Compare current and expected snapshots

This compares current and expected snapshots for a test set, and prints any differences to the console.

snapshotCompare(
  appDir,
  testnames = NULL,
  autoremove = TRUE,
  images = TRUE,
  quiet = FALSE,
  interactive = is_interactive(),
  suffix = NULL
)

snapshotUpdate(appDir = ".", testnames = NULL, quiet = FALSE, suffix = NULL)

Arguments

appDir: Directory that holds the tests for an application. This is the parent directory for the expected and current snapshot directories.
testnames: Name or names of a test. If NULL, compare all test results.
autoremove: If the current results match the expected results, should the current results be removed automatically? Defaults to TRUE.
images: Should screenshots and PNG images be compared? It can be useful to set this to FALSE when the expected results were taken on a different platform from the current results.
quiet: Should output be suppressed? This is useful for automated testing.
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.
