IETS002: tests_init

The test directory and its sub-directories contain init.py.

Category: tests · Applies to: eval, helper

What it does

Checks <tests-root>/<name>/ and every directory beneath it for an __init__.py, ignoring cache directories. One diagnostic per directory. Skipped when the tests live directly under the tests root, where there is nothing to collide with, and for a helper package with no tests/<name>/ directory.

Why is this bad?

Per-evaluation test trees with duplicate module basenames (test_scorer.py in two evaluations) collide during pytest collection unless each tree is a package.

Suppress on a line with # inspect-evals-lint: ignore[IETS002] or ignore[tests_init]; select or ignore it in configuration by either, or by the prefix IETS.
