Yes I think so.
I use static default values for all members of ConfigParams and I 
instantiate ConfigParams in my unit tests, so I assume that the 
variable would be global there.
The code looks like:

unittest {

   string[] args = [
     "binaryFileName",
     "--bindAddresses=0.1.2.3;4.5.6.7",
     "--bindHTTPPort=80",
     "--bindHTTPSPort=443",
     "--configFile=testfiles/test.conf.sdl",
     "--verbosityLevel=detailed",
   ];

   ConfigParams configParams;  // default values for parameters
   configParams.readFromAll(args); // values read from 
command-line arguents

   // assertion checks here
}

What do you suggest? Should I move all default initializations to 
a constructor?
Thank you for your response.
