Integration tests are used to validate a larger section of your code. This is the foundation of all of our testing so you want to write many unit tests to cover all your functions. Unit tests are short, simple, and run very quickly. This is done by inputting variables to the function and checking that they return the expected output. Unit tests help verify a single piece of code, generally a function. Unit tests are the foundation of our pyramid. The pyramid model approach to testing helps to strike a balance between thoroughness, quality and execution speed. We're going to start with a summary of how you should consider planning out the automation test suite of any project.

You can also use test to codify requirements, meaning you make test for expected behaviors for your app, and further work by you and your team can be qualified against these expectations.

Testing is an important step of developing any project which can help you find bugs in your source code. XCTest is the automation testing framework provided in Xcode with built-in support to help you set up and execute your tests. Finally, Ethan will show you applications of XCTest with continuous integration. Then, Stuart will tell you about the test plans feature. In today's session, we'll start with an introduction to testing in XCode with XCTest. My name is Ana Calinov and I'll be presenting along with my colleagues, Stuart Montgomery and Ethan Vaughan. Good morning, and welcome to Testing in Xcode.
