Running tests on Codeception. Upgraded 2.4.0 to 2.4.1 and 40 out of 280 tests fail. Apparently Yii2 module has been "refactored". Fine, upgrade to 2.4.2 that fixes the issues reported in 2.4.1 - another set of tests fail for different reasons. Digging deeper. Turns out the "refactoring" includes a very opinionated change of behaviour when components have some internal state. But if it's acceptable to pass testing framework module rewrite in a minor bugfix release - then fuck Codeception in general.
