axios - 基于异常测试axios拦截器逻辑

Question

我在 axios 拦截器中实现了刷新令牌逻辑。简化：

const http = axios.CreateInstance();
http.interceptors.response.use(_ => _, async (error) => {
  try {
    return await http(error.config);
  } catch (e) {
    // this is not called in my test
    location.href = '/logout';
    return Promise.reject(e);
  }
});

在我的测试中，我打电话给

axiosMock.onGet('/token').reply(401);
axiosMock.onGet('/test', undefined, {}).reply(200, {});

try {
  sut.get('/test');
} catch (e) {
  expect(location.href).toBe('/logout');
}

问题是代码并没有在测试中抛出异常，而是在真实代码中。所以测试从http(error.config);
