Could it be that fixtures are loaded too early? Need a minimal test case in codeception/yii2-tests. The hack of commenting out resetApplication() in _after() suggests that this code is called before the application is (re-)initialized.

Just wanted to make a note that it seems that it doesn't matter if you're trying to use MongoDB or MySQL/MariaDB. The problem triggers with both database systems.

I'm closing this due to its age. If it is still relevant in current versions feel free to create a new issue.

I still have this issue with:

"phpunit/phpunit": "^9.3",
"codeception/codeception": "^5.0",
"codeception/verify": "^2.2",
"codeception/module-asserts": "^3.0",
"codeception/module-yii2": "^1.1",
"codeception/module-phpbrowser": "^3.0",
"codeception/module-filesystem": "^3.0 || ^1.1"

The resetApplication comment hack works, but without it I get:

[yii\di\NotInstantiableException]
Failed to instantiate component or class "db".

Using the yii-starter-kit and trying to run tests with PHP 8 and Codeception 5. So far I can't find a definitive way to fix it.

Previously on PHP 7.4 and Codeception 2.4 and without codeception/module-yii2, run passed the tests.

free to create a new issue.
