Regression testing
How do you write a regression testing? There is a running system but the system needs to be updated. Some of the updates are creating a web base system that can be accessed anytime and documents can be viewed up to one year old and doesn't take long to bring the saved documents up. I was needing help in how to do the regression testing.

Thanks. We'll let you know when a new response is added.

There is a raft of tools that provide regression testing services. The answer primarily depends on the platform that the app is running on.

A very basic answer is:

The working app is run with a predefined set of test data that will exercise all or most of the applicataion logic. The outputs of the app are collected. That is files, print outs, screen images, etc.

The changes are made to the application and tested. When you are satisfied that it is working run it with the test data used against the working app. The data MUST be the same so the exact images must be captured.

Compare the outputs from the original and changed runs. Explain ALL the differences. Hopefully they are what the changes were expected to do. If not, the changes created a bug.

Good luck
Dave
