![]() “lamp off – push on-switch – lamp on – pushoff-switch – lamp off” 1-switch coverage: “lamp off – push on-switch – lamp on”Īnd “lamp on – push off-switch – lamp off”.0-switch coverage: “push on-switch” and “push off-switch”.Coverage of all states: “lamp off” and “Lamp on”.The combinations of “n” transitions – this can be used to ensure “n-1”-coverageįor our lamp example the test situations for different coverage levels are:.The individual transitions – this can be used to ensure 0-switch coverage.The individual states – this enables testing if all states can be reached.Test situations for state transition testing can be: Usually only 0-switch coverage and 1-switch coverage are applied, sometimes 2-switch. For example, “2-switch coverage” tests combinations of 3 consecutive transitions. If a higher number of consecutive transitions are tested, we speak of “n-switch coverage” where ‘n’ is the number of consecutive transitions minus 1. If sequences of two transitions are tested, so all combinations of two consecutive transitions are tested, we achieve “1-switch coverage”. 0-switch coverage means that we do not focus on testing consecutive transitions. If every single transition is tested, we achieve “0-switch coverage”. The level of test coverage is related to the number of consecutive transitions that are covered. Since a state transition diagram doesn’t show invalid transitions, only test cases with valid transitions can be derived from a state transition diagram.Ī state table indicates valid transitions and invalid transitions, so a state table can be used for testing both. Within state transition testing you can choose to test individual transitions or combinations of transitions. Above the resulting states, the actions may be added. When the transition is invalid, it is shown as a hyphen (‘-‘). Mentioning the action with the resulting state is optional. When a transition is valid the resulting state is shown in the corresponding cell of the table. The left side of the table contains the states, and the top contains the events. The transitions between states can also be shown in a state table as shown below. If the off-switch is pushed, the electric current is cut and the lamp is turned off. If the on-switch is pushed, the electric current is enabled and the lamp is turned on. The correct behavior of the system is described in a state transition diagram that gives an overview of all states, the transitions between these states, the events that trigger transitions and the actions that result from events. State transition testing is often used to test embedded software that controls machines, but also to test menu-structures in GUI-based systems or other types of systems that have distinct states and a process for getting from one state to another. Multiple coverage levels can be achieved, indicated as n-switch coverage. ![]() State transition testing is used to test whether the system correctly responds to events for example by transitioning from one state to another. Tests are designed to execute valid and invalid state transitions. ![]() State Transition testing is a process-oriented test design technique that focuses on states, events that initiate a transition to another state and actions resulting from such events. State Transition diagram(s) and state table(s) State Transition Testing Test approachįunctionality testing, process flow testing, menu-structure testing, and more With state transition testing several distinct coverage levels can be achieved. These models can also be used to design tests. State-based models are used to define this behavior.
