Kotest Overview
An introduction to Kotlin’s testing framework.
Kotest is a powerful testing framework written in Kotlin. This page explains how to set up a project.
Kotest provides a variety of testing styles. This page explains the supported testing styles and how to use them.
There are several ways to disable tests. You can hard-code it in the test or disable tests conditionally at runtime.
Isolation Modes control how the test engine creates spec instances for test cases. In other words, they determine how test instances are created for each test case.
When writing effective test code, it is important to manage the lifecycle of each test case. This page explains how to use lifecycle hooks.
Kotest Extensions are extension features that provide various capabilities which can be integrated into the test lifecycle of the Kotest test execution framework.
For effective testing, creating, managing, and cleaning up test data is important. This section looks at how to manage test data with Kotest.
Non-deterministic Testing can help verify software integrity. For example, it can effectively test software systems that include random or unpredictable elements such as parallel processes, external network calls, and access to various system resources.
You can write more robust, higher-quality tests by using Kotest together with the mocking framework mockk and JaCoCo. This page explains mockk, which helps with test isolation and dependency management, and JaCoCo, a code coverage tool that measures how much of a codebase is tested.
Ordering in Kotest is a feature for controlling the order of test execution. It is useful when you want to run tests in a specific order or filter and run tests according to specific conditions.
For effective software testing, writing and managing test cases is important. This section looks at how to write test cases with Kotest.
This page explains how to automatically close resources in Kotest and how to temporarily create files and directories needed for tests.
Kotest Configuration is used to customize and control test execution behavior. It provides many configuration options so users can adjust the test environment as needed.
Sometimes you may want to write a common set of tests and reuse it for specific inputs. In Kotest, you can do this with test factories, which generate tests that can be included in one or more specs.
This page explains how to fail fast in Kotest, how to fail on an empty test suite, and other settings.
