm trying to test component which has Animated.View, but when I call the enzyme's mount() I'm getting an error TypeError: Cannot read property '__getValue' of undefined

the full stack is: TypeError: Cannot read property '__getValue' of undefined at AnimatedComponent.render (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react-native-mock\build\api\Animated\createAnimatedComponent.js:10:20) at [object Object].ReactCompositeComponentMixin._renderValidatedComponentWithoutOwnerOrContext (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:687:34) at [object Object].ReactCompositeComponentMixin._renderValidatedComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:707:32) at [object Object].wrapper as _renderValidatedComponent at [object Object].ReactCompositeComponentMixin.performInitialMount (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:291:30) at [object Object].ReactCompositeComponentMixin.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:222:21) at [object Object].wrapper as mountComponent at Object.ReactReconciler.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactReconciler.js:39:35) at [object Object].ReactCompositeComponentMixin.performInitialMount (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:297:34) at [object Object].ReactCompositeComponentMixin.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:222:21) at [object Object].wrapper as mountComponent at Object.ReactReconciler.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactReconciler.js:39:35) at [object Object].ReactCompositeComponentMixin.performInitialMount (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:297:34) at [object Object].ReactCompositeComponentMixin.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:222:21) at [object Object].wrapper as mountComponent at Object.ReactReconciler.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactReconciler.js:39:35) at [object Object].ReactCompositeComponentMixin.performInitialMount (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:297:34) at [object Object].ReactCompositeComponentMixin.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactCompositeComponent.js:222:21) at [object Object].wrapper as mountComponent at Object.ReactReconciler.mountComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactReconciler.js:39:35) at mountComponentIntoNode (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactMount.js:103:32) at ReactReconcileTransaction.Mixin.perform (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\Transaction.js:136:20) at batchedMountComponentIntoNode (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactMount.js:124:15) at ReactDefaultBatchingStrategyTransaction.Mixin.perform (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\Transaction.js:136:20) at Object.ReactDefaultBatchingStrategy.batchedUpdates (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactDefaultBatchingStrategy.js:63:19) at Object.batchedUpdates (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactUpdates.js:97:20) at Object.ReactMount._renderNewRootComponent (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactMount.js:277:18) at Object.wrapper as _renderNewRootComponent at Object.ReactMount._renderSubtreeIntoContainer (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactMount.js:354:32) at Object.ReactMount.render (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactMount.js:374:23) at Object.wrapper as render at Object.ReactTestUtils.renderIntoDocument (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\react\lib\ReactTestUtils.js:78:21) at renderWithOptions (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\enzyme\build\react-compat.js:175:26) at new ReactWrapper (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\enzyme\build\ReactWrapper.js:94:59) at mount (C:\Git{xxx}{aaa}\reactNativeSrc\node_modules\enzyme\build\mount.js:21:10) at Context.

Looking at the source, it appears it's a bug that's carried through from day 1. Seems it's trying to access a special prop that isnt there. Although, i'm not sure what it's meant to be, or how it really works

Bump into the same problem here. shallow() works but mount() throws the error.

[RealOrangeOne]

I believe that's something to do with how shallow doesnt render everything. Mount is definitely a better test of this library, although it is only designed to be used with shallow. There's still an error in the codebase though
