Hello, Good Afternoon, I had written one consumer test for `200` status and it worked well for me, my next task is to validate `401 Unauthorised` state, but my consumer test is failing <https://codeshare.io/wnEOZD>, could anyone point me to right direction.

Does your http client throw an error on non 2xx status codes?

If so please read <https://jestjs.io/docs/asynchronous|https://jestjs.io/docs/asynchronous>

Sample code 

await expect(fetchData()).rejects.toMatch('error');

My test fails with this line `Request failed with status code 401`

I assume the promise has rejected as the provider is setup to return a 401

await api.getUserSettingsStatus()

I feel, it gets the status `401` but does not match the body

```async getUserSettingsStatus() {
    return axios
      .get(this.withPath("/api/1/user"), {
        headers: authHeader,
      })
      .then((r) =&gt; {
        return r.data;
      });
  }```

In your test you must catch the failing promise and confirm that it meets the expectations of the calling code

```async getUserSettingsStatus() {
    return axios
      .get(this.withPath("/api/1/user"), {
        headers: authHeader,
      })
      .then((r) =&gt; {
        return r.data;
      })
      .catch((error) =&gt; {
        if (error.response.status === 401) {
          return Promise.resolve(error.response.data);
        }
      });
  }```

Your code has a bug in that it will swallow errors- you should re-throw an exception if the error is not what you were expecting

yeah I changed it later, thanks <@UAPSFV5QV>

Given this question was literally asked in the previous post and does come up a bit, I’ve created a little guide in our troubleshooting doc for this: <https://github.com/pact-foundation/pact-js/blob/master/docs/troubleshooting.md#how-do-i-test-negative-scenarios-such-as-400>
