What Must Both Software Testers and Investigators Do?

It is of common knowledge that web site testing, desktop testing and mobile application testing require critical thinking and open mind.

The task of a tester is not just to find out if everything operates properly and according to the requirements. Testers also must enquire what happens under various unexpected and unconsidered conditions.

A professional software testing company usually tries to check all feasible cases, even if they are believed to be unlikely.


It is wise to elaborate test cases for various situations, in particular, for the worst ones. One should wonder what happens if several errors occur or several tasks are performing simultaneously. A software tester, as well as an investigator, must elaborate theories and possible scenarios.

In Order to Create Good Scenarios a Tester and an Investigator Must:

  • carefully study the object and the situation;
  • consult various experts; the experts are the developers, coworkers and domain specialists in case of mobile testing, desktop testing or web site testing.

It is a good idea to ask the software engineers what the worst scenarios are in their opinion. As a rule, such events are considered to be hardly probable and their scenarios are not thought out.

Testers should pay close attention to these cases. Otherwise users may face serious errors in production and the software won’t be successful.
