Maxim Mironjuk - August 11, 2025

Maxim Mironjuk - August 11, 2025

Understanding Path Mappings in PhpStorm Instead of Trial and Error

Maxim Mironjuk - August 08, 2025

Securing Plugin Order and sortOrder with Tests

Maxim Mironjuk - August 08, 2025

Multiple plugins on the same method silently depend on the sortOrder in di.xml. A test that documents the actual execution order prevents a new plugin from silently tipping over an existing order and, with it, the behavior.
