Use of context() is no longer recommend. Instead omit it, and messages
will use the name of the file instead. This ensures that the context and
test file name are always in sync.
Usage
context(desc)
Arguments
desc
description of context. Should start with a capital letter.
Details
A context defines a set of tests that test related functionality. Usually
you will have one context per file, but you may have multiple contexts
in a single file if you so choose.
