In software testing field, information can be represented in various forms. It may be schema, table, diagram, notation, etc. Every specialist from software testing company chooses the form of representation which is the easiest for him to comprehend.

For example, state-transition testing presupposes the usage of either state-transition diagram or table. It does not matter what representation form to use. The core point is to perform functional testing[1] effectively.

State-transition table consists of several parts. There are four columns.

What Are State-Transition Table Columns?

The table demonstrates all possible state-transition combinations in a form of list. It contains the scenario of both valid and invalid input conditions. Besides that, the creation of state-transition table may detect the combinations which were not defined in the requirement specifications. It is very important to discover such issues before coding process starts.

The main disadvantage of state-transition table is its size. It may be very large, as number of states and events increases fast in a complex system.

Either it is automated testing[2] or manual testing[3], a specialist should apply proper principles and use the techniques which will accelerate the checking process, help to detect the majority of serious bugs and prevent possible difficulties.
