It's a bit larger than just this function, as we have never exposed
any of the test modules in the docs.  Perhaps we could just add a line
in the section for injection points for this case.  At the end, I
don't want these additions to be an extra documentation burden if one
wants to add more tools, which may be in the scope of a bug fix as
that would just cause extra work.
