expect_that(object, condition, 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. |
---|---|
condition, | a function that returns whether or not the condition is met, and if not, an error message to display. |
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. |
the (internal) expectation result as an invisible list
This style of testing is formally deprecated as of the 3rd edition.
Use a more specific expect_
function instead.
fail()
for an expectation that always fails.
