Hello,

Is grey box testing, simply in between white and black box testing?

[7cats]

I'm not familiar with the term, but intuitively it would seem to be a 'mixture' of white box and black box testing, since those terms are pretty much 'binary'.

Either you know what is 'in the box' (white) or do not know (black). 

So, I postulate that 'grey' would be doing both types of testing (seems redundant), or doing part of the testing black and part white, or having some 'black' boxes inside a bigger 'white' box.

Yes, this term is getting more popular. I was asked about this in my last interview.

Basically means that "some knowledge" of the internal workings of the system is known.

In Grey Box testing, you will not see the code, but you should know the code behavior, when doing some scenario's in your product.
