v1.0.0-M3

• Updated Cats Effect to 3.0.0-RC3

v1.0.0-M2

This is the first release provided under the org.typelevel groupId!

• Updated to Cats Effect 3.0.0-RC2
• Added support for Scala 3.0.0-RC1
• Removed support for Scala 3.0.0-M3

v0.5.2

• Added support for Scala 3.0.0-RC1
• Dropped support for Scala 3.0.0-M3

v0.5.1

• Dropped support for Scala 3.0.0-M2
• Added support for Scala 3.0.0-M3
• Updated several dependencies to minor version bumps

v1.0.0-M1

• Updated to Cats Effect 3 (version 3.0.0-M5 at present)
• Added support for ScalaJS
• Rewrote Specs2 support to be fully asynchronous
• Removed scalatest-scalacheck support (for now)
• Removed µTest support due to ongoing release issues (the µTest artifacts are frequently released Java 11-only, which is problematic)
• Refactored the API to be more in line with what should be expected within the Cats Effect 3 framework
• Added UnsafeRun abstraction. This typeclass must be implemented for any datatype which is intended to be used with cats-effect-testing. At present, the only implementation is for IO, which also implies a dependency on Cats Effect core. This will be refactored before 1.0.0 goes final to allow for support for other datatypes.

v0.5.0

• Updated Cats Effect to 2.3.0
• Updated minitest to 2.9.1
• Dropped support for Scala 3.0.0-M1 and added M2 (forced by µTest and minitest)
• Updated scalatest to 3.2.3
• Updated scalacheck to 1.15
• Updated the CatsResource mechanism in scalatest to be compatible with scalatest's async functionality (@Grogs)

v0.4.2

This is the first release with full support for Dotty 0.27.0-RC1 and Scala 3.0.0-M1. Unfortunately, most of the supported test frameworks have still not released any recent-Dotty-compatible versions. At present, only the Specs2 module has been released, but it's likely that the others could be soon.

• Updated Specs2 to 4.10.5
• Updated ScalaCheck to 1.15.1
• Updated ScalaTestPlus-ScalaCheck to 3.2.2.0
• #54 – Make ExecutionContext available when mixin CatsIO trait (@tovbinm)
• Updated ScalaTest to 3.2.2
• Updated µTest to 0.7.5
• #84 – README improvements (@mcanlas)

v0.4.1

• Updated µTest to 0.7.4
• Updated ScalaTest to 3.1.2
• Updated Specs2 to 4.10.0
• Support for Resource-based tests in ScalaTest (#72, @custommonkey)
• Support for Resource based tests in Specs2 (#69, @ChristopherDavenport)
• Abstracted testing style in ScalaTest to allow use with different styles (#43, @endertunc)

Thank you, everyone!

v0.4.0

• Moved everything under cats.effect.testing top level package, to avoid import conflicts (thanks @Slakah!)
• ScalaTest 3.1.0 support
• Direct ScalaCheck property support (by @iRevive)

0.3.0

Continuing to flesh out our feature-set. Major changes:

• The Specs2 support is now generalized to any Effect, allowing convenient syntax for testing Monix Task and ZIO in addition to cats-effect's own IO. The CatsEffect trait represents the generalized version, while CatsIO is the mixin to use when testing with cats.effect.IO.
• ScalaTest support is here!

Remember that this is an 0.x release, so no particular compatibility guarantees are made with anything outside the 0.3.x major/minor pair. We'll be moving to stabilize things more in the future.
