Quality Assurance Company: State Transition Testing Technique
Each interactive software program transitions from one state to another. If you change the option set offered to the user, or the screen image is changed, it means that the program state changes too. Specialists of quality assurance company can advise you on this topic in a more comprehensive and detailed manner. Just come in contact with them and you will acquire the necessary knowledge in the shortest time possible.
The simplest example is the menu. After starting the program it has an only list of commands. After choosing a command from the list the program state changes and based on this new state of the app, other command bars appear on the Menu. In addition, the information shown on the screen also changes: the data-entry forms are displayed, etc.
Quality assurance companies are systematically asked to reduce time to market for all kinds of software applications, ensure optimal test coverage and accelerate software development process…and solve many other problems of yours so that you can be happy with your “creation”.
You should test each option offered by the program, every menu command. For example, command 15 may be available in the mode, which becomes accessible when using command 14 and 27. In this case, the command 15 needs to be tested twice – in both modes. However, there can be too many the menu commands and various program modes as well as transitions paths to these modes therefore it is hardly possible to test them all: the keypad will be used up before you complete all possible tests. Accordingly, selecting the tests to be needed to verify execution paths in the program, you had better consider the following criteria:
- Test all of the most probable sequences of user actions.
- If it can be assumed that the user’s actions in one mode may affect the presentation of data or a set of capabilities offered by the program in a different mode, you should test this dependence.
- In addition to carrying out the most basic tests – one of those which were described above is to be run on the program in any mode, randomly choosing the way of the program’s implementation.
As a matter of fact, almost all types of businesses and all sizes of companies cannot do without software testing services and use them as often as possible. Most of the firms and enterprises own IT products which could crack too soon and be accessed by hackers if not examined thoroughly on regular basis.
