I thought black box could still consider some design specs.

Deeann 12 months ago

Wait, are we sure black box never uses code? Sounds off.

Yolando 12 months ago

C is spot on, white box does measure code coverage!

Rosalia 12 months ago

I disagree, both can use models in some cases.

Black box doesn't use code, that's true.

I thought white box techniques were more about the internal workings of the software, which makes option C sound plausible, but I'm not entirely sure.

I practiced a similar question, and I believe white box testing does involve looking at the code. So, option A seems off to me.

I'm a bit confused about the definitions. I remember something about code coverage, but I can't recall if black box testing measures that.

Lewis 1 year ago

I think black box testing focuses on inputs and outputs without looking at the code, right? So maybe option C is correct?

Definitely the one about assessing testers on failure detection. That kind of metric can create a blame culture and discourage open reporting.

Okay, I've got a strategy for this. I'll focus on identifying the key characteristics of a project phase, then evaluate each option against that criteria. Methodical approach should help me nail this.

This is a good one. I remember from the course materials that the Check phase is all about monitoring and evaluating the results of the changes made in the Do phase. Regular reviews are essential to ensure you're on the right track and can make adjustments as needed.
