How to test React Native Button in Jest?












0














How could I test a press in react native? (react-native-elements)
So the code I want to test is:



<ListItem
containerStyle={styles.container}
titleContainerStyle={styles.title}
chevronColor={'#70be1d'}
rightIcon={{name:'check'}}
key={id}
title={name}
hideChevron={!checked}
onPress={ ()=>onMeasureRowPressed(id) }
/>

          You can approach this in two different ways, direct or indirect.



          direct:



           const wrapper = shallow(< ListItem />);
          const instance = wrapper.instance();
          expect(wrapper.state('pressedRow')).toBe('');
          instance.onMeasureRowPressed('1234');
          expect(wrapper.state('pressedRow')).toBe('1234');


          indirect:



          const wrapper = shallow(<ListItem />);
          expect(wrapper.state('pressedRow')).toBe('');
          wrapper.find('ListItem').simulate('keyPress', {key: 'foo'});
          expect(wrapper.state('pressedRow')).toBe('1234');
