Developing an Information System
Testing (1 of 2)

Any new system needs to be thoroughly tested before being introduced.

First of all the system should be tested with normal data to see if it works correctly.
Secondly, the system is tested with data containing known errors to try and make it fail ('crash').
Thirdly, the system is tested with very large amounts of data to see how it can cope.

It is important that processing time and response rates remain acceptable with varying amounts of data.
