What is the best way to structure my protractor scenarios for effectively validating HTTP response errors?

My current setup involves using protractor to test the functionality of my Angular client, while the server is implemented using Python Google App Engine.

In order to enhance my protractor test, I am looking to include an assertion on the http response generated by a POST request triggered by the click of a form button. Here is an example of what I am trying to achieve:

  describe('Pointless Form Post Test', function() {
  beforeEach(function() {
      browser.get('/myform'); 
  });

  it('should populate a form, submit it, and handle the response without errors', function() {
      element(by.model('form_summary')).sendKeys('Some input text');
      element(by.model('form_details')).sendKeys('Lots of detailed text');
      element(by.id('formBtn')).click();
              --> ASSERTION NEEDED FOR HANDLING HTTP 500 ERROR RESPONSE <
  })
});

Is there a way to validate the response received from the server after clicking the form button?

On a side note, I am starting to question if my approach to End-to-End testing with protractor aligns with its intended scope. However, I believe this functionality is crucial for my testing needs. While writing a test targeting my POST handler, I discovered that the server was returning 500 errors (due to a server bug). I am hopeful that protractor can help catch and handle such issues.

Answer №1

With Protractor, you have the ability to access the browser console's output. This means you can analyze the output and look for any errors, such as a 500 error.

For a real-life example, check out this case shared by someone else:

https://github.com/juliemr/protractor-demo/blob/master/howtos/browserlog/spec.js

Whether this is the proper use of Protractor is up for debate. As mentioned by another user, it may be more effective to showcase the error in your user interface and then use Protractor to test that the error display works correctly, rather than focusing solely on the error itself.
