Testing Responsibilities

There are important differences between developer responsibilities (internal QA - Quality Assurance) and client responsibilities (User Acceptance Testing - UAT) in software development. Both types of testing are critical for the success of a project, and it’s important that both parties understand their responsibilities:

Internal QA (Quality Assurance) – Software Developer’s Responsibility

Goal: Ensure the software functions correctly, meets requirements, and is free of critical defects before it reaches the client. Who Does It? Our internal QA team, developers, and testers.
Focus Areas:
  • Functional Testing – Ensuring each feature works as intended.
  • Regression Testing – Making sure new changes don’t break existing functionality.
  • Performance Testing – Checking speed, stability, and scalability.
  • Security Testing – Identifying vulnerabilities.
  • Bug Fixing & Refinements – Reporting, prioritizing, and fixing defects
Outcome: A stable, well-tested product ready for client review.

User Acceptance Testing (UAT) – Client’s Responsibility

Goal: Verify that the software meets business needs and works as expected in real-world scenarios.

Who Does It? End-users, business stakeholders, or client-side testers.

Focus Areas:

  • Business Process Validation – Ensuring workflows align with actual business operations.
  • Real-World Use Cases – Testing scenarios based on daily user activities.
  • Usability & Experience – Ensuring ease of use and efficiency.
  • Final Approval for Deployment – Deciding if the software is ready to go live.

Outcome: Confirmation from the client that the system meets their requirements and is ready for production.

Key Difference

  • Internal QA is about ensuring technical quality and catching defects
  • UAT is about ensuring the software works for the client’s specific needs and is ready for real-world use.
