Testing and Validation of the Migrated Web Application

Introduction

This document outlines the procedures for testing the migrated web application on Amazon Web Services (AWS) to ensure functionality, performance, and security. Thorough testing and validation are essential steps in the migration process to verify that the application operates as expected in the new environment.

Functional Testing

Step 1: Smoke Testing

  • Perform smoke testing to ensure basic functionality and navigation of the web application.
  • Verify that key features such as login, registration, and main user flows are working correctly.

Step 2: Regression Testing

  • Conduct regression testing to validate that existing functionality has not been adversely affected by the migration.
  • Re-run test cases covering critical business processes and user scenarios to detect any regression defects.

Step 3: User Acceptance Testing (UAT)

  • Engage stakeholders and end-users in UAT to validate that the migrated application meets business requirements and user expectations.
  • Solicit feedback from users regarding usability, performance, and any issues encountered during testing.

Performance Testing

Step 1: Load Testing

  • Perform load testing to evaluate the performance and scalability of the web application under expected and peak load conditions.
  • Use tools like Apache JMeter, Gatling, or AWS Load Testing Services (e.g., AWS Elastic Load Testing) to simulate concurrent user traffic and measure response times, throughput, and resource utilization.

Step 2: Stress Testing

  • Conduct stress testing to assess the resilience and stability of the application by subjecting it to extreme load and resource exhaustion.
  • Identify performance bottlenecks, scalability limits, and potential failure points under stress conditions.

Step 3: Capacity Planning

  • Analyze performance test results to determine the optimal capacity requirements for the application on AWS.
  • Scale resources such as EC2 instances, RDS databases, and load balancers to meet performance objectives and accommodate future growth.

Security Testing

Step 1: Vulnerability Scanning

  • Perform vulnerability scanning using automated tools (e.g., AWS Inspector, Nessus, OWASP ZAP) to identify security vulnerabilities and misconfigurations.
  • Address any identified vulnerabilities such as outdated software versions, insecure configurations, or common security issues.

Step 2: Penetration Testing

  • Conduct penetration testing (pen testing) to assess the resilience of the application against real-world cyber attacks and exploitation attempts.
  • Engage certified security professionals or ethical hackers to simulate attack scenarios and attempt to breach the application's defenses.

Step 3: Compliance Validation

  • Validate compliance with regulatory requirements and industry standards (e.g., PCI DSS, HIPAA, GDPR) by conducting compliance assessments and audits.
  • Ensure that security controls, data protection measures, and access controls align with applicable compliance frameworks.

Conclusion

By following the procedures outlined in this document for testing and validation of the migrated web application on AWS, you can ensure that the application meets functional requirements, performs optimally under load, and adheres to security best practices and compliance standards. Thorough testing is essential for mitigating risks and ensuring a successful migration outcome.
