Upgrading tests from old style/version

[rbscgh]

Im trying to convert my tests that were on specs2 4.20 scala 2.13 and with specs-mock

to latest with scala3 and scalamock..

im a little confused about the layout of tests.. previously we would build a trait context that extended scope and build ontop of this context many test cases but scope no longer seems available.

previous test:

  trait Context extends Scope {
    // mocks
    // vals

    def result: ???
  }

  "my test" >> {
    "run with this context" in new Context {
      result ==== 1
    }
  }

first refactor:

  trait Context extends MockContext {
    def result: ???
  }
  "my test" should {
    "run with this context" in new Context {
      result === 1 // this doesnt compile
    }
  }

the error is exactly that it cannot convert the context to a result.

/* missing */ summon[UnitSpecification.this.Context => org.specs2.execute.Result]

but if i do something like:

  trait Context extends MockContext {
    def result = 1
  }
  "my test" should {
    "run with this context" >> {
      val c = new Context {}
      c.result === 1
    }
  }

this compiles however this feels incredibly cumbersome and falls over quickly on more complex test setups. surely im missing something ?

Thanks in advance!

I might have thrown the baby out with the bath water...

1. Scope was related with some Before/After traits that were using DelayedInit with disappear with Scala 3.
2. Since Scope involves some exception throwing inside the body of a trait definition, it has to be really well implemented otherwise the whole specification fails to be instantiated.

That being said I understand how it can be syntactically useful so maybe it is time to re-introduce it.
You can use that code in the meantime:

import org.specs2.execute.*

trait Scope

object Scope:
  given scopeAsResult[S <: Scope]: AsResult[S] = new AsResult[S]:
    def asResult(t: =>S): Result = AsResult.safely { Result.resultOrSuccess(t) }

// Example
class MySpec extends mutable.Specification:
  "e1" in new MyScope:
     someValue === 1

trait MyScope extends Scope:
  val someValue: Int = 1

Then , please make a PR if you have a bit of time, or I will incorporate it in an upcoming release.

For some context, here were my thoughts when I started thinking about the Scala 3 migration: https://medium.com/@etorreborre_99063/becoming-reasonable-361d7f674ee0

Well, I decided to go ahead and do it. This version will be available as 5.5.2.
