I think you have to take a look at :
http://dlang.org/code_coverage.html

It seems you just have to call dmd with the module name and -cov 
option as parameter.

I used eclemma plugin for coverage highlighting on Eclipse, and a 
usefull feature is the capability to use layered result which 
allow you to increase the cover by using many configurations.

Unit tests with highlighting decrease a little the need of 
debuggers, because using asserts or conditions aren't harder to 
use break points.


Maybe it will be necessary to add names on tests.
