Applications of Path Testing in Software Testing Methodologies

Applications of Path Testing

Integration, Coverage and Paths in called Components
Path testing methods are mainly used in unit testing, especially for new software
The new component is first tested as an independent unit with all called components and co-requisite components replaced by stubs. A simulator of low-level components that is more reliable than the actual component
Path testing clarifies the integration issues
C1 coverage at the system level ranges from 50% to 85%
We gave no statistics for C2 coverage in system testing because it is impossible to monitor C2 coverage without disrupting the system's operation
Note:
Co-requisite: A formal course of study required to be taken simultaneously with another
New Code:
New code should always be subjected to enough path testing to achieve C2
Stubs are used where it is clear that the bug potential for the stub is significantly lower than that of the called components
Old, trusted components will not be replaced by stubs
Some consideration is given to paths within called components
Typically, we will try to use the shortest entry/exit path that will do the task
Maintenance:
There is a great difference between maintenance testing and new code testing
Maintenance testing is a completely different situation
It involves modifications which are accommodated in the system, as required
Path testing is used firstly on the modified component
Rehosting:
Path testing with C1+C2 coverage is a powerful tool for rehosting old software
We get a very powerful, effective, rehosting process when C1+C2 coverage is used in conjunction with automatic or semiautomatic structural test generators
Software is rehosted because it is no longer cost effective to support the environment in which it runs
The objective of rehosting is to change the operating environment and not the rehosted software
Rehosting from one COBOL environment to another is easy by comparison
Rehosted software can be modified to improve efficiency and/or to implement new functionality, which had been difficult in the old environments
The test suites(collection) and all outcomes of the old environment become the specification for the rehosted software
