Jest: React Native Snapshots schlagen mit "TypeError: Cannot read property '_tag' of undefined" für Komponenten fehl, die . enthalten<textinput/>

Fortpflanzen:

1. Ändern Sie https://github.com/facebook/jest/blob/master/examples/react-native/Intro.js , um einen <TextInput /> in render() hinzuzufügen.
2. npm-Test

Ergebnis:

FAIL- Tests /Intro-test.js (0,459s)
● Intro › es wird richtig gerendert

• TypeError: Eigenschaft '_tag' von undefined kann nicht gelesen werden
