Performing Regression Test of windPRO

Introduction

What is Regression Testing?:

'Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.'

Regression Testing is done all the time by the windPRO software development team. Whenever some feature has been added or changes, it has to ensured that the this changes does not influence the way windPRO in any negative way. Performing this test manually can be quite an extensive job. Over the years some procedures and tools have been designed. The purpose of this document is to describe how windPRO end-users can benefit from some of these tools.

Regression Testing as a tool for end-users

The windPRO Calculation Tester is a small tool delivered together with windPRO. It allows anybody the design a windPRO project and use this project to perform regression testing.

The basic flow is:

• Design a simplified project with some data and calculations typical for your normal work-flow
• Run the project through the calculation tool and save the results for future reference

This can be beneficial on several occasions:

• After installing windPRO upgrades (New version or Service Pack)
• After installing Windows Updates
• After Switching to a new setup
  • New PC / OS
  • Rearranging the organization of windPRO data
