Test Suggestions

This skill suggests which tests to run based on code changes.

When to Use

• User modifies source files
• User asks "what tests should I run?"
• User asks "will my changes break anything?"
• Before pushing changes

How It Works

1. Identify changed files from git status
2. Query test impact graph for file → test mapping
3. Consider historical co-failures
4. Prioritize by impact score
5. Suggest minimal test set

Implementation

Use the argus_what_to_test MCP tool:

• Input: { "diff": "<git diff>", "project_id": "<project>" }
• Returns: Prioritized list of tests with reasoning and estimated run time

Output Format

Suggested Tests

Priority	Test	Reason
🔴 Must Run	test_auth_login	Directly affected by auth.py changes
🟡 Should Run	test_api_users	Uses UserService (transitive)
🟢 Optional	test_e2e_checkout	Low probability of impact

Quick Command

pytest tests/test_auth_login.py tests/test_api_users.py

Estimated time: ~2 minutes
