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.

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.
