Instances of this class are returned via the decided by <an Equality>
syntax, and enables afterBeing to be invoked on it. Here's an example, given an
Equality[String] named myStringEquality:
result should equal ("hello") (decided by myStringEquality afterBeing lowerCased)

Provides ScalaTest's “explicitly DSL,” which facilitates the explicit specification of an
Equality[T]or aUniformity[T]whereEquality[T]is taken implicitly.The Explicitly DSL can be used with the
===and!==operators of Scalactic as well as theshouldequal,be,contain, and===syntax of ScalaTest matchers.If you want to customize equality for a type in general, you would likely want to place an implicit
The explicitly DSL also provides support for specifying a one-off equality that is based on a normalization. For example, Scalactic offers aEquality[T]for that type in scope (or inT's companion object). That implicit equality definition will then be picked up and used when that type is compared for equality with theequal,be, andcontainmatchers in ScalaTest tests and with===in both tests and production code. If you just want to use a custom equality for a single comparison, however, you may prefer to pass it explicitly. For example, if you have an implicitEquality[String]in scope, you can force a comparison to use the default equality with this syntax:StringNormalizationstrait that provides methods such astrimmedandlowerCasedthat returnNormalization[String]instances that normalize by trimming and lower-casing, respectively. If you bring those into scope by mixing in or importing the members ofStringNormalizations, you could use the explicitly DSL like this: If you prefer not to use English-like DSLs in your production code, you can alternatively not use theExplicitlytrait and instead write:
