REL08-BP02: Integrate functional testing as part of your deployment
Overview
Implement comprehensive functional testing as an integral part of your deployment pipeline to ensure that changes meet business requirements and maintain system functionality. Automated functional testing validates that applications work correctly from an end-user perspective before reaching production environments.
Implementation Steps
1. Design Functional Testing Strategy
- Define functional test categories and coverage requirements
- Establish test data management and environment preparation
- Design test case prioritization and execution strategies
- Implement test result analysis and reporting frameworks
2. Create Comprehensive Test Suites
- Develop unit tests for individual component validation
- Implement integration tests for service interaction validation
- Create end-to-end tests for complete user journey validation
- Design API tests for service contract validation
3. Implement Test Automation Framework
- Configure automated test execution in CI/CD pipelines
- Implement parallel test execution for faster feedback
- Design test environment provisioning and cleanup
- Establish test data seeding and management automation
4. Configure Test Environment Management
- Implement production-like test environments
- Configure environment isolation and resource management
- Design test environment provisioning and deprovisioning
- Establish test environment monitoring and maintenance
5. Establish Test Quality and Maintenance
- Implement test code quality standards and reviews
- Configure test flakiness detection and resolution
- Design test maintenance and update procedures
- Establish test performance optimization strategies
6. Monitor and Optimize Testing Performance
- Track test execution times and success rates
- Monitor test coverage and quality metrics
- Implement continuous improvement based on test analytics
- Establish testing ROI and effectiveness measurements
