Cache tests

[fogelito]

Summary by CodeRabbit

• Tests

  • Added comprehensive test coverage for the cache system to validate resource management, status tracking, and lifecycle operations including add, overwrite, status transitions, key resolution, and aggregation across resource types.

• Chores

  • Added a developer note inside migration cache logic; no functional or runtime behavior changes.

Walkthrough

A comment block is added inside the update method of src/Migration/Cache.php suggesting a direct call to $this->add($resource); no runtime behavior or control flow is changed. A new PHPUnit test file tests/Migration/Unit/General/CacheTest.php is added, containing a CacheTest::testTestCache() method that exercises Cache operations: adding and overwriting Database, Table, and Row resources, updating statuses, resolving cache keys, and asserting per-resource and per-status aggregations.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Inspect the inline comment in src/Migration/Cache.php for accuracy and clarity relative to current implementation.
• Review the new test tests/Migration/Unit/General/CacheTest.php for correct assertions and that it validates real behavior (not tautological checks).
• Verify namespace, class/method naming, and PHPUnit usage/annotations conform to project conventions.

🧹 Nitpick comments (4)

src/Migration/Cache.php (1)

134-136: Consider verifying the TODO suggestion before implementing.

The TODO suggests replacing the current logic with a direct call to $this->add($resource). While this would simplify the method, verify that it preserves the current behavior for all resource types, particularly for non-ROW/DOCUMENT resources where the method currently performs an existence check before setting the cache entry.

Would you like me to generate a script to verify all usages of the update() method to ensure the suggested refactoring wouldn't break existing behavior?

tests/Migration/Unit/General/CacheTest.php (3)

98-99: Clarify the test intent.

The call to resolveResourceCacheKey($row) doesn't remove anything from the cache—it only computes and returns the key. The assertion correctly verifies that rows use status counters rather than individual keys, but placing it immediately after resolveResourceCacheKey may confuse readers into thinking the method has side effects on the cache structure.

Consider moving this assertion earlier (e.g., right after line 96) to make the test flow clearer.

---

14-108: Consider splitting into focused test methods.

This single test method covers multiple scenarios: database add/update, table add, row status counters, and overwrite behavior. Splitting it into separate methods (e.g., testAddAndUpdateDatabase, testAddTable, testRowStatusCounters, testOverwriteBehavior) would improve maintainability and make test failures easier to diagnose.

Additionally, the method name testTestCache is redundant. Consider a more descriptive name like testCacheLifecycle if keeping it as one method.

---

21-21: Prefer conventional static method call syntax.

Using $db1::getName() to call a static method is valid but unconventional. For better clarity, use Database::getName() when calling static methods, or use $db1->getName() if it were an instance method.

This pattern appears throughout the test (lines 21, 30, 66, 86).

Learning: In the utopia-php/migration codebase, the Utopia Database package does not have a Memory adapter. When testing classes that require a Database instance (like CSV), use PHPUnit's createMock() method to create proper mocks instead of trying to instantiate real database adapters.
