Not that I know of.
I know ecosystem is usually represented at https://github.com/lauris/awesome-scala#testing (to which we should add weaver at some point tbh)
That repo is such an awesome rabbit hole - I spent hours finding a random library from 2015 and playing with it
all current main Scala test libraries
It's also a moving target - it's like saying "comparing all json libraries" :D once you finish a writeup you need to add a new one
There was an article a few weeks ago that aimed at doing that : https://ivan-kurchenko.medium.com/testing-with-scala-libraries-landscape-61b4c6403455
It was focused on good old unit-testing, and didn't talk about weaver / zio-test / distage-testkit
distage-testkit](https://izumi.7mind.io/distage/distage-testkit) - which has all the features of weaver, plus docker support and principled cross-suite resource sharing (no static objects and no global state) and appeared earlier too.
I'm not sure what Oli had in mind, but it's probably mostly for integrating new functionality into weaver's output rendering - so it's a fairly obscure feature which is better served by examples :)
hoping to produce one relatively soon.
I mean, everything's possible ... but I don't think it's something I'd want to maintain.
Regarding the implementation, the difficulty has to do with finding the test classes without the kind of metadata that is typically produced by build tools. I don't know how specs2 does it.
The abstract standalone runner you found in the weaver codebase gives you an example of how you can run suites and collect their results once you have the instances.
We've just released 0.6.3/0.7.3 with Scala 3 final 🎉 The RC-chasing is over :)
No other changes in the release apart from some upgrades.
expect to work with their DenseMatrix.

Hi, I am using expect method(Expectations.Helpers) in weaver.

Hi everyone!
I'm using weaver 7.0.4, Scala is 3.0.1.
build.sbt:
testFrameworks := Seq(new TestFramework("weaver.framework.CatsEffect"))I'm willing to use weaver with a compound effect:
final case class RaisedError(error: Throwable, pos: Position, errorId: String)
final case class LogContext(traceId: String, extra: Map[String, String])
type WithLogContext[F[_], A] = Kleisli[F, LogContext, A]
type WithError[A] = EitherT[IO, RaisedError, A]
type Eff[A] = WithLogContext[WithError, A]
trait AppSuite extends MutableFSuite[Eff] {
abstract class CatsEffect extends SimpleMutableIOSuite {
val translate = new cats.arrow.FunctionK[Eff, cats.effect.IO] {
def apply[A](fa: Eff[A]): IO[A] = /* translate to IO */
}
override def spec(args: List[String]): fs2.Stream[cats.effect.IO, TestOutcome] =
self.spec(args).translate(translate)
}
}
// this object is not discovered by the runner
object MySuite extends AppSuite {
test("some test") { ... }
}
// this object is discovered
object MySuiteCE extends MySuite.CatsEffectUnfortunatelly, I need to expose the CatsEffect object (object MySuiteCE extends MySuite.CatsEffect). Otherwise the suite is not discovered by weaver.framework.CatsEffect.
Can I reduce the boilerplate somehow?
sharedResources in terms of Eff, and where you're wanting to inject the log context
I tried to implement a separate method def testF(...)(eff: Eff[Expectation).
I faced several issues:
1) I need dual constructor for my resources. E.g. def loadApp[F[_], G[_]](config: Config): F[Application[G]]). Where F = IO, and G = Eff.
2) Scalacheck checkers do not work out of the box. forall offers only IO methods (which is expected).
