This class supports the syntax of FlatSpec, WordSpec, FixtureFlatSpec,
and FixtureWordSpec.
Implicitly converts an object of type String to a StringShouldWrapperForVerb,
to enable should methods to be invokable on that object.
Implicitly converts an object of type String to a StringShouldWrapperForVerb,
to enable should methods to be invokable on that object.
Provides an implicit conversion that adds
shouldmethods toStringto support the syntax ofFlatSpec,WordSpec,FixtureFlatSpec, andFixtureWordSpec.For example, this trait enables syntax such as the following test registration in
FlatSpecandFixtureFlatSpec:"A Stack (when empty)" should "be empty" in { ... } ^It also enables syntax such as the following shared test registration in
FlatSpecandFixtureFlatSpec:"A Stack (with one item)" should behave like nonEmptyStack(stackWithOneItem, lastValuePushed) ^In addition, it supports the registration of subject descriptions in
WordSpecandFixtureWordSpec, such as:"A Stack (when empty)" should { ... ^And finally, it also supportds the registration of subject descriptions with after words in
WordSpecandFixtureWordSpec. For example:def provide = afterWord("provide") "The ScalaTest Matchers DSL" should provide { ^The reason this implicit conversion is provided in a separate trait, instead of being provided directly in
FlatSpec,WordSpec,FixtureFlatSpec, andFixtureWordSpec, is because an implicit conversion provided directly would conflict with the implicit conversion that providesshouldmethods onStringin theShouldMatcherstrait. By contrast, there is no conflict with the separateShouldVerbtrait approach, because:FlatSpec,WordSpec,FixtureFlatSpec, andFixtureWordSpecmix inShouldVerbdirectly, andShouldMatchersextendsShouldVerb, overriding theconvertToStringShouldWrapperimplicit conversion function.So whether or not a
FlatSpec,WordSpec,FixtureFlatSpec, orFixtureWordSpecmixes inShouldMatchers, there will only be one implicit conversion in scope that addsshouldmethods toStrings.Also, because the class of the result of the overriding
convertToStringShouldWrapperimplicit conversion method provided inShouldMatchersextends this trait'sStringShouldWrapperForVerbclass, the four uses ofshouldprovided here are still available. These fourshouldare in fact available to any class that mixes inShouldMatchers, but each takes an implicit parameter that is provided only inFlatSpecandFixtureFlatSpec, orWordSpecandFixtureWordSpec.
