我有一个要尝试测试的DialogBox组件。我正在尝试在DialogBox中设置子组件(TextInput)的'value'属性。我已经尝试了几乎所有内容,但似乎没有任何效果。有人可以帮我吗?
upload_to
console.log(obj.html())转储为:
test('input type returns a text', () => {
const okPressFunction = jest.fn()
const obj = (
shallow(
<DialogBox
title='random title'
message={lorem}
type='input'
isVisible
onOkPress={okPressFunction}
onRequestClose={noop}
/>
)
)
// obj.dive().find('TextInput').setProps({ value: 'hi' })
// obj.update()
// console.log(obj.dive().find('TextInput').prop('value'))
obj.find('TextInput').simulate('change', {
target: { value: 'hello' },
})
obj.update()
console.log(obj.dive().find('TextInput').prop('value'))
})
})
我正在测试一个ui测试方案,其中用户首先在文本Input中输入一个值,然后单击最后一个按钮(“操作”),然后像回调函数一样返回输入值。但是,首先我需要设置文本Input的值。我有一份通过官方文档获得的信息,还有许多没有有意义帮助的线程。
对话框代码:
<Component
transparent={true}
animationType="fade"
visible={true}
onRequestClose={[(Function: noop)]}
hardwareAccelerated={false}
>
<View
style={{
backgroundColor: "#33333340",
width: "100%",
height: "100%",
justifyContent: "center",
alignItems: "center",
}}

<View

This post建议避免使用simulate
并直接调用道具。
应用该方法:
test('input type returns a text', () => {
const okPressFunction = jest.fn()
const obj = (
shallow(
<DialogBox
title='random title'
message={lorem}
type='input'
isVisible
onOkPress={okPressFunction}
onRequestClose={noop}
/>
)
)
obj.find('TextInput').props().onChangeText('hello');
obj.find('Button').at(1).props().onPress();
expect(okPressFunction).toHaveBeenCalledWith('hello'); // SUCCESS
});
