SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Kotlin developers often lack a single, expressive framework for writing tests across platforms; Kotest provides a unified approach to spec-style and property-based testing, reducing boilerplate and improving test quality.

Core Features & Use Cases

  • Spec styles (FunSpec, DescribeSpec, ShouldSpec, and more) for flexible test structure.
  • Multiplatform support (JVM, Kotlin/JS, Kotlin/Native, Wasm) enabling cross-platform test suites.
  • Data-driven testing and property testing with a first-class API for robust validation across inputs.

Quick Start

Install Kotest dependencies and run tests to verify results.

FAQPage Schema
How do I write expressive Kotlin tests across multiple platforms?▼

Spec-style testing structures test suites using descriptive patterns like FunSpec, DescribeSpec, and ShouldSpec, reducing boilerplate and improving test readability for Kotlin developers across different platforms.

What is the best way to run data-driven and property-based tests in Kotlin?▼

The best way to run data-driven and property-based tests in Kotlin is using Kotest, which offers a first-class API for robust validation across multiple inputs within a unified multiplatform framework.

Does Kotlin multiplatform testing support Wasm and Kotlin/Native environments?▼

Yes, Kotlin multiplatform testing with Kotest supports Wasm and Kotlin/Native environments, allowing you to execute spec-style and property-based tests seamlessly across JVM, Kotlin/JS, Kotlin/Native, and Wasm projects.

How do I configure a Gradle project for multiplatform spec-style testing?▼

To configure a Gradle project for multiplatform spec-style testing, you need to add the Kotest dependencies to your build script and configure a test runner to execute the specs across your targeted platforms.

Why use a unified Kotlin testing framework instead of separate platform-specific tools?▼

Using a unified Kotlin testing framework like Kotest eliminates the need for separate platform-specific tools, reducing boilerplate and improving test quality by providing a consistent spec-style and property-testing API across all platforms.
