For years, the test framework EcomDev_PHPUnit is quasi-standard for Magento unit tests. The current version is 0.3.7 and last state of official documentation is version 0.2.0 – since then, much has changed which you have to search yourself in code and GitHub issues. This series shall collect practical usage tips.
Tip #13: Speed up EAV fixtures
If you use the EAV fixtures to create products, categories and customers for tests, the fixture processor or EcomDev_PHPUnit makes a backup of the according tables before each test and restores it afterwards. Since the “magento_unit_tests” test database is copied from the current Magento database by default, this can result in much unnecessary overhead.
We can speed up tests that run several minutes many times over, by cleaning up the EAV tables in the test database. To do so, delete all rows in the entity main tables of the test DB, the associated attributes etc. are deleted automatically with triggers. With one exception: Do not delete the default root category:
delete from catalog_product_entity; delete from catalog_category_entity where entity_id > 2; delete from customer_entity;
