Description

Unit Testing is a must-have skill and this video course is about Unit Testing Swift code. If you take this video course, you will learn how to follow a Test Driven Development process to implement a feature for an iOS mobile app built with Swift.   This video course starts with Unit Test basics and continues with a very practical set of lessons that demonstrates how to follow a Test-Driven process to implement the User Signup feature in the Model View Presenter mobile app.By the end of this video course, you will have a very clear understanding of how to write Unit Tests and UI Tests for your Swift mobile application, and you will be able to test even very complex Swift code. If you are a freelance developer you might postpone learning how to unit test iOS app for some time. But if you are planning to join a bigger team, then unit testing is a must-have skill for you to be able to work on important app features.Have a look through the curriculum of this course to see what it covers. Watch a few sample video lessons. And if you have questions, I am always here to help you.
