Overview

Provides a way to filter the registry according to the suffix on loaded paths.

A test has an identity, e.g. the file and line number on which it’s defined.

A filter takes an identity, decomposes it into a file and suffix, loads the file, and registers the filter suffix.

When the filter is used to enumerate the registry, it will only return the tests that match the suffix.
