Installing Data fixtures

Fixtures are fake data that allow testing of an app without having to do the tedious task of manually creating data after each install. They are useful for automated testing processes and make it easier for a new developer to start working on our projects.

Note

Any application should be covered with automated tests. The blog app we are building is covered by Behat (http://behat.org/) tests. They are provided in downloads available on the Packt website.

Doctrine has an extension called Data Fixtures that ease fixtures creation. We will install it and use it to create some fake blog posts.

Type this command in the root of the project to install Doctrine Data Fixtures through Composer:

  php composer.phar require doctrine/data-fixtures:1.0.*

The first step to using Doctrine Data Fixtures is to create a fixture class. Create a file called LoadPostData.php in the src/Blog/DataFixtures directory as shown in the following code:

  <?php

  namespace Blog\DataFixtures;

  use...
