The RestFixture is a FitNesse (http://fitnesse.org) fixture that allows developers and/or product owners to write test fixtures for REST services with simplicity in mind. The idea is to write tests that are self documenting and easy to write and read, without the need to write Java code. The fixture allows test writers to express tests as actions (any of the allowed HTTP methods) to operate on resource URIs and express expectations on the content of the return code, headers and body. All without writing one single line of Java code. And it also works as a living/executable documentation of the API.

There is a newer version: 4.4

{@code header}	applies the expression to the response headers
{@code body}	applies the expression to the body
{@code body:xml}	applies the expression to the body as XML. expressions are XPaths.
{@code js}	applies expression to body as JSON
{@code const}	it's actually a shortcut to allow setting of const labels
