I am unsure concerning general policy related to org-babel test, so the 
following is rather discussion than a direct request to change the test.

Is there a way to avoid dependency on remote resources? My concern is 
test results affected by network issues. In addition, more required 3rd 
party tools means less probability that a developer after modification 
of generic babel code noticed that the changes break D backend because 
missing tool on the development machine. I have no idea how much efforts 
is required to create a mock for isolated environment.

Another point is that missed dub binary is not reflected in test report. 
If `skip-unless' feature of ert is available in Emacs-26 then it should 
be used.
