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.

Type Members

  1. class Composifier [T] extends AnyRef

    Class used via an implicit conversion that adds composeTwice, mapResult, and mapArgs methods to functions that produce a Matcher.

  6. implicit def convertToComposifier[T](f: (T) ⇒ Matcher[T]): Composifier[T]

    Implicit conversion that converts a function of T => Matcher[T] to an object that has composeTwice, mapResult and mapArgs methods.

    Implicit conversion that converts a function of T => Matcher[T] to an object that has composeTwice, mapResult and mapArgs 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 a Matcher[T]

    returns

    an object that has composeTwice, mapResult and mapArgs methods.
