Chapter 22: End-to-End Policy Testing
Testing complete methodology workflows across all stakeholder roles using Guardian's dry-run capabilities and VM0033 production patterns
Part V covered calculation writing and testing within individual blocks. Chapter 22 takes you beyond component testing to validate entire methodology workflows. Using Guardian's dry-run mode and VM0033's multi-stakeholder patterns, you'll learn to test complete project lifecycles from PDD submission through VCU token issuance.
Real-world methodology deployment demands testing workflows that span months of project activity, multiple stakeholder roles, and hundreds of documents. Guardian's dry-run system lets you simulate these workflows without blockchain costs or time delays.
Multi-Role Testing Framework
Virtual User Management in Dry-Run Mode
Guardian's dry-run mode creates a sandbox environment where you can simulate multiple users working simultaneously on different parts of your methodology. This approach mirrors production deployment while keeping testing fast and cost-effective.
Setting Up Dry-Run Testing Environment:
Import VM0033 Policy - Start with the VM0033 policy from shared artifacts
Enable Dry-Run Mode - Switch policy status from Draft to Dry-Run
Create Virtual Users - Set up users for each role (Project Proponent, VVB, OWNER)
Execute Complete Workflows - Test full project lifecycle with role transitions



Creating Virtual Users for Multi-Role Testing
Guardian allows Standard Registry users (OWNER role) to create virtual users for testing different stakeholder workflows. This feature enables testing approval chains and document handoffs. You can do so via API as well.
Testing User Progression Pattern:
Project Developer submits PDD using VM0033 project description schema
Standard Registry reviews and lists project on their platform
VVB accepts validation assignment from project proponent and conducts project review
VVB submits validation report with project assessment
Standard Registry approves or rejects project based on VVB validation
Project Developer submits monitoring reports over crediting period
VVB verifies monitoring data and submits verification reports
Standard Registry issues VCU tokens based on verified emission reductions
VM0033 Complete Workflow Testing
Let's walk through testing VM0033's complete workflow using the navigation structure from the policy JSON. This demonstrates how dry-run testing validates stakeholder interactions across the full methodology implementation.
Project Proponent Workflow Testing
Step 1: Project Creation and PDD Submission
The Project Proponent starts by accessing the "Projects" section and creating a new project using VM0033's PDD schema.

Testing should validate:
PDD form captures all required VM0033 parameters
Conditional schema sections display based on certification type (VCS vs VCS+CCB)
Calculation inputs integrate with custom logic blocks
Document submission creates proper audit trail

Step 2: VVB Selection and Assignment
After PDD submission and approval by registry, the project developer selects a VVB for validation. Testing confirms:
VVB selection interface displays approved VVB list
Assignment notification reaches selected VVB
Project status updates reflect VVB assignment
Document access permissions transfer correctly


VVB Workflow Testing
Step 3: Project Validation Process
VVBs access assigned projects through their dedicated interface. Validation testing includes:
Project document review and download capabilities
Validation checklist and assessment tools
Site visit data collection and documentation
Validation report submission using VM0033 validation schema



Step 4: Monitoring Report Verification
During the crediting period, VVBs verify monitoring reports:
Annual monitoring data review and validation
Field measurement verification against monitoring plan
Calculation accuracy assessment using VM0033 test artifacts
Verification report submission with emission reduction confirmation




Standard Registry (OWNER) Workflow Testing
Step 5: Project Pipeline Management
Standard Registry manages the complete project pipeline:
Project listing approval after successful validation
VVB accreditation and performance monitoring
Monitoring report review and compliance tracking
Token issuance authorization based on verified reductions
A verified presentation of tokens minted, each mint must have a trace of all the steps and data backing it.
Testing Workflow State Transitions
Guardian policies manage complex state transitions across multiple documents and stakeholders. Effective testing validates these transitions handle edge cases and error conditions properly.
Document Status Flow Testing:
PDD: Draft → Submitted → Under Review → Validated → Approved
Monitoring Report: Draft → Submitted → Under Verification → Verified → Credits Issued
VVB Status: Applicant → Under Review → Approved → Active → Suspended/Revoked
Potential Error Conditions:
VVB rejection scenarios and resubmission workflows
Incomplete document submission handling
Calculation errors and correction procedures
Role permission violations and access control
Concurrent user conflicts and resolution
Integration Testing with Production-Scale Data
Large Dataset Processing Validation
VM0033 projects can involve hundreds of hectares with complex stratification requiring extensive monitoring data. Testing with realistic data volumes validates performance and accuracy under production conditions.
Creating Test Datasets Based on VM0033 Allcot Case:
Using the VM0033_Allcot_Test_Case_Artifact.xlsx as foundation, create expanded datasets:
// Generate multiple project instances for load testing
function generateTestProjects(baseProject, count) {
const testProjects = [];
for (let i = 0; i < count; i++) {
const project = JSON.parse(JSON.stringify(baseProject));
project.project_details.G5 = `Test Project ${i + 1}`;
project.baseline_scenario.area_data.total_project_area = 100 + (i * 50);
testProjects.push(project);
}
return testProjects;
}
// Test concurrent project submissions
const multipleProjects = generateTestProjects(vm0033BaseProject, 25);
Multi-Year Monitoring Period Simulation
VM0033 projects can operate over 100-year crediting periods with annual monitoring in best scenarios. Testing long-term scenarios validates data consistency and calculation accuracy across extended timeframes using data patterns from our VM0033 test case artifact.
Testing should validate:
Calculation consistency across monitoring/crediting periods
Carbon stock accumulation tracking over decades
Emission reduction trend validation
Cross-Component Integration Validation
Schema-Workflow-Calculation Integration Testing
Part VI testing validates that components from Parts III-V work together seamlessly. This integration testing catches issues that component testing misses.
Schema Field Mapping Validation:
Using VM0033's schema structure, test field key consistency:
// Verify schema field keys match calculation block references
const pddSchema = vm0033Policy.schemas.find(s => s.name === "PDD Schema");
const calculationBlock = vm0033Policy.blocks.find(b => b.tag === "er_calculations");
// Test field key mapping
function validateFieldMapping(schema, calculationCode) {
const schemaFields = extractFieldKeys(schema);
const calculationReferences = extractFieldReferences(calculationCode);
const unmappedFields = calculationReferences.filter(
ref => !schemaFields.includes(ref)
);
if (unmappedFields.length > 0) {
console.error("Unmapped calculation references:", unmappedFields);
return false;
}
return true;
}
Important blocks for integration testing:
Test document flow through complete policy execution:
requestVcDocumentBlock captures schema data correctly
customLogicBlock processes schema fields without errors
sendToGuardianBlock stores calculated results properly
mintTokenBlock uses calculation outputs for token quantities
External Tool Integration
VM0033 integrates AR-Tool14 and AR-Tool05 for biomass and soil carbon calculations. Make sure you validate that these tools work correctly within complete policy execution.
Testing Best Practices and Procedures
Incremental Testing Approach
Start with simple workflows and progressively add complexity. This approach isolates issues and builds confidence in policy functionality.
Testing Progression:
Single User, Single Document - Basic PDD submission and processing
Single User, Complete Project - Full project lifecycle for one user type
Multi-User, Single Project - Role interactions and handoffs
Multi-User, Multiple Projects - Concurrent operations and scaling
Production Simulation - Full-scale testing with realistic data volumes
Dry-Run Artifacts and Validation
Guardian's dry-run mode creates artifacts that help validate testing results and provide audit trails for methodology compliance.
Dry-Run Artifacts:
Transaction Log: Mock blockchain transactions that would occur in production
Document Archive: Complete document history with version tracking
IPFS Files: Files that would be stored in distributed storage
Token Operations: Credit issuance and transfer records
Audit Trail: Complete workflow execution history

Test Data Management and Version Control
Maintain test datasets that evolve with your methodology. Version control ensures testing remains valid as policies change.
