vtest provides a platform for testing graphical output from R packages. It is made up of three main parts:
-
Functions that you run to construct your visual tests suite:
vcontext()
,save_vtest()
,end_vcontext()
-
vtest()
to run a suite of visual tests and save the results locally -
Functions to compare runs of tests and display differences.
Currently vtest only works with ggplot2.
