RSpec Essentials

By: Mani Tadayon

Overview of this book

This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake. We build up sample applications and their corresponding tests step by step, from simple beginnings to more sophisticated versions that include databases and external web services. We devote three chapters to web applications with rich JavaScript user interfaces, building one from the ground up using behavior-driven development (BDD) and test-driven development (TDD). The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the reader’s ability to make well-informed decisions on their own.

Step 3 – finishing the view

It's been a long chapter, but we are almost done! We now need to incorporate this API into our AngularJS controller and service. Actually, we only need a small addition to the service, a small change to the controller, and no changes at all to the view.

First, in our service static/js/todo_list.js, we'll need to add a method to handle toggleDone:

'use strict';

// define the model to handle the data
var TodoList = function ($http) {
  // ... same as before ...

  // the new method
  store.toggleDone = function(id) {
    return $'/api/v1/todos/' + id + '/toggle_done').then(returnTodos);

  return store;

In static/js/todo_list_controller.js, we'll change the $scope.toggleDone method to use this new TodoList.toggleDone method:

$scope.toggleDone = function(todo) {
    $scope.todos = todos;

That's it! We're ready for the grand finale. Let's run all of our specs and features at once:

It all works...
