trait
ShouldVerb
extends
AnyRefshould
methods to String
to support the syntax of FlatSpec
, WordSpec
, FixtureFlatSpec
,
and FixtureWordSpec
.
For example, this trait enables syntax such as the following test registration in FlatSpec
and FixtureFlatSpec
:
"A Stack (when empty)" should "be empty" in { ... } ^
It also enables syntax such as the following shared test registration in FlatSpec
and FixtureFlatSpec
:
"A Stack (with one item)" should behave like nonEmptyStack(stackWithOneItem, lastValuePushed) ^
In addition, it supports the registration of subject descriptions in WordSpec
and FixtureWordSpec
, such as:
"A Stack (when empty)" should { ... ^
And finally, it also supportds the registration of subject descriptions with after words
in WordSpec
and FixtureWordSpec
. 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
, and
FixtureWordSpec
, is because an implicit conversion provided directly would conflict
with the implicit conversion that provides should
methods on String
in the ShouldMatchers
trait. By contrast, there is no conflict with
the separate ShouldVerb
trait approach, because:
FlatSpec
, WordSpec
, FixtureFlatSpec
, and FixtureWordSpec
mix in ShouldVerb
directly, andShouldMatchers
extends ShouldVerb
, overriding the
convertToStringShouldWrapper
implicit conversion function.
So whether or not
a FlatSpec
, WordSpec
, FixtureFlatSpec
, or FixtureWordSpec
mixes in ShouldMatchers
, there will only be one
implicit conversion in scope that adds should
methods to String
s.
convertToStringShouldWrapper
implicit conversion method provided in ShouldMatchers
extends this trait's
StringShouldWrapperForVerb
class, the four uses of should
provided here
are still available. These four should
are in fact available to any class
that mixes in ShouldMatchers
, but each takes an implicit parameter that is provided
only in FlatSpec
and FixtureFlatSpec
, or WordSpec
and
FixtureWordSpec
.
