an Equality[T] instance that normalizes XML before testing for equality
Trait providing an implicit
Equality[T]for subtypes ofscala.xml.NodeSeqthat before testing for equality, will normalize left and right sides by removing empty XML text nodes and trimming non-empty text nodes.Here's an example of some unnormalized XML:
<summer> <day></day> <night> with lots of stars </night> </summer>Prior to testing it for equality, the implicit
Equality[T]provided by this trait would transform the above XML to:<summer><day></day><night>with lots of stars</night></summer>The goal of this trait is to provide an implicit
Equalityfor XML that makes it easier to write tests involving XML. White space is significant in XML, and is taken into account by the default equality for XML, accessed by invoking the==method on an XMLNodeSeq. Here's an example:The above assertion fails because of whitespace differences in the XML. When such whitespace differences are unimportant to the actual application, it can make it easier to write readable test code if you can compare XML for equality without taking into account empty text nodes, or leading and trailing whitespace in nonempty text nodes. This trait provides an
Equality[T]instance that does just that:
