expect_named {testthat} | R Documentation |
You can either check for the presence of names (leaving expected
blank), specific names (by suppling a vector of names), or absence of
names (with NULL
).
expect_named(object, expected, ignore.order = FALSE, ignore.case = FALSE, info = NULL, label = NULL)
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. |
expected |
Character vector of expected names. Leave missing to
match any names. Use |
ignore.order |
If |
ignore.case |
If |
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. |
