**issue (code-quality):** Don't import test modules. ([`dont-import-test-modules`](https://docs.sourcery.ai/Reference/Rules-and-In-Line-Suggestions/Python/Default-Rules/dont-import-test-modules))

<details><summary>Explanation</summary>Don't import test modules.

Tests should be self-contained and don't depend on each other.

If a helper function is used by multiple tests,
define it in a helper module,
instead of importing one test from the other.
