Hi team,
This PR adds a comprehensive, table-driven unit test suite for the
`Validate()` and `GetType()` methods of all types that implement the
`table.Requirement` interface.
#### Motivation
The `Requirement` validation logic is a critical part of the commit
protocol, ensuring transactional safety for table updates. However, this logic
was not explicitly covered by unit tests, leaving it potentially vulnerable to
future regressions.
This test suite is intended to serve as a **gatekeeper** for this important
feature. It ensures that the contract of each requirement's `Validate` method
is well-defined and that any future, unintended changes to this core logic will
be caught by the CI.
#### Implementation Details
- A new test suite, `TestRequirementValidation`, has been added to
`table/requirement_test.go`.
- It uses a lightweight, mock `table.Metadata` object to precisely control
the conditions for each test case without needing to construct a full metadata
object.
- The tests cover all key scenarios for each requirement type, including:
- Success on a valid state.
- Failure on an invalid state (e.g., mismatched UUIDs, conflicting
snapshot IDs).
- Correct behavior when validating against a non-existent (`nil`)
table, which is crucial for the `assert-create` requirement.
Happy to make any adjustments or answer any questions. Thanks!
