Top 7 Kotlin Assertion Projects

Kotest

7 3,949 8.5 Kotlin

Powerful, elegant and flexible test framework for Kotlin with additional assertions, property testing and data driven testing

Project mention: Best practices for Unit Testing Android Apps with Mockk, Kotest and others | dev.to | 2023-05-10

As a matter of fact, in the previous examples, we have shifted a bit away from the TDD standards in the meaning that we test not only the operability of our code, but rather check if the code runs according to certain specifications (Given/When/Then). These specifications are our tests, and the syntactic sugar in the form of the possibility to give clear names to the tests using DisplayName and the grouping of the tests by a set of similar attributes helps us clearly formulate these specifications. There is an entire family of frameworks in different languages that allow us to create such specifications: for Java it is Spock, for Ruby—RSpec, and for Kotlin—Spek and Kotest frameworks. Below, I will go into more detail about them.
strikt

2 493 8.6 Kotlin

An assertion library for Kotlin

Project mention: Kotlin assertion libraries - JUnit, Hamkrest and Strikt | /r/Kotlin | 2023-01-06

In this episode we first look at improving our use of JUnit, using kotlin.test to improve type safety, and assertAll to make multiple checks on the same subject. Then we look at Hamkrest (https://github.com/npryce/hamkrest), a Kotlin reimplementation of the classic Hamcrest, before settingly on Strikt (https://strikt.io/) for our fluent assertions.
