Hook method for deconstructing the test fixture after testing it.

test_build_level_only()

Inside build_level, packages are found, downloaded and installed only in the chosen level.

test_import_computes_no_level()

Importing the experiment model doesn’t look for a writable storage level.

test_missing_system_prefix()

A system prefix that doesn’t exist is an empty level that nothing writes to or creates.
