Appendix E. Unit Testing

In this appendix, we show you how to add unit tests to your project. By adding unit testing support, you'll be able to write tests for your methods. These tests will be added as a dependency on the building of your application. This will result in the tests being run before actually building your application.

In the following, we walk you through a step-by-step process for adding unit testing. We use a simple Employee class for demonstration purposes.

Adding a Unit Test Target

In this section, we show you how to create a unit test target in your project. Later, we will make our main target dependent on this unit test target, thus making sure that the unit tests are executed before building our target.

Right-click on Targets node in Groups & Files. Select Add > New Target as shown in Figure E.1.
