* Extension of our previous work [6] for test data generation for data flow testing by adding a new approach for infeasible path detection.
* Extension of our previous implemented tool (ETODF) [24] for test data generation for data flow testing by adding a new component for infeasible path detection.
Each infeasible path can be divided into a set of feasible paths using the following method.
It is supposed that after the resolution of the relaxed linear program, which does not consider the battery's capacity, we will find a set of infeasible paths. Each infeasible path begins and returns to the depot in order to make trips A,B, ..., G Figure 3 includes an example illustrating the correction of infeasible routes based on the heuristic described above.
For the future development, the proposed algorithm will be able to handle uncertainties such as infeasible path and obstacle avoidance.
First, BEVs' range limit is considered as travel distance such that any path whose distance is greater than its range limit (referred to as infeasible paths) would not be chosen if the existing charging facility could not help finish the trip.
Compared to searching for a standard number of generations, an average of 30-75% of total computation was avoided in test programs with infeasible paths, and no feasible paths were missed due to early termination.
However, in this study, Weyuker observed a large proportion of infeasible paths in data-flow testing.
One of the pitfalls of structural testing is the problem of infeasible paths. We might expect similar infeasible connections if objects were integrated with structural criteria.
Finally eliminate infeasible paths; add other important paths; and generate test cases to make each path can be executed.
