kotest

Helps write, migrate, and improve Kotlin tests using the Kotest testing framework. Covers test spec styles (FunSpec, DescribeSpec, BehaviorSpec, etc.), assertions (shouldBe, matchers, soft assertions), property-based testing (Arb, forAll, checkAll), data-driven testing, lifecycle hooks, extensions, coroutine testing, project configuration, and multiplatform setup. Use when the user mentions Kotest, kotest matchers, property testing with Arb, Kotest spec styles, shouldBe assertions, Kotlin test framework, or migrating from JUnit/TestNG/Spek to Kotest.
