Test Coverage Analyzer provides deep visibility into how well your test suites exercise agent-generated code. By using deterministic Abstract Syntax Tree (AST) traversal, it identifies exactly which functions and classes are covered and which remain untested. Use analyze_code_coverage to get a full coverage percentage and a list of uncovered nodes. Use identify_uncovered_complex_logic to pinpoint high-risk areas where complex logic lacks verification. You can also use map_test_targets to confirm which specific code elements are being exercised by your tests. This tool helps ensure the auditability and reliability of LLM-generated workflows.

3 tools expose this connector's capabilities to your AI agent.

analyze_code_coverage

Provides a complete overview of how well the provided test suite exercises the source code

map_test_targets

Determines exactly which functions and classes are being targeted by the provided test suite

identify_uncovered_complex_logic

Specifically pinpoints high-risk areas where complex logic is completely unverified

What is the test coverage for this code?

The current test coverage is 85%. There are 2 uncovered nodes at lines 12 and 45.

Are there any high-risk areas in my code?

Yes, the function `process_data_stream` at line 50 is high risk due to its high complexity and zero test coverage.

Which functions are being tested by this suite?

The test suite targets the following: `calculate_total` (covered) and `validate_user` (uncovered).

Coverage is calculated by comparing the set of all executable nodes in the source AST against the set of nodes traversed during the test execution simulation.
