遵循以下答案:Jest -- Mock a function called inside a React Component
我有此测试(尝试模拟fireAnalytics
导入的函数,如下所示:
mytest.test.js
`.import { fireAnalytics } from "@module/js-utils/lib";
jest.mock('@module/js-utils/lib', () => ({ fireAnalytics: jest.fn(() => 'hello!') }))`
`
it('renders component', () => {
const WrappedMyComponent = hoc(Foo);
const props = {};
const wrapper = mount(
<WrappedMyComponent {...props} />
);
const event = {
// target: {
// id: 'test'
// }
};
// simulate click should call `handleInputClick`
wrapper.find('input').props().onClick(event);`
import { fireAnalytics } from "@module/js-utils/lib";
handleInputClick(e) {
// I need to mock this function. But currently the test
goes here and asks for the e.target.id
fireAnalytics({
event: "",
category: "",
action: `Clicked on the ${e.target.id} input`,
label: ""
});
// rest of the code ....
}
TypeError: Cannot read property 'id' of undefined
248 | event: "",
249 | category: "",
> 250 | action: `Clicked on the ${e.target.id} input`,
251 | label: ""
252 | });
