testApp: Run tests for a Shiny application

In shinytest: Test Shiny Apps

Run tests for a Shiny application

Description

Run tests for a Shiny application

Usage

testApp(
  appDir = ".",
  testnames = NULL,
  quiet = FALSE,
  compareImages = TRUE,
  interactive = is_interactive(),
  suffix = NULL
)

Arguments

appDir	Path to directory containing a Shiny app (e.g. app.R) or single interactive .Rmd.
testnames	Test script(s) to run. The .R extension of the filename is optional. For example, "mytest" or c("mytest", "mytest2.R"). If NULL (the default), all scripts in the tests/ directory will be run.
quiet	Should output be suppressed? This is useful for automated testing.
compareImages	Should screenshots be compared? It can be useful to set this to FALSE when the expected results were taken on a different platform from the one currently being used to test the application.
interactive	If there are any differences between current results and expected results, provide an interactive graphical viewer that shows the changes and allows the user to accept or reject the changes.
suffix	An optional suffix for the expected results directory. For example, if the suffix is "mac", the expected directory would be mytest-expected-mac.

See Also

snapshotCompare() and snapshotUpdate() if you want to compare or update snapshots after testing. In most cases, the user is prompted to do these tasks interactively, but there are also times where it is useful to call these functions from the console.
