Bean overriding in tests refers to the ability to override specific beans in the

The bean overriding infrastructure searches for annotations on test classes as well as

`@BeanOverride` and instantiates the corresponding `BeanOverrideProcessor` which is
responsible for creating an appropriate `BeanOverrideHandler`.
The internal `BeanOverrideBeanFactoryPostProcessor` then uses bean override handlers to
alter the test's `ApplicationContext` by creating, replacing, or wrapping beans as
