How to mock window.location.href with Jest + Vuejs?(如何用 Jest + Vuejs 模拟 window.location.href?)
问题描述
目前,我正在为我的项目实施单元测试,并且有一个包含 window.location.href 的文件.
Currently, I am implementing unit test for my project and there is a file that contained window.location.href.
我想模拟这个来测试,这是我的示例代码:
I want to mock this to test and here is my sample code:
it("method A should work correctly", () => {
const url = "http://dummy.com";
Object.defineProperty(window.location, "href", {
value: url,
writable: true
});
const data = {
id: "123",
name: null
};
window.location.href = url;
wrapper.vm.methodA(data);
expect(window.location.href).toEqual(url);
});
但我收到此错误:
TypeError: Cannot redefine property: href
at Function.defineProperty (<anonymous>)
我尝试了一些解决方案,但没有解决.我需要一些提示来帮助我摆脱这个麻烦.请帮忙.
I had tried some solutions but not resolve it. I need some hints to help me get out of this trouble. Plz help.
推荐答案
你可以试试:
global.window = Object.create(window);
const url = "http://dummy.com";
Object.defineProperty(window, 'location', {
value: {
href: url
}
});
expect(window.location.href).toEqual(url);
