🎯 What: The get_tool method in src/tools.py had a basic test test_get_tool in tests/test_tools.py, but lacked complete coverage for key boundary conditions and exact matching behavior given the nature of the parsed dictionary in memory (which can contain duplicate string names).
📊 Coverage: The test suite for get_tool is now expanded to ensure that edge cases are verified:

  • Checking that empty strings "" safely return None.
  • Checking that strings containing only whitespace " " return None.
  • Verification that when multiple tools are imported with the same name (e.g., "constants"), get_tool consistently respects first-match priority as implemented.
    Result: Test robustness and security are improved by ensuring that bounds and edge inputs to get_tool do not lead to exceptions or unpredictable states. This also fulfills the coverage request while maintaining deterministic test execution.

Code Review

This pull request expands the test coverage for the get_tool function by adding test cases for empty strings, whitespace, and duplicate tool names. A review comment suggests improving the robustness of the duplicate name test by explicitly asserting that duplicate entries exist in the test data, which prevents the test from silently skipping if the underlying data changes.

Pull request overview

Expands the Python unittest coverage for src.tools.get_tool to validate additional edge inputs and behavior when multiple mirrored tools share the same name in the snapshot.

Changes:

  • Add assertions that get_tool("") and get_tool(" ") return None.
  • Add a test for deterministic “first match wins” behavior for duplicate tool names (using "constants" in the snapshot).

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

The changes in this pull request are located in tests/test_tools.py. Specifically, you have added new test cases for get_tool between lines 54 and 66. These additions verify edge cases like empty strings, whitespace, and duplicate tool name handling to ensure the function behaves deterministically.

As I mentioned previously, the changes are located in tests/test_tools.py. You can see the new test cases added between lines 54 and 66 in the updated file. These tests specifically cover empty strings, whitespace inputs, and duplicate tool name handling to ensure the get_tool function behaves as expected.
