+testing:
+  test_patterns:
+    - Note that private and protected members are accessible in utests, as there is a macro to convert them to public
+    - Use descriptive test names that clearly indicate what functionality is being tested
+    - Group related tests together (e.g., all tests for one class should be consecutive)
+    - Test both success and failure paths, especially for error handling scenarios
+    - Verify edge cases like sequence number wrap-around, cache overflow, and null inputs
+    - Use existing mock helper functions for consistency and maintainability
 
+  error_handling_macros:
+    - Use HELPER_EXPECT_SUCCESS(x) when expecting a function to succeed (returns srs_success)
+    - Use HELPER_EXPECT_FAILED(x) when expecting a function to fail (returns non-srs_success error)
+    - These macros automatically handle error cleanup and provide better error messages
+    - Always declare "srs_error_t err;" at the beginning of test functions that use these macros

+      Example:
+      VOID TEST(MyTest, TestFunction) {
+          srs_error_t err;
+          HELPER_EXPECT_SUCCESS(some_function_that_should_succeed());
+          HELPER_EXPECT_FAILED(some_function_that_should_fail());
+      }
