testingreach-coverage

- Increase unit test coverage to approach 100 percent for a given function. - Context and constraints: - You will be given a specific function to work on. - All tests and code must strictly follow: - @.claude/skills/testing.format_rules/SKILL.md for tests - @.claude/skills/coding.format_rules/SKILL.md for any code - Focus on meaningful behavior and correctness rather than superficial coverage. - If any part of the task is unclear or underspecified, stop and ask for clarification before proceeding. ## Step 1: Establish Current Coverage - Identify the test file corresponding to the target function Example: helpers/hllm_cli.py → helpers/test/test_hllm_cli.py - Run the following command and record the results: ``` pytest --cov=yourpkg --cov-report=term-missing --cov-report=html ``` - Summarize which lines and branches are not covered. ## Step 2: Design a Testing Plan - Analyze uncovered code paths and behaviors. - Propose a clear testing plan that: - Tests functions modularly before testing interactions. - Prioritizes end-to-end and user-visible behavior over incidental implementation details. - Avoids testing assertions, defensive checks, or invalid inputs unless they are critical to correctness. - Explicitly map each uncovered area to one or more proposed tests. ## Step 3: Specify Tests Without Implementation - Define test classes and test method names. - For each proposed test: - Describe the input data. - Describe the expected output or observable behavior. - Do not write executable test code at this stage. ## Step 4: Implement After Approval - Wait for user confirmation or feedback on the testing plan. - After approval: - Implement the tests according to the approved plan. - Re-run coverage and verify that coverage for the target function is near 100 percent. - Report final coverage results and remaining gaps, if any. Important rules: - Do not implement tests before the plan is approved. - Do not proceed if instructions or requirements are ambiguous. - Always adhere to the formatting and style guides referenced above.
