try to put this before the main of your application:

   "version(unittest){} else"

it looks like the default unittest config implies the switch 
"-main".

Are you sure? The error message states exactly this. Could you 
reduce the project to a single file and upload it somewhere (e. 
g. github).

I am getting the same error for my projects. I tried prefacing my 
main functions with the version(unittest) {} else snippet (which 
we really shouldn't have to do!!!) but anyway that didn't change 
the behavior of dub test at all.

It is a quite old thread but the issue is still relevant. In the 
first post, there is a dependency to poodinis which defines in 
the test package a void main function.

Maybe main functions in dependencies causing this issue. Which 
dependencies do you have?

Kind regards
