在下面的代码中,我正在使用React,Jest和Enzyme来确认传递到组件中的prop具有已知值。被测组件由受控的INPUT元素组成。当我将其中一个测试值更改为FAIL(失败)时,“ Received”(接收到的)值将以未定义而不是错误的值返回。我不知道为什么。我测试输入元素的值不正确吗?
import React from "react"
import { shallow, mount, render } from 'enzyme';
import { MyAddressForm } from "../components/addressForm"
const testText = "fieldValue"
const testObject = {
firstName: {testText},
lastName: 'Smith'
}
const wrapper = shallow(<MyAddressForm shipTo={testObject} />)
var fields = []
for (var field in testObject) {
if (testObject.hasOwnProperty(field)) {
fields.push(field)
}
}
var theTest = (fieldName) => {
let selector = `input[name="${fieldName}"]`
expect(wrapper.find(selector).prop('value').text).toEqual(testText)
}
test.each(fields)(
'%s',
fieldName => theTest(fieldName)
)
答案 0 :(得分:0)
因为将firstName设置为对象,而不是testText的值!
正确的测试功能应为:
var theTest = (fieldName) => {
let selector = `input[name="${fieldName}"]`
expect(wrapper.find(selector).prop('value')).toEqual(testText)
}
