How to Use a State Transition Table in Testing?

Software testing as a part of IT sphere handles a great amount of information. Firstly, a specialist should get acquainted with the project documentation for the qualitative and effective execution of the certain tasks.

Also, it is important to possess a good theoretical basis, to get familiar with the additional techniques and practices, to learn more and more principles of the software testing types. Software testing company promotes the professional growth of its employees in all possible ways.

  • An event (an operation which modifies the current system state)
  • An action (takes place out of the system)
  • The following state (caused by the event)

A table clearly illustrates all possible combinations of the transition states in the form of a list. The scenarios of the system activity during the incorrect data input or the previous actions cancellation are also contained here.

With the help of transition table, one may detect such combinations of the system states changes which were not specified in the requirements and specification. It is of great importance to reveal them before the indirect beginning of the code writing.

The main disadvantage of the transition table is its size. A table may be too large because of the significant amount of the states and events which may permanently change.

Whether it is automated testing or manual testing, a specialist should use the appropriate principles and methods of checking.
