6 min readUnit testing views in Ember.js can be done using tools like QUnit or Mocha along with ember-qunit or ember-mocha. Views can be tested by setting up a testing environment using the appropriate tools and writing test cases that check for expected behavior in the views. Unit tests for views often involve checking if the proper elements are rendered, if actions are triggered correctly, and if any computed properties are functioning as expected.

8 min readTo parse nested arrays in a model in Ember.js, you can use computed properties and array methods to access and manipulate the data within the arrays. You can define computed properties that return specific elements or subsets of the nested arrays, and use Array methods such as map, filter, or reduce to iterate over the nested arrays and extract the desired data. By properly defining and manipulating computed properties, you can easily work with nested arrays in your Ember.js models.

This method allows you to search for an object in an array that matches a specific property value.First, you need to get the model data from your component or route using the Ember Data or store service. Then, you can use the findBy() method on the model data array to find the object that matches your criteria.

4 min readTo test ember.js routes, you can use a testing framework like QUnit or Mocha along with the ember-qunit or ember-mocha testing helpers provided by Ember.js.To test routes, you can create unit tests that check if the route transitions correctly, if the correct model is loaded, and if the template renders as expected. You can use the visit() method to simulate visiting a route in your tests and check the behavior using assertions.
