Review the solution to testing the profile and logout endpoints.

Challenge solution

Let's review the code for each task of the challenge exercise.

Follow the steps below to import the challenge collection:

Logged in profile request

The screenshot below illustrates the three test cases to verify the response data, status code, and authentication token:

Press + to interact
pm.test("given authorized user, returns 200 status", () => {
  pm.response.to.have.status(200);
});
pm.test("given authorized user, returns expected response data", () => {
  const RESPONSE = pm.response.json();
  const USER = pm.collectionVariables.get("username");
  pm.expect(RESPONSE['user']).to.eql(USER);
});
pm.test("given authorized user, returns 200 status", () => {
  const TOKEN = pm.cookies.get('token');
  pm.expect(TOKEN).to.be.a('string');
});
