Issue & Reproduction Steps

This PR adds a test to ensure that cache invalidation works correctly for routes using the etag middleware with the etag_tables configuration. The existing functionality correctly handled ETag generation and cache invalidation, but there was no explicit test coverage for the scenarios where changes in updated_at in the specified tables should trigger cache invalidation.

1. Define a route using the etag middleware and specify etag_tables in the route’s defaults.
2. Perform an initial request to retrieve the ETag.
3. Update the updated_at column in the database for the specified table.
4. Expect the ETag to change and invalidation to occur.

Solution

• Introduced a new test case to verify cache invalidation when the updated_at field in the specified tables changes.
• Ensured the test validates that the ETag changes after database updates and remains the same if no updates are made.

How to Test

1. Setup:

• Create a route using the etag middleware with etag_tables pointing to a database table (e.g., processes).

2. Run the test:

• Execute a manual test to ensure the ETag updates correctly when updated_at in the database changes.
• Validate that:
  • The ETag remains unchanged if there are no updates.
  • The ETag changes after an update to updated_at.
  • A 200 OK is returned when the client sends an outdated ETag.

The functionality now has complete test coverage to ensure the proper behavior of cache invalidation using etag_tables.
