Step 4: Coverage Plan & Execution Strategy
STEP GOAL
Create the test coverage matrix, prioritize scenarios, and define execution strategy, resource estimates, and quality gates.
MANDATORY EXECUTION RULES
- 📖 Read the entire step file before acting
- ✅ Speak in
{communication_language}
- 🚫 Avoid redundant coverage across test levels
EXECUTION PROTOCOLS:
- 🎯 Follow the MANDATORY SEQUENCE exactly
- 💾 Record outputs before proceeding
- 📖 Load the next step only when instructed
CONTEXT BOUNDARIES:
- Available context: config, loaded artifacts, and knowledge fragments
- Focus: this step’s goal only
- Limits: do not execute future steps
- Dependencies: prior steps’ outputs (if any)
MANDATORY SEQUENCE
CRITICAL: Follow this sequence exactly. Do not skip, reorder, or improvise.
1. Coverage Matrix
For each requirement or risk-driven scenario:
- Decompose into atomic test scenarios
- Select test level (E2E / API / Component / Unit) using
test-levels-framework.md
- Ensure no duplicate coverage across levels
- Assign priorities (P0–P3) using
test-priorities-matrix.md
- Map NFR-derived risks to planned validation scenarios and evidence sources
Priority rules:
- P0: Blocks core functionality + high risk + no workaround
- P1: Critical paths + medium/high risk
- P2: Secondary flows + low/medium risk
- P3: Nice-to-have, exploratory, benchmarks
2. NFR Coverage and Evidence Plan
For each in-scope NFR category:
- Map the NFR to one or more planned validation scenarios
- Select the right validation level/tool (for example: API/UI tests for auth and resilience, k6 for load/performance, CI/static analysis for maintainability, monitoring/logs for reliability)
- Identify the expected evidence artifact that
nfr-assess should consume later
- Mark missing thresholds or missing evidence sources as blockers, risks, or assumptions
Keep this concise. Do not include full NFR evidence assessment tables or final PASS/CONCERNS/FAIL decisions in test design.
3. Execution Strategy (Keep Simple)
Use a PR / Nightly / Weekly model:
- PR: All functional tests if <15 minutes
- Nightly/Weekly: Long-running or expensive suites (perf, chaos, large datasets)
- Avoid re-listing all tests (refer to coverage plan)
4. Resource Estimates (Ranges Only)
Provide intervals (no false precision):
- P0: e.g., “~25–40 hours”
- P1: e.g., “~20–35 hours”
- P2: e.g., “~10–30 hours”
- P3: e.g., “~2–5 hours”
- Total and timeline as ranges
5. Quality Gates
Define thresholds:
- P0 pass rate = 100%
- P1 pass rate ≥ 95%
- High-risk mitigations complete before release
- Coverage target ≥ 80% (adjust if justified)
- NFR validation evidence identified for each in-scope NFR category
- Full NFR PASS/CONCERNS/FAIL status deferred to
nfr-assess when evidence exists
6. Save Progress
Save this step’s accumulated work to {outputFile}.
- If
{outputFile} does not exist (first save), create it with YAML frontmatter:
---
workflowStatus: 'in-progress'
totalSteps: 5
stepsCompleted: ['step-04-coverage-plan']
lastStep: 'step-04-coverage-plan'
nextStep: '{nextStepFile}'
lastSaved: '{date}'
---
Then write this step’s output below the frontmatter.
- If
{outputFile} already exists, update:
- Set
workflowStatus: 'in-progress'
- Set
totalSteps: 5
- Add
'step-04-coverage-plan' to stepsCompleted array (only if not already present)
- Set
lastStep: 'step-04-coverage-plan'
- Set
nextStep: '{nextStepFile}'
- Set
lastSaved: '{date}'
- Append this step’s output to the appropriate section of the document.
Load next step: {nextStepFile}
🚨 SYSTEM SUCCESS/FAILURE METRICS:
✅ SUCCESS:
- Step completed in full with required outputs
❌ SYSTEM FAILURE:
- Skipped sequence steps or missing outputs
Master Rule: Skipping steps is FORBIDDEN.
