If functional testing is referred as black box..how can it be done on unit test level?
Preparing myself for ISTQB, I found a bit odd many things in their textbooks. E.g. they call black box testing as functional testing when you are not concerned with structured but only observe the ouput based on inputs.
But later they say that functional testing is done at levels..well, how can I do unit testing without the knowledge how it works if I can just see it (and must see it). It is white box but then it is in the conflict..
How to use lists in equivalence partitioning?
I have read that equivalence partitioning can be used typically for intervals or lists, e.g. I assume it can be used for every set of inputs.
Anyway if the requirement says that allowed colors are (RED,BLUE,BLACK, GREEN), I cannot treat them like a list, right? I mean, testing one of them would not be enough because developers most likely used some switch-case and thus it is not real “set” where one could represent also the others.
So how it is meant with lists?
Which code is better for branch prediction optimization?
Given branch prediction, and also the effect of compiler optimizations, which code tends to offer superior performance?
Pairwise testing, not possible to say which combinations is faulty?
Let’s say I have 4 (A,B,C,D) parameters with 3 possible values, also 81 unique combinations. With e.g. orthogonal array, I will end up with 9 test cases, each combining 3 pairs. But that means that if one test case fails, I do not know which combination in the test case is faulty, right? Whether values of A,B or A,C or BC. Just wanted to be sure I understood it well.
“Generators are function derivatives”
I am reading this article on a new feature of ECMAscript 6, generators, that are landing in the V8 JavaScript interpreter. Not too far from the top, the author suggests an analogy:
Is context-driven testing suitable for all projects?
One thing I cannot find anywhere is: is this approach limited to non-critical software? Because in critical (or just when customer wants us to follow his rules) we have no freedom in testing and just follow the procedures.
Am I right?
Array Multiplication and Division
I came across a question that (eventually) landed me wondering about array arithmetic. I’m thinking specifically in Ruby, but I think the concepts are language independent.
