testing components with enzyme

Hi guys, Thanks for great work in NativeBase. My project looks like this: react-native 0.51.0 native-base 2.3.5 emzyme 3.3.0 jest 20.0.4

I’m having difficulty using enzyme to render my components. What I’m trying to achieve is to render a component, which has included a number of NativeBase components. I’m encountering several warnings for instance:

Warning: <Text /> is using incorrect casing. Use PascalCase for React components, or lowercase for HTML elements.

and

Warning: React does not recognize theallowFontScalingprop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercaseallowfontscalinginstead. If you accidentally passed it from a parent component, remove it from the DOM element. in Text in Text (at Text.js:30) in Text in Styled(Text)

My guess is that enzyme was not able to determine correct environment and thinks we are in React. any hints what should I do to fix this?

Having the same issue. Apparently the tests run good, but the warning does appear.

Following solved the problem for me

it('has appropriate title', () => {
    const wrapper = shallow(<MyHeader title="title123" />);
    expect(wrapper.contains(<Title>title123</Title>)).toBe(true);
});
