and combinator behaves differently for MatchResult and Result under MustThrowExpectations

[kneisslm]

Environment: Specs 2 4.20.5, Scala 2.12

See example below. I'd expect that both examples fail. In practice only the first (eg1) fails.

Specification

import org.specs2.Specification
import org.specs2.execute.Result
import org.specs2.matcher.MustThrownExpectations

class ResultAndSpecification extends Specification with MustThrownExpectations {

  def is = {
    s2"""
Combining MatchResult and Result should behave like combining MatchResult with MatchResult in MustThrownExpectations.

I'd expect that both examples fail.

  - two MatchResults $eg1
  - MatchResult and Result $eg2
"""
  }


  def eg1 = {
    (ok and ko)

    ok
  }

  def eg2 = {
    ok and (ko: Result)

    ok
  }
}

Output

[info] ResultAndSpecification

Thanks for reporting this issue @kneisslm. It is fixed in 4.20.8.
