I updated all my dependencies, and now the constructors are marked final.

So, I set up a static class property in setUpBeforeClass instead, but when I try to run the test, I get

Error: Typed static property Test::$property must not be accessed before initialization

I have a workaround by calling self::setUpBeforeClass(); at the top of the data providers, and ensuring the logic in setUpBeforeClass handles being run multiple times.
