Automated Test Planner

Creates Story test task with comprehensive automated test coverage (E2E/Integration/Unit) based on Risk-Based Testing methodology and REAL manual testing results.

Inputs

Resolution: Story Resolution Chain. Status filter: To Review

Purpose & Scope

• Create comprehensive test task for Story automation
• Calculate risk-based priorities (Impact x Probability)
• Generate 11-section test plan from manual test results
• Delegate to ln-301-task-creator (CREATE) or ln-302-task-replanner (REPLAN)
• NOT for: manual testing (ln-522), research (ln-521), orchestration (ln-520)

When to Use This Skill

This skill should be used when:

• Invoked by ln-520-test-planner after ln-521 research and ln-522 manual testing
• All implementation tasks in Story are Done
• Manual testing results documented in Linear comment (from ln-522)
• Research findings available in Linear comment (from ln-521)

Prerequisites:

• All implementation Tasks in Story status = Done
• ln-521-test-researcher completed (research comment exists)
• ln-522-manual-tester completed (manual test results in Linear comment)

Automation: Supports autoApprove: true (default when invoked by ln-520) to skip manual confirmation.

When NOT to Use

Do NOT use if:

• Manual testing NOT completed -> Wait for ln-522
• Research NOT completed -> Wait for ln-521
• Implementation tasks NOT all Done -> Complete impl tasks first

Workflow

Phase 0: Tools Config

MANDATORY READ: Load shared/references/tools_config_guide.md, shared/references/storage_mode_detection.md, and shared/references/input_resolution_pattern.md

Extract: task_provider = Task Management → Provider (linear | file).

Phase 1: Discovery (Automated)

1. Resolve storyId: Run Story Resolution Chain per guide (status filter: [To Review]).
2. Auto-discover Team ID from docs/tasks/kanban_board.md (see CLAUDE.md "Configuration Auto-Discovery")

Phase 2: Story + Tasks Analysis (NO Dialog)

Step 0: Study Project Test Files

1. Scan for test-related files:
   • tests/README.md (commands, setup, environment)
   • Test configs (jest.config.js, vitest.config.ts, pytest.ini)
   • Existing test structure (tests/, tests/ directories)
   • Coverage config (.coveragerc, coverage.json)
2. Extract: test commands, framework, patterns, coverage thresholds
3. Ensures test planning aligns with project practices

Step 1: Load Research and Manual Test Results

1. Fetch Story (must have label "user-story"):
   • IF task_provider = linear: get_issue(storyId) — extract Story.id (UUID, NOT short ID)
   • IF task_provider = file: Read story.md — extract Story metadata
2. Load research comment (from ln-521): "## Test Research: {Feature}"
   • IF task_provider = linear: list_comments(issueId=storyId) → find matching comment
   • IF task_provider = file: Glob("docs/tasks/epics/*/stories/*/comments/*.md") → find matching comment
3. Load manual test results comment (from ln-522): "## Manual Testing Results"
   • Same approach as research comment above
   • If not found -> ERROR: Run ln-520-test-planner pipeline first
4. Parse sections: AC results (PASS/FAIL), Edge Cases, Error Handling, Integration flows
5. Map to test design: PASSED AC -> E2E, Edge cases -> Unit, Errors -> Error handling, Flows -> Integration

Step 2: Analyze Story + Tasks

1. Parse Story: Goal, Test Strategy, Technical Notes
2. Fetch all child Tasks (status = Done):
   • IF task_provider = linear: list_issues(parentId=Story.id, state="Done")
   • IF task_provider = file: Glob("docs/tasks/epics/*/stories/*/tasks/*.md") → filter by **Status:** Done
3. Analyze each Task:
   • Components implemented
   • Business logic added
   • Integration points created
   • Conditional branches (if/else/switch)
4. Identify what needs testing

Phase 3: Parsing Strategy for Manual Test Results

Process: Locate Linear comment with "Manual Testing Results" header -> Verify Format Version 1.0 -> Extract structured sections (Acceptance Criteria, Test Results by AC, Edge Cases, Error Handling, Integration Testing) using regex -> Validate (at least 1 PASSED AC, AC count matches Story, completeness check) -> Map parsed data to test design structure

Error Handling: Missing comment -> ERROR (run ln-522 first), Missing format version -> WARNING (try legacy parsing), Required section missing -> ERROR (re-run ln-522), No PASSED AC -> ERROR (fix implementation)

Phase 4: Risk-Based Test Planning (Automated)

MANDATORY READ: Load shared/references/risk_based_testing_guide.md for complete methodology.

E2E-First Approach: Prioritize by business risk (Priority = Impact x Probability), not coverage metrics.

Workflow:

Step 1: Risk Assessment

Calculate Priority for each scenario from manual testing:

Priority = Business Impact (1-5) x Probability (1-5)

Decision Criteria:

• Priority ≥15 -> MUST test
• Priority 9-14 -> SHOULD test if not covered
• Priority <=8 -> SKIP (manual testing sufficient)

Step 2: E2E Test Selection (2-5): Baseline 2 (positive + negative) ALWAYS + 0-3 additional (Priority ≥15 only)

Step 3: Unit Test Selection (0-15): DEFAULT 0. Add ONLY for complex business logic (Priority ≥15): financial, security, algorithms

Step 4: Integration Test Selection: DEFAULT 0. Add ONLY if E2E gaps AND Priority ≥15: rollback, concurrency, external API errors

Step 5: Validation: Each test passes Usefulness Criteria (Priority ≥15, Confidence ROI, Behavioral, Predictive, Specific, Non-Duplicative)

Phase 5: Test Task Generation (Automated)

Generates complete test task per test_task_template.md (11 sections):

Sections 1-7: Context, Risk Matrix, E2E/Integration/Unit Tests (with Priority scores + justifications), Coverage, DoD

Section 8: Existing Tests to Fix (analysis of affected tests from implementation tasks)

Section 9: Infrastructure Changes (packages, Docker, configs - based on test dependencies)

Section 10: Documentation Updates (README, CHANGELOG, tests/README, config docs)

Section 11: Legacy Code Cleanup (deprecated patterns, backward compat, dead code)

Shows preview for review.

Phase 6: Confirmation & Delegation

Step 1: Preview generated test plan (always displayed for transparency)

Step 2: Confirmation logic:

• autoApprove: true (default from ln-520) -> proceed automatically
• Manual run -> prompt user to type "confirm"

Step 3: Check for existing test task

• IF task_provider = linear: list_issues(parentId=Story.id, label="tests")
• IF task_provider = file: Glob("docs/tasks/epics/*/stories/*/tasks/*.md") → filter by **Labels:** containing tests

Decision:

• Count = 0 -> CREATE MODE (Step 4a)
• Count >= 1 -> REPLAN MODE (Step 4b)

Step 4a: CREATE MODE (if Count = 0)

Invoke ln-301-task-creator worker with taskType: "test"

Pass to worker:

• taskType, teamId, storyData (Story.id, title, AC, Technical Notes, Context)
• researchFindings (from ln-521 comment)
• manualTestResults (from ln-522 comment)
• testPlan (e2eTests, integrationTests, unitTests, riskPriorityMatrix)
• infrastructureChanges, documentationUpdates, legacyCleanup

Worker returns: Task URL + summary

Step 4b: REPLAN MODE (if Count >= 1)

Invoke ln-302-task-replanner worker with taskType: "test"

Pass to worker:

• Same data as CREATE MODE + existingTaskIds

Worker returns: Operations summary + warnings

Step 5: Return summary to orchestrator (ln-520)

Definition of Done

Research and Manual Results Loaded:

• Research comment "## Test Research: {Feature}" found (from ln-521)
• Manual test results "## Manual Testing Results" found (from ln-522)
• At least 1 AC marked as PASSED

Risk-Based Test Plan Generated:

• Risk Priority Matrix calculated for all scenarios
• E2E tests: Baseline positive + negative, additional only if Priority ≥15
• Integration tests: ONLY if E2E doesn't cover AND Priority ≥15
• Unit tests: ONLY complex business logic with Priority ≥15
• Each test passes all 6 Usefulness Criteria
• No framework/library testing: Each test validates OUR business logic only

Test Task Description Complete (11 sections):

• All 11 sections populated per template
• Risk Priority Matrix included
• Each test beyond baseline 2 justified

Worker Delegation Executed:

• CREATE MODE: Delegated to ln-301-task-creator
• REPLAN MODE: Delegated to ln-302-task-replanner
• Linear Issue URL returned

Output:

• CREATE MODE: Linear Issue URL + confirmation
• REPLAN MODE: Operations summary + URLs

risk_based_testing_guide.md

Purpose: Risk-Based Testing methodology (detailed guide)

Location: shared/references/risk_based_testing_guide.md

test_task_template.md (CENTRALIZED)

Location: shared/templates/test_task_template.md

Usage: Workers (ln-301, ln-302) load via Template Loading logic

Critical Rules

• Manual results required: Never plan tests without ln-522 manual testing results — guessing coverage is worse than no tests
• E2E-first, not unit-first: Baseline is always 2 E2E (positive + negative); unit/integration added only for Priority >= 15
• No framework testing: Every test must validate OUR business logic; never test library/framework behavior
• Usefulness enforcement: Every test beyond baseline must pass all 6 Usefulness Criteria (see risk_based_testing_guide.md)
• Delegate, don't create: Task creation goes through ln-301/ln-302 workers; this skill generates the plan only

Best Practices

Minimum Viable Testing: Start with baseline E2E (positive + negative). Each additional test must pass all 6 Usefulness Criteria.

Risk-Based Testing: Prioritize by Business Impact x Probability. E2E-first from ACTUAL manual testing results. Priority ≥15 scenarios covered by tests.

Expected-Based Testing: For deterministic tests, compare actual vs expected using diff. MANDATORY READ: Load ../ln-522-manual-tester/SKILL.md — section "Test Design Principles".
