Swarm Agent Implementation

Each agent in the swarm is focused on its module:

class ModuleTestAgent:
    def __init__(self, module_path: str, llm):
        self.module_path = module_path
        self.llm = llm

    async def analyze_and_generate(self, codebase_path: str) -> RawTestSuite:
        # Step 1: Read the module source files
        source_files = self.read_module_files(
            os.path.join(codebase_path, self.module_path)
        )

        # Step 2: Identify testable functions/classes
        analysis = self.llm.generate(f"""
        Analyze these source files and identify all testable functions:
        {source_files}

        For each function, list:
        - Function name and signature
        - What it does (one sentence)
        - Input constraints (from type hints, validation, decorators)
        - Error paths (exceptions raised, error returns)
        - Dependencies (other functions called, external services)
        """)

        # Step 3: Generate tests for each function
        tests = self.llm.generate(f"""
        Based on this analysis:
        {analysis}

        Generate a test file with:
        - At least 2 tests per function (happy path + error case)
        - Boundary value tests for constrained inputs
        - Parametrized tests for enum/boolean parameters
        - Proper fixtures for database/HTTP mocking

        return RawTestSuite(
            module=self.module_path,
            tests=tests,
            agent_id=self.agent_id,
            analysis=analysis
        )
