Details

Currently the following elements are available:

• call the call that was tested as an unevaluated call, but keep in mind that if you intend to evaluate this for a reference item the environment may not be the same so you could get different results (ls will provide more details)

• value the value that results from evaluating the test, note this is equivalent to using .new or .ref; note that the value is displayed using desc when viewing all of .NEW or .REF

• output the screen output (i.e. anything produced by cat/print, or any visible evaluation output) as a character vector

• message anything that was output to stderr, mostly this is all contained in the conditions as well, though there could be other output here, as a character vector

• conditions a conditionList containing all the conditions produced during test evaluation

• aborted whether the test call issues a restart call to the `abort` restart, as `stop` does.

Examples

## From the unitizer> prompt:
.NEW <- mock_item()  # .NEW is normally available at unitizer prompt
.NEW$call
.NEW$conditions
.NEW$value              # equivalent to `.new`
