+ * Tests that SFSDKEncryptedURLCache properly stores and retrieves cached responses from actual network requests.
+ * 
+ * This test verifies that:
+ * 1. Network requests made via makeRequestsWithBaseURL populate the encrypted cache
+ * 2. Subsequent identical requests retrieve responses from the cache instead of the network
+ * 3. The test cache subclass correctly tracks both storage and retrieval operations
+ * 4. The encrypted cache works end-to-end with real network responses
+ * 
+ * Test Flow:
+ * - Phase 1: Call makeRequestsWithBaseURL and verify cache storage occurs
+ * - Phase 2: Call makeRequestsWithBaseURL again and verify cache retrieval occurs
+ * 
+ * Implementation Details:
+ * - Uses a TestSFSDKEncryptedURLCache subclass to monitor cache operations
+ * - Makes actual network requests to Salesforce mobile SDK test resources
+ * - Uses our direct cache testing approach rather than relying on NSURLSession behavior
+ * 
+ * Note: This approach bypasses the NSURLSession session-level cache partitioning issue
+ * by using our custom test cache that tracks operations directly.
