kotlin.test provides a set of utility functions for performing assertions in tests, independently of the test framework being used. The functions are defined as top-level functions in the package.
The test framework is abstracted through the [Asserter] class. A basic [Asserter] implementation is provided out of the box. The kotlin-test-junit module provides an implementation of [Asserter] on top of JUnit. Note that the class is not intended to be used directly from tests.
