0.31.0 - 2023-02-15

New Feature

  • Add extras-testing-tools-effectie with StubToolsFx (#319)

extras-testing-tools-effectie

import cats._
import effectie.core._

trait TestType[F[*]] {
  def foo(n: Int): F[Int]
  def bar(n: Int): F[Int]
}

object TestTypeStub {
  def apply[F[*]: Fx: Monad](f4Foo: => Option[Int => Int], f4Bar: => Option[Int => F[Int]]): TestType[F] =
    new TestType[F] {

      override def foo(n: Int): F[Int] =
        StubToolsFx.stub(f4Foo).map(_(n))

      override def bar(n: Int): F[Int] =
        StubToolsFx.stub(f4Bar).flatMap(_(n))
    }
}

If the stub function is missing, it will be F containing MissingStubException saying where the missing stub is.

For example, the following code

import effectie.instances.ce2.fx._

val testType = TestTypeStub[IO](none, f.some)

testType.foo(n).catchNonFatalThrowable // IO[Either[Throwable, Int]]

results in IO[Either[Throwable, Int]] where Either is Left(MissingStubException) with the information like the following.
