There is another way also,
Create the same site with the same template as their on your development environment.
Take the library files I mean copy from Site Assets, Style Library, Site Pages & Master pages by opening it with Internet Explorer from development environment & paste it to testing environment.
Master Pages you need to take by mapping your local machine to network drive since we do not have direct rights to that pages. You need to open up from there and copy it from master page gallery of development and paste it to your testing site master page gallery.
And lastly you need to take the stp's of the sharepoint lists and libraries from development environment and upload it to the testing environment.
