See creating your custom operators documentation section.

Some people would argue that grappa is more verbose. It certainly is, but comes with several benefits that you won’t have without it, such as:

Expressivity: code intentions are more clear, easy to read and understand.
Readability: besides trivial assertions, it help you writing complex assertions is a human-friendly way.
Underline complex assertions with an expressive, human-friendly DSL.
Great error report system with detailed failure reasons, subject/expectation comparison diff, embedded code.
Lazy evaluation allows grappa understand what you’re expressing in code to perform more fine-grane validations.
grappa does type validation under the hood to ensure your providing a valid type.
grappa is an extensible assertion layer that can be used in a lot of ways, such as for HTTP protocol testing.
