Increased pytest reporting detail
Increased pytest reporting detail

This is increasing the amount of details reported by pytest on failures.
This is useful when functions are used to assert on state, e.g.
must_contain_entry, which could have the values partially hidden by the
assertion instrospection.

The flag `--show-locals` adds to the end of each frame the list of local
variables and their values.

The flag `--tb=long` shows the source code of each frame with
annotations.
