Automating Kotlin data class testing with KSP: Kombinator is an annotation processor for Kotlin that automates the generation of all possible combinations of a data class constructor parameters, facilitating exhaustive testing and reducing human errors in creating test data.
How Kombinator works: by integrating with Kotlin Symbol Processing KSP, Kombinator analyzes annotations at compile time and uses KotlinPoet to generate source code that instantiates each valid combination of constructor parameters, turning manual tests into automated and repeatable tests.
Benefits for testing: broader coverage without extra effort, early detection of edge cases, simplification of parameterized tests, and greater efficiency by integrating these generated artifacts into continuous integration CI CD pipelines to validate regressions on every build.
Practical integration: add the KSP dependency and configure Kombinator for your data classes. The processor takes care of generating object factories and lists of combinations that can be consumed from unit or integration tests, facilitating the use of testing frameworks such as JUnit or Kotest.
Why KotlinPoet and KSP: KSP offers a lightweight and efficient API for processing Kotlin symbols at compile time, allowing the generation of portable and maintainable code, while KotlinPoet provides a fluent API for composing Kotlin source files, ensuring that the generated code is readable and easy to debug.
Typical use cases: validation of domain models, serialization and deserialization testing, business validation checks, and generation of test data for complex integration scenarios where each combination of parameters can reveal hidden failures.
