Test Strategy — TeamFlow

Quality & Security

1. Objective

The purpose of testing is to prove that TeamFlow reliably:

Preserves requirement history
Enforces authorization
Controls change workflows
Supports planning and QA traceability
Provides trustworthy management information

2. Test Levels

Unit testing
Repository testing
Integration testing
API contract testing
Frontend component testing
End-to-end testing
Security testing
Performance testing
Accessibility testing
Usability testing
Backup and recovery testing
User acceptance testing

3. Test Environments

Local

Used by developers for:

Unit tests
Component tests
Fast integration tests
Manual development checks

CI

Used for:

Formatting and linting
Unit tests
Integration tests
Build verification
Migration validation
Dependency scan
Selected end-to-end tests

QA

Used for:

Full workflow testing
Regression testing
Browser testing
Security checks
UAT preparation

Demo

Contains seeded, repeatable data for CTO demonstration with reset capability.

4. Unit Testing

Backend Unit Tests

Must cover:

Requirement creation and submission validation
Review transitions and approval rules
Approved-version immutability
New version creation from change requests
Change request transitions and impact analysis
Separation of duties enforcement
Task and test transitions
Release readiness calculation
Audit event creation

Frontend Unit/Component Tests

Must cover:

Required field validation
Role-based action visibility
Status badges and state rendering
Approval forms and workflows
Version comparison rendering
Impact total calculation and display
Error handling and messages
Confirmation dialogs
Empty states and loading states

5. Integration Testing

Integration tests must use a real PostgreSQL test database.

Test:

Database migrations
Constraints enforcement
Transactions and rollback behavior
Repository operations
Optimistic locking
Current approved version uniqueness
Audit log persistence
Query filtering and pagination
Project isolation

Critical Transaction Test

A comprehensive test that:

Approves a requirement version
Stores approval record
Creates immutable snapshot
Sets current approved version
Creates audit event
Intentionally fails one step
Verifies no partial state remains (rollback works)

6. API Contract Testing

Verify all endpoints return correct status codes
Validate response structures match contract
Test pagination parameters and sorting
Verify error responses follow standard format
Test trace ID inclusion in all responses
Verify optimistic locking conflicts return 409
Test immutability protection returns correct error

7. End-to-End Testing

Critical workflows to test:

Create → Submit → Review → Approve requirement
Create change request on approved version
Link tasks and tests to requirement versions
Approve change, verify new version created
Mark tests REVIEW_REQUIRED when requirement changes
Release readiness calculation

8. Security Testing

Verify cross-project data isolation
Test role-based access control
Verify unauthorized access is denied
Test separation of duties (self-approval prevention)
Verify password hashing
Test session expiration
Verify audit logging of sensitive actions
OWASP Top 10 vulnerability scanning
SQL injection prevention
XSS prevention

9. Performance Testing

List endpoints return < 2s for 95th percentile
Detail endpoints return < 2s for 95th percentile
Version comparison returns < 3s
Dashboard queries return < 5s
System supports 100 concurrent users
Identify and resolve performance regressions

10. Test Coverage Goals

Critical business logic: > 95% code coverage
Authorization logic: > 90% code coverage
API endpoints: > 85% coverage
Workflow state machines: > 95% coverage
Data validation: > 90% coverage

11. Test Data and Demo Scenario

Use repeatable seeded data
Demo scenario can be reset with a command
Include all 7 demo user roles
Demonstrate complete workflow from requirement to release
Show change request approval and new version creation
