I came across this recent question, originally only tagged with c#.
OP is particularly interested in how unit-test -friendly his code is, and what could be done to improve on that aspect.
The unit-testing tag doesn't seem appropriate in this case, since my understanding of that tag's applicability implies that the post contains unit tests.
Would a testability tag be useful?
I'm giving this status-declined since it is a meta-tag, and we're already in the process of burninating a number of them. Even if it were already around, it would've still been one of the tags to go.
While testability may be a valid concern in a peer review, it adds about no value to the question itself, it's a meta-tagging. In fact any question that will ever be tagged testability should just explicitly state in the question body that a - or the main - concern is the testability of the code.
Some of you will say, that this also applies to readability and I will say: Yes, this applies to all meta-tags, but why make the same mistake as before?
The initial goal for tags was searchability (another of those *ability words). And all these meta-tags provide no value for that :(
Testability is a valid concern in a peer review, having a testability tag would guide reviewers into writing their answers from a testability standpoint, just like the popular readability tag guides reviewers into addressing readability issues.
testability is more than just clean-code, and unit-testing is too vague.
There is nothing in the unit-testing wiki that makes me feel like it doesn't apply to the referenced question. What's the difference between unit-testing and testability? The wikis could be cleaned up to specify that unit-testing applies specifically to reviews of unit testing code and that testability applies to how testable code is, but I'm afraid that these two similar names (yet very different ideas) would be confused. It seems that having these two tags would just set us up for an eventual synonym made out of the despair of being unable to maintain them separately.
Yes!!

Tags are a means of connecting experts with questions they will be able to answer by sorting questions into specific, well-defined categories.
Tags can also be used to help you identify questions that are interesting or relevant to you.
Testability is very interesting/relevant to me, it seems the worst code by smart people I see so far is testable code. I want to track what CR comes up with as a community to address the inherent difficulties in writing good testable code.
