A hands-on workshop to learn how to make your applications robust and refactoring easier. Enhance the trust on your code while learning the tricks of the trade.

Overview

Very likely you have been told about unit testing your code before. You may already know the theory and you would want to give it a try. But it is hard to walk this path alone since the first tests are also the hardest.

This hands-on workshop takes a different approach. Learn the concepts and use the de facto standard frameworks (JUnit 5 and XCTest) to write actual tests of realistic applications.

Reach the top of the Unit Test Mountain!

Learn how to

  • What are Unit Tests and how to write them

  • How to simplify the tests and have Clean tests too

  • When and how to use Test Doubles

  • What is TDD and how to practice it

  • How to unit test everything in your app, including the views

  • Make the quality of your code something better than a matter of faith!

Audience

This course is intended for Android mobile app developers who would like to improve the way they build their products. Attendees should have at the very least 6 months of experience developing Android applications (1 year preferred) and should be familiar with Kotlin development, know object-oriented programming and what a design pattern is.

A Java version is also available.
