UAT vs Other Testing

Testing Type	Who	Focus	When
Unit Testing	Developers	Code components	During development
Integration Testing	QA	System interfaces	After unit tests
System Testing	QA	End-to-end functionality	After integration
UAT	Business Users	Business requirements	Before go-live
Regression Testing	QA	No new defects	After changes

UAT Planning Process

1. UAT Strategy

Define:

Scope: What features/modules to test
Approach: Script-based, exploratory, or hybrid
Environment: UAT environment requirements
Data: Test data requirements
Timeline: Start/end dates, milestones
Resources: Testers, support

UAT Scope Example:

## In Scope
- New checkout flow (guest and registered)
- Payment processing (credit card, PayPal)
- Order confirmation and emails
- Order history viewing

## Out of Scope
- Admin functions (tested by IT)
- Existing functionality not changed
- Performance testing (separate test)

2. Entry Criteria

Before UAT begins:

All development complete
Unit and integration tests passing
System testing complete with no critical bugs
UAT environment set up and stable
Test data prepared
User credentials created
UAT scripts reviewed and approved
Training completed (if needed)

3. Exit Criteria

UAT is complete when:

All critical and high-priority test cases passed
No open critical or high-severity defects
Medium/low defects documented with workarounds
Sign-off from business stakeholders
Go-live readiness confirmed

Defect Severity

Severity	Definition	UAT Impact
Critical	System unusable, data loss	UAT blocked, immediate fix required
High	Major feature broken, no workaround	Must fix before go-live
Medium	Feature issues with workaround	Should fix, can go-live with workaround
Low	Minor issues, cosmetic	Nice to fix, doesn't block go-live

Best Practices

Planning

✅ Do:

Involve business users early in planning
Create realistic test data
Allow buffer time for defect fixes
Train testers on new features
Document expected results clearly

❌ Don't:

Wait until last minute to start UAT
Use production data with sensitive info
Skip test case review
Underestimate time needed
Forget about regression testing

Execution

✅ Do:

Track progress daily
Triage defects quickly
Re-test after fixes
Document everything
Communicate blockers immediately

❌ Don't:

Let testers create ad-hoc tests only
Ignore "minor" issues
Skip re-testing after fixes
Delay communication of issues
Rush sign-off
