Kotest provides various matchers for use with Konform. They can be used in your tests to assert that a given object is validated or fails validation.
To use these matchers add
implementation 'io.kotest:kotest-assertions-konform-jvm:<version>' or
implementation 'io.kotest:kotest-assertions-konform-js:<version> to your build.
Let's start with a basic data class:
Then given a

We can test that instances pass validation like this:
And we can test that instances fail validation with specific error messages like this:
|Asserts that the validation is valid for the given value|
|Asserts that the validation is invalid for the given value|
|Asserts that the validation is invalid for the given value, and then, runs the block with invalid value|
