I have got question below in a mock exam.
Which of the following series of state transitions below will provide 0-switch coverage?
What does switch coverage mean? I have found that this is a part of State Transition Testing and 0-switch(branch coverage) coverage is to execute each loop once, but couldn't see background logic.
Solution is A, B, E, B, C, F, F, but it isn't important in this case.
Chow's switch coverage describes how you cover a state transition model. A "switch" in this context is a state in between your beginning state and your end state in your traversal of the model. So 0-switch coverage means that you exercise every direct transition possible in the model. 1-switch coverage means you allow one state between your start and end state.
In a very simple example, say A->B->C->D, 0-switch coverage would be A->B, B->C, and C->D. 1-switch coverage would be A->B->C and B->C->D.
