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 9, Resource Management and Extending RxKotlin, right now, and from now on don't forget to test every code you write.
