object MatcherProducers extends MatcherProducers
Companion object that facilitates the importing of MatcherProducers
members as
an alternative to mixing it in. One use case is to import MatcherProducers
's members so you can use
MatcherProducers
in the Scala interpreter.

convertToComposifier[T](f: (T) ⇒ Matcher[T]): Composifier[T]
Implicit conversion that converts a function of
T => Matcher[T]
to an object that hascomposeTwice
,mapResult
andmapArgs
methods.Implicit conversion that converts a function of
T => Matcher[T]
to an object that hascomposeTwice
,mapResult
andmapArgs
methods.The following shows how this trait is used to compose twice and modify error messages:
import org.scalatest._ import matchers._ import MatcherProducers._
val f = be > (_: Int) val g = (_: String).toInt
// f composeTwice g means: (f compose g) andThen (_ compose g) val beAsIntsGreaterThan = f composeTwice g mapResult { mr => mr.copy( failureMessageArgs = mr.failureMessageArgs.map((LazyArg(_) { "\"" + _.toString + "\".toInt"})), negatedFailureMessageArgs = mr.negatedFailureMessageArgs.map((LazyArg(_) { "\"" + _.toString + "\".toInt"})), midSentenceFailureMessageArgs = mr.midSentenceFailureMessageArgs.map((LazyArg(_) { "\"" + _.toString + "\".toInt"})), midSentenceNegatedFailureMessageArgs = mr.midSentenceNegatedFailureMessageArgs.map((LazyArg(_) { "\"" + _.toString + "\".toInt"})) ) }
"7" should beAsIntsGreaterThan ("8")The last assertion will fail with message like this:
"7".toInt was not greater than "8".toInt
- T
the type used by function
f
- f
a function that takes a
T
and return aMatcher[T]
- returns
an object that has
composeTwice
,mapResult
andmapArgs
methods.
