These functions are designed to be used inside the tests in your Shiny app package.
Usage
expect_shinytag(object)
expect_shinytaglist(object)
expect_html_equal(ui, html, ...)
expect_running(sleep, R_path = NULL)Arguments
- object
the object to test
- ui
output of an UI function
- html
deprecated
- ...
arguments passed to
testthat::expect_snapshot()- sleep
number of seconds
- R_path
path to R. If NULL, the function will try to guess where R is.
Details
expect_running() only checks that an app can be launched: it starts a
background R process that runs run_app() and verifies that the process is
still alive after sleep seconds. It does not request any page, exercise
the server logic, or detect runtime errors that happen after start-up. A
passing expect_running() therefore means "the app starts and stays up", not
"the app works".
