I am working on testing technique for embedded system. To implement the testing technique, I have find some patterns regarding how the testing procedure should executed.
For evaluation I have to take an example and implement my idea on it. The example cover 75% of patterns but remaining 25% patterns are not present in the source code. For example I have considered "call by references of variables" but the source code does not have any variables which is used for call by references.
In this circumstances what should i do? Should I go for another example when those remaining patterns are present or just skip those patterns?
If I include another example then how can I evaluate with two examples?
I am not sure I understand your question, but in principle you should always test functionality, and not implementation. Test whatever makes sense to test for the API to perform the _actions_ you want, not to have the _implementations_ you expect.
Hope this helps.
I have a somewhat different view than Edgar. Both black box and white box testing are commonly used and both valid if the source/design information is available. The white box testing tests for conformance to specification and is primary, but black box testing takes advantage of knowing the implementation and thereby devising tests for common implementation errors as seen in related projects, so both approaches are valuable.
As to the original question, skipping the patterns if they don't apply sounds reasonable to me, but I and other readers would likely need more information to really know.
@Edgar Duenez-Guzman
In every research what we do is give a theory. It can be an equation, method, technique, procedure, comparison etc. Suppose I have given a theory so i need to prove that my theory whether it is correct or not. To do so, i find some example of that domain and implement my theory on it. isn't test functionality and implementation are same?
1. What Edgar Duenez-Guzman said.
2. Patterns are often things that do not show up in contiguous blocks of source code. I think you are chasing the wrong goal here. Give it up.
