Test for output produced by print()
or cat()
. This is best used for
very simple output; for more complex cases use verify_output()
.
expect_output( object, regexp = NULL, ..., info = NULL, label = NULL, width = 80 )
object | Object to test. Supports limited unquoting to make it easier to generate readable failures within a function or for loop. See quasi_label for more details. |
---|---|
regexp | Regular expression to test against.
|
... | Arguments passed on to
|
info | Extra information to be included in the message. This argument is soft-deprecated and should not be used in new code. Instead see alternatives in quasi_label. |
label | Used to customise failure messages. For expert use only. |
width | Number of characters per line of output. This does not
inherit from |
The first argument, invisibly.
