typelevel/munit-cats-effect

This system is a Scala library that integrates the MUnit testing framework with the Cats Effect ecosystem. It provides a base suite and specific assertion methods for validating IO and SyncIO effects, along with fixture support for managing resource lifecycles in tests. The library ensures binary compatibility across multiple Scala and Cats Effect versions.

This change introduces the initial build setup and documentation for the munit-cats-effect library, which integrates MUnit with cats-effect. The repository now includes a \.scalafmt.conf\ file configured for Scala 2.13 Source 3 compatibility and an updated \.gitignore\ that excludes IDE and build artifacts (such as \.metals\, \.bloop\, and \.bsp\). The \README.md\ has been significantly expanded to document the library's features, including support for \IO\ and \SyncIO\ assertions, suite-local fixtures, and binary compatibility for both Cats Effect 2 and 3 across Scala 2.12, 2.13, and 3.

This change introduces the \CatsEffectSuite\ base class and supporting traits (\CatsEffectAssertions\, \CatsEffectFixtures\, \CatsEffectFunFixtures\) for testing Cats Effect programs. Users can now write tests that return \IO\ or \SyncIO\ values, which are automatically transformed into Futures by the framework. The suite provides specific assertion methods like \assertIO\, \assertSyncIO\, \interceptIO\, and \interceptMessageIO\ for validating effect results. It also includes fixture support via \ResourceFunFixture\ and \ResourceSuiteLocalFixture\ for managing resource lifecycle in tests. Additionally, it introduces \munitIOTimeout\ to configure graceful cancellation of \IO\-based tests, with a fallback \munitTimeout\ for overall test execution limits. The implementation also includes internal nesting checks to prevent common mistakes like returning \IO\[IO\[\_\]\]\.

A new \ResourceFixture\ object and \IOFixture\ abstract class have been added to the \munit.catseffect\ package, providing \testLocal\ and \suiteLocal\ methods. These allow users to easily integrate Cats Effect \Resource\[IO, A\]\ instances into Munit tests, automatically handling resource allocation and cleanup at the test or suite level, and throwing a specific exception if the fixture is accessed before instantiation.

Added new test suites in core/src/test to verify the Cats Effect integration, including CatsEffectAssertionsSpec for assertIO/interceptIO functions, CatsEffectAssertionsSyntaxSpec for extension methods like assertEquals and mapOrFail, CatsEffectFixturesSpec for resource lifecycle management, CatsEffectFunFixturesSpec for functional fixtures, CatsEffectSuiteSpec for timeout and nested effect handling, and ExampleSuite demonstrating usage patterns.
