- The approach seems usefull nice and we used a similar one in our paper:
- "A Formal Aprroach to Conformance testing, IWPTS 90" with the following
- modification of attributing traces (actually a test) with a cost function.
- Some traces are more critical than others.
-
- I would not mix up the work of engineers and testing. Of course engineers do
- there own part of testing/debugging, The main disadvantage is that during
- construction of the system a complete and corrrect system needs to be build.
- Not a system which passes 90% of the tests, since the tests may be wrong too.
-
- Realistic %BFA, seems to depend on field of application of the system,
- the quality of the tests, the available resources etc.
