Utilizing Angular within a Protractor Test

Is there a way to access Angular in Protractor tests similar to unit testing?

My specific scenario involves a service that manipulates text, and I need to use this service within the test script. I am aware of the addMockModule method in Protractor, but I'm unsure how to utilize it for this situation.

Any assistance would be greatly appreciated!

Answer №1

One of the key features in Protractor is the evaluate() function, which allows you to find an element in the DOM and then execute a specified expression.

For instance, if you're looking to count the number of todos on the http://angularjs.org/ website (located under Add Some Control), you can follow these steps:

Begin by opening the element explorer in Protractor

./node_modules/protractor/bin/elementexplorer.js
browser.get('http://angularjs.org/')
element(by.model('todoText')).evaluate('todos.length').
  then(function(count) {
    console.log(count)
  });

This will output a count of 2

Another option is to use executeAsyncScript

browser.executeAsyncScript(function(callback) {
  // In this example, we're utilizing document.body, but your application may be nested within another element.
  var service = angular.element(document.body)
      .injector()
      .get('myService');
  service.query({}, function(data) {
    callback(data);
  });
}).then(function (output) {
  console.log(output);
});
