Test Phases

1

Unit Testing

During Build

Development Team

Validate individual components work as designed. Focus on custom code, BAdIs, user exits, and configuration settings.

Focus Areas:Individual objects, custom code, configurations
Automation Potential:High (80%+)
2

Integration Testing

Post-Build

Technical Team

Verify end-to-end process flows across modules. Test interfaces with external systems and middleware.

Focus Areas:Cross-module flows, interfaces, APIs
Automation Potential:Medium (50-60%)
3

System Testing

Pre-UAT

Test Team

Execute complete business scenarios including exception handling and negative testing.

Focus Areas:Complete business processes, edge cases
Automation Potential:Medium (40-50%)
4

User Acceptance Testing

4-6 weeks pre-go-live

Business Users

Business users validate system meets requirements. Sign-off required for go-live.

Focus Areas:Real-world scenarios, usability
Automation Potential:Low (manual)
5

Performance Testing

Parallel to UAT

Technical Team

Validate system performance under expected and peak loads. Identify bottlenecks.

Focus Areas:Load, stress, volume, scalability
Automation Potential:High (automated tools)
6

Cutover Testing

2-4 weeks pre-go-live

Project Team

Rehearse complete cutover process including data migration, system configuration, and go-live activities.

Focus Areas:Migration scripts, cutover runbook
Automation Potential:Medium

Test Data Management

Data Strategies

  • Production Copy:Full or partial copy with data masking
  • Synthetic Generation:Tool-generated realistic test data
  • Subset Extraction:Slice of production for specific scenarios
  • Manual Creation:Hand-crafted for edge cases

Data Masking Requirements

  • Personal identifiable information (PII)
  • Financial account numbers
  • Customer names and addresses
  • Employee salary and HR data
  • Vendor banking details
  • Credit card and payment data

GDPR/Privacy: Ensure test data complies with data protection regulations. Never use unmasked production data in non-production systems.

Defect Management

Severity Classification

CriticalSystem down, no workaround, blocks go-live
HighMajor function impaired, workaround difficult
MediumFunction impaired, workaround available
LowMinor issue, cosmetic, can defer

Go-Live Defect Criteria

  • 0 Critical defectsMandatory
  • 0 High defects without workaroundMandatory
  • <5 High defects with workaroundRecommended
  • <20 Medium defectsRecommended
  • All deferred defects documentedMandatory

Go-Live Readiness Criteria

Testing Checkpoints

  • UAT sign-off from all business owners
  • All critical business processes tested
  • Performance tests meet SLA requirements
  • Security penetration testing complete
  • Integration tests pass with all external systems
  • Cutover rehearsal successful (2+ times)
  • Rollback procedure tested and documented

Supporting Documentation

  • Test summary report with pass/fail metrics
  • Defect status report and closure plan
  • Performance test results and baselines
  • User training completion records
  • Cutover runbook with timing estimates
  • Support team readiness confirmation
  • Hypercare plan and escalation matrix
