Contributions summary:David primarily focused on refactoring and improving testing within the Axon Framework. Their contributions involved replacing deprecated methods (`whenThenTimeElapses`, `whenThenTimeAdvancesTo`) with new ones (`whenTimeElapses`, `whenTimeAdvancesTo`) across several test classes. They also updated the `TestExecutor` interface and the `AggregateTestFixture` to accommodate these changes and ensure backward compatibility. These changes involved both code modifications and adjustments to testing assertions to maintain the framework's functionality.
