No it never does, and perhaps it should, but that's up to Beman.

Why does it suggest that? It's perfectly acceptable, and common, to use
the dynamic runtime in a link library.

Ah, it's a presumption... What you are saying is that we should globally
mandate that tests be performed such that DLLs be tested only against
the dynamic runtime and and LIBs against the static runtime. What about
the users of LIBs that use the dynamic runtime? (I'm one of those)

1. Make sure that there are both <lib> and <dll> tests. (program_options
currently does it)
2. Run the test with "-sBUILD=debug release
<runtime-link>static/dynamic". Which will build 4 variants.
2b. Or if you are also interested in threading you can run the test with
"-sBUILD=debug release <runtime-link>static/dynamic
<threading>single/multi". Which will build 8 variants, if supported by
