View Course Description

Unit testing increases productivity and raises code quality. In this course, author Ron Lisle explains installation and effective use of unit testing tools and techniques for iOS projects, to ensure more stable, functional apps. An example application is provided to demonstrate testing and as the course progresses, developers are shown how to tackle the increasingly complex problems encountered when unit testing iOS development projects.

Topics include:
  • What is unit testing?
  • Comparing the unit testing frameworks for iOS
  • Using unit testing in the refactoring workflow
  • Writing a unit test with OCUnit
  • Writing GHUnit tests
  • Debugging product code with unit tests
  • Using mock objects
  • Testing iOS ViewControllers
  • Testing iOS notifications
  • Testing gesture recognition
iOS Xcode


Hi! I am Ron Lisle and welcome to Unit Testing iOS Applications with Xcode 4. In this course, we will look at unit testing and how to unit test iOS applications. We will use the support built into Xcode 4 called OCUnit and also a couple of open-source unit test frameworks called GHUnit and OCMock. I will start off easy by explaining what unit testing is and how it differs from other types of testing. I'll show you how to install and use the OCUnit support built into Xcode 4, and then we'll see how to add and use the additional unit testing capabilities provided by GHUnit.

Then we will move up to some more advanced techniques including the use of mock objects using OCMock. Finally, we'll look at some of the problem areas when unit testing iOS applications and how these tools can be used to solve difficult testing situations. So let's get started with Unit Testing iOS Applications with Xcode 4.

Q: I'm encountering the following error:

OCMock.h not found

What should I do?
A: This error indicates that you are probably working in a path with spaces. Relocate the exercise files folder to a path with no spaces. See the exercise files movie for more details.
Q: I'm encountering the following error:

GHUnit link error / (_OBJC_CLASS_$_SenTestCase not found)

What should I do?
A: This means the build settings for the GHUnitTests target needs to have the Framework Search Paths changed. Try these steps.

1. Select the GHUnitTests target.
2. Display "Build Settings."
3. Locate the "Framework Search Paths" setting.
4. Delete the existing values.
5. Add the following values:
