pybuild and testing pytest plugins

[Scott Talbert <swt@techie.net>]

When packaging a pytest plugin and wanting to run the plugin's unit tests 
during the build process, the plugin usually has to be installed before 
running the tests, otherwise pytest cannot find the plugin.  This seems to 
require workarounds such as this [1].

Is there any way to avoid this with pybuild or is such a workaround really 
necessary?

Thanks,
Scott
