Reactive Programming in Kotlin

By: Rivu Chakraborty

Overview of this book

In today's app-driven era, when programs are asynchronous, and responsiveness is so vital, reactive programming can help you write code that's more reliable, easier to scale, and better-performing. Reactive programming is revolutionary. With this practical book, Kotlin developers will first learn how to view problems in the reactive way, and then build programs that leverage the best features of this exciting new programming paradigm. You will begin with the general concepts of Reactive programming and then gradually move on to working with asynchronous data streams. You will dive into advanced techniques such as manipulating time in data-flow, customizing operators and provider and how to use the concurrency model to control asynchronicity of code and process event handlers effectively. You will then be introduced to functional reactive programming and will learn to apply FRP in practical use cases in Kotlin. This book will also take you one step forward by introducing you to Spring 5 and Spring Boot 2 using Kotlin. By the end of the book, you will be able to build real-world applications with reactive user interfaces as well as you'll learn to implement reactive programming paradigms in Android.

Summary


So, in this chapter, we learned about testing in Kotlin. We started with the benefits of testing and then moved on to testing in Kotlin, using JUnit and Kotlin-test.

As we got some hands-on testing experience in Kotlin, we gradually moved to testing in RxKotlin, we learned a few technique to test RxKotlin and learnt about the super-convenient testing tools that RxKotlin provides for us.

As we have built a strong base of knowledge in RxKotlin, in the next chapter—Chapter 9,Resource Management and Extending RxKotlin we are going to discuss some advanced topics. We will discuss managing resources—how to free allocated memory and prevent memory leaks. We will also learn to create our own custom operators, which can be chained in the RxKotlin logic just like those predefined operators.

So, what are you waiting for? Get started on Chapter 9Resource Management and Extending RxKotlin, right now, and from now on don't forget to test every code you write.
