c# - Show winform during unit test -

i'm having bit of trouble showing winform during unit test. i'm using user validated testing procedure show user 2 different image segments captured during selenium ui testing , diff between them , allowing user pass or fail test based on whether or not images different.

i've created form 2 picturebox elements , added methods form allow form take in images require , load them picturebox , show form.

i've tried searching google + , can't find similar questions regarding this.

in test have:

var compareform = new plotcompare.plotcompare(); compareform.add_original_image(image1); compareform.add_diff_image(imagediff); compareform.show(); 

but .show(); call doesn't show form.

the issue can reasonably think of project i'm using class library because holds tests , therefore doesn't have main function can access.

would appreciate help, in advance.

i had use .showdialog() rather .show()
