It extracts out common UI provided by shinytest and vdiffr.
You can install the released version of diffviewer from CRAN with:

This is a basic example which shows you how to solve a common problem:
library(diffviewer)
<- tempfile()
path1 writeLines(letters, path1)
<- tempfile()
path2 writeLines(letters[-(10:11)], path2)
visual_diff(path1, path2)
