Detailed description of this workshop
Kotlin Coroutines library is designed to suit common use cases well and has powerful support for testing. This presentation will present typical usages of Kotlin Coroutines in real-life Android and backend projects, as well as it will analyze how those use cases can be properly tested. You will learn what a coroutine is and then explore the most important use cases for using and testing coroutines in real-life projects. The workshop is concentrated on equipping attendees with the essential knowledge to use Kotlin Coroutines in accordance with the best practices.

How to get the most out of this workshop
This workshop assumes that attendees are Kotlin developers or at least use Kotlin fluently. In order to progress smoothly during the workshop, there are a few things we ask you to do in advance:
- Make sure you have Idea IntelliJ installed (The Community Edition is fine.)
- Open this Clone-Project in IDEA IntelliJ as a Gradle project and import using Gradle. Check if it runs fine using the green Play button on Main.kt, but do not solve any tasks for now.
- Extra: Watch the lecture about Kotlin DSL
