Full Life-cycle Testing / Regression Testing

Every time a defect is fixed, a new feature is added or any other change is made to the system, there is a risk that existing and previously tested and working functionality and features of the system could be broken.

Regression testing is performed to ensure such changes and fixes don’t break existing functionality.

• Targeted regression testing appropriate to the level of risk
• Re-use of existing test assets and recommendations for test automation where appropriate
  

• Introduce fixes or new features without degrading existing functionality
