interpolate_name

interpolate_name consists in a set of procedural macro attributes geared towards reduce the boilerplate while writing repetitive tests.

• interpolate_test: a quick way to test the same function by passing specific arguments and have a test entry for each of them.
• interpolate_name: a simple function renamer that can be combined with macros to support more complex patterns.

Procedural macro attribute to do not repeat yourself while testing
