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 = base::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`.
