I have setup integration tests for app/code that was working fine.

Now I have a module that adds some product attributes in a setup script, it doesn't have any tests but it is part of the project. When running integration tests it will fail with the exception: Wrong entity ID

This happens when the setup does this:
$eavSetup->addAttribute(Product::ENTITY, $attributeCode, $attributeDefinition);

The error happens because table eav_entity_type is empty for some reason. what am I missing something here?
