This class supports the syntax of FlatSpec
, WordSpec
, org.scalatest.fixture.FlatSpec
,
and org.scalatest.fixture.WordSpec
.
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
should
methods toString
to support the syntax ofFlatSpec
,WordSpec
,org.scalatest.fixture.FlatSpec
, andorg.scalatest.fixture.WordSpec
.For example, this trait enables syntax such as the following test registration in
FlatSpec
andorg.scalatest.fixture.FlatSpec
:It also enables syntax such as the following shared test registration in
FlatSpec
andorg.scalatest.fixture.FlatSpec
:"A Stack (with one item)" should behave like nonEmptyStack(stackWithOneItem, lastValuePushed) ^
In addition, it supports the registration of subject descriptions in
WordSpec
andorg.scalatest.fixture.WordSpec
, such as:"A Stack (when empty)" should { ... ^
And finally, it also supportds the registration of subject descriptions with after words in
WordSpec
andorg.scalatest.fixture.WordSpec
. For example:The reason this implicit conversion is provided in a separate trait, instead of being provided directly in
FlatSpec
,WordSpec
,org.scalatest.fixture.FlatSpec
, andorg.scalatest.fixture.WordSpec
, is because an implicit conversion provided directly would conflict with the implicit conversion that providesshould
methods onString
in theShouldMatchers
trait. By contrast, there is no conflict with the separateShouldVerb
trait approach, because:FlatSpec
,WordSpec
,org.scalatest.fixture.FlatSpec
, andorg.scalatest.fixture.WordSpec
mix inShouldVerb
directly, andShouldMatchers
extendsShouldVerb
, overriding theconvertToStringShouldWrapper
implicit conversion function.So whether or not a
FlatSpec
,WordSpec
,org.scalatest.fixture.FlatSpec
, ororg.scalatest.fixture.WordSpec
mixes inShouldMatchers
, there will only be one implicit conversion in scope that addsshould
methods toString
s.Also, because the class of the result of the overriding
convertToStringShouldWrapper
implicit conversion method provided inShouldMatchers
extends this trait'sStringShouldWrapperForVerb
class, the four uses ofshould
provided here are still available. These fourshould
are in fact available to any class that mixes inShouldMatchers
, but each takes an implicit parameter that is provided only inFlatSpec
andorg.scalatest.fixture.FlatSpec
, orWordSpec
andorg.scalatest.fixture.WordSpec
.
