record_test: Launch test event recorder for a Shiny app

Description

Once a recording is completed, it will create or append a new shinytest2 test to the testthat test_file.

Usage

record_test(
  app = ".",
  ...,
  name = NULL,
  seed = NULL,
  load_timeout = NULL,
  shiny_args = list(),
  test_file = "test-shinytest2.R",
  open_test_file = rlang::is_interactive(),
  allow_no_input_binding = NULL,
  record_screen_size = TRUE,
  run_test = TRUE
)

Arguments

app

A AppDriver object, or path to a Shiny application.

...

Must be empty. Allows for parameter expansion.

name

Name provided to AppDriver. This value should be unique between all tests within a test file. If it is not unique, different expect methods may overwrite each other.

seed

A random seed to set before running the app. This seed will also be used in the test script.

load_timeout

Maximum time to wait for the Shiny application to load, in milliseconds. If a value is provided, it will be saved in the test script.

shiny_args

A list of options to pass to runApp(). If a value is provided, it will be saved in the test script.

test_file

Base file name of the testthat test file.

open_test_file

If TRUE, the test file will be opened in an editor via file.edit() before executing.

allow_no_input_binding

This value controls if events without input bindings are recorded.

• If TRUE, events without input bindings are recorded.

• If FALSE, events without input bindings are not recorded.

• If NULL (default), if an updated input does not have a corresponding input, a modal dialog will be shown asking if unbound input events should be recorded.

See AppDriver$set_inputs() for more information.

record_screen_size

If TRUE, the screen size will be recorded when initialized and changed.

run_test

If TRUE, test_file will be executed after saving the recording.

Uploading files

Files that are uploaded to your Shiny app must be located somewhere within the tests/testthat subdirectory or available via system.file().

Files that are uploaded during recording that do not have a valid path will have a warning inserted into the code. Please fix the file path by moving the file to the tests/testthat subdirectory or by using system.file(). After fixing the path, remove the line of warning code.
