What is LCSAJ Testing?

Image
LCSAJ testing requires a model of the source code which identifies control flow jumps (where control flow does not pass to a sequential statement). An LCSAJ (Linear Code Sequence and Jump) is defined by a triple, conventionally identified by line numbers in a source code listing: the start of the linear code sequence, the end of the linear code sequence, and the target line to which control flow is transferred. Test cases shall be designed to exercise LCSAJs. For each test case, the following shall be specified: - the input(s) to the component; - identification of the LCSAJ(s) to be executed by the test case; - the expected outcome of the test case.

What is State Transition Testing?

Image
State transition testing uses a model of the states the component may occupy, the transitions between those states, the events which cause those transitions, and the actions which may result from those transitions. The model shall comprise states, transitions, events, actions and their relationships.   The states of the model shall be disjoint, identifiable and finite in number.   Events cause transitions between states, and transitions can return to the same state where they began.   Events will be caused by inputs to the component, and actions in the state transition model may cause outputs from the component. The model will typically be represented as a state transition diagram, state transition model, or a state table. Test cases shall be designed to exercise transitions between states.   A test case may exercise any number of transitions.   For each test case, the following shall be specified: -   the starting state of the component  ...
