我创建了一个使用商店中的 getter 的全局守卫。
我试图从商店模拟一些吸气剂以进行测试。问题是嘲笑
不起作用。
// router/index.ts
export function beforeEach(to: any, from: any, next: any) {
const isLoggedIn = store.getters.isLoggedIn();
const isGuest = to.matched.some((record: any) => (record.meta.guest));
if (isLoggedIn) { // isLoggedIn is always false
if (isGuest) {
next('/');
}
}
}
}
//router/index.spec.ts
describe('shoud test routing functionality', () => {
it('should redirect to / when isLoggedIn is true and IsGuest is true', () => {
// given
jest.mock('@/store', () => ({
getters: {
isLoggedIn: jest.fn().mockImplementation(
() => true, // <----------- this value is always false
),
},
}));
// even this one does not work
// jest.spyOn(getters, 'isLoggedIn').mockImplementation(() =>
// ()=> true);
const to = {
matched: [{ meta: { guest: true } }],
};
const next = jest.fn();
// when
beforeEach(to, undefined, next);
// then
expect(next).toHaveBeenCalledWith('/');
});
})
我从这个例子中得到启发。
