152-152: Consider making the size calculation more visible.The inline comment explaining the size calculation (10 total - 3 mammals - 3 birds = 4) is helpful. Consider making it even more maintainable by defining these numbers as constants or extracting them to a helper method.

7-8: LGTM! Good architectural enhancement.The addition of
JpaSpecificationExecutor<Animal>is a solid improvement that enables dynamic query capabilities and supports more comprehensive testing scenarios.This enhancement will facilitate:
- Dynamic query building for complex test scenarios
- Flexible search operations
- Better test coverage through specification-based queries

83-85: Consider index implications of case-insensitive searchThe implementation of case-insensitive search using
lower()is correct, but be aware that this might prevent the use of indexes on the field. For large tables, consider:
- Using a computed column with a lower-case index
- Creating a function-based index on LOWER(column)
110-113: Enhance error handling for new type conversionsWhile the new type conversions are good additions, consider providing more specific error messages for each type conversion failure. The current generic error message might not be sufficient for debugging issues with BigDecimal or UUID parsing.

53-153: Refactor tests using parameterized tests to reduce duplicationThe test methods for different query operators have similar structures with varying
SearchCriteriaand expected results. Consider refactoring these tests using parameterized tests to eliminate code duplication and enhance maintainability.

177-177: LGTM! Good practice for response structure validation.
The addition of jsonPath("$.content").isArray() assertion is a good practice. It ensures that the response structure remains consistent even when the result set is empty.

7-8: Verify test coverage for new specification capabilities.
Since this PR focuses on test enhancements, let's verify the test coverage for the new specification capabilities.
✅ Verification successful
Let me try a different search strategy to verify the test coverage.
Test coverage for specification capabilities is comprehensive
The codebase has thorough test coverage for the JpaSpecificationExecutor capabilities in EntitySpecificationTest.java, which includes tests for:
- All comparison operators (EQ, NE, LT, GT, LTE, GTE)
- Range operators (BETWEEN)
- Collection operators (IN, NOT_IN)
- String matching operators (LIKE, CONTAINS, STARTS_WITH, ENDS_WITH)
- Logical operators (OR, AND - though AND is currently disabled)
- Error handling for invalid field names
Each test verifies both the specification construction and the actual query results using the AnimalRepository.

11-11: LGTM! Required imports added for new type support
The new imports for BigDecimal, UUID, and DateTimeFormatter support the enhanced type conversion capabilities.
Also applies to: 14-14, 16-16
Line range hint 1-161: Verify test coverage for new type conversions
The changes look good overall, but please ensure there are comprehensive tests for:
- BigDecimal and UUID type conversions
- Case-insensitive LIKE/CONTAINS operations
- Single value predicate optimization
141-143: Verify Java version compatibility for List.getFirst()
The optimization for single value predicates is good, but List.getFirst() is a Java 21 feature. If the project needs to support older Java versions, consider using get(0) instead.
Also, the improved error message in the IllegalArgumentException is a good addition for debugging.
Also applies to: 147-148
✅ Verification successful
List.getFirst() is compatible with project's Java version
The project is configured to use Java 21 (<java.version>21</java.version>), which supports List.getFirst(). The usage is appropriate and doesn't require any changes.

🛠️ Refactor suggestion
Avoid using auto-generated IDs in test assertions
Relying on auto-generated IDs like "id" in test criteria can lead to flaky tests since IDs may differ across environments or runs. To ensure test reliability, use stable fields with known values, such as "name" or "type", in your SearchCriteria.

Correct the expected result in shouldBuildSpecificationForANDOperator
In the disabled test shouldBuildSpecificationForANDOperator, the assertion expects "Mammal" but the search criteria specify "Bird" with habitat "Forest". The assertion should expect "Bird" to match the criteria.
Apply this diff to correct the assertion:
- assertThat(results).isNotEmpty().extracting("type").containsOnly("Mammal");
+ assertThat(results).isNotEmpty().extracting("type").containsOnly("Bird");📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
