Why this topic?

Consider the following „typical” requirements

I want a cat.The cat should have 4 legs, 2 eyes and 2

ears.The cat should be provided in 2 weeks

Because of this, you need to understand what are you going to test:• You need to understand requirements• You need to „see” the business context of the system and the whole project• You need to understand the purpose of the products and its impact on testing

Ok, you may say – requirements should clearly say what to test

Business knowledge and testing

The problem is: The requirements are often poorly documented The requirements are often missing The requirements are often inconsistent

The second problem is that to claim requirements as not good, you must know the business area

In other case, how can you know that you are testing „the right cat”?

The system should be usable

The system should be fast

Results:Branch and till balancing not working correctly Branch reporting not working correctlyDevices not working as supposedTransactions taking too longBusiness rules… what business rules???
