These are fall-back expectations that you can use when none of the other more specific expectations apply. The disadvantage is that you may get a less informative error message.

expect_true(object, info = NULL, label = NULL)

expect_false(object, info = NULL, label = NULL)

Arguments

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.

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.

Details

Attributes are ignored.

Examples

expect_true(2 == 2) # Failed expectations will throw an error
# NOT RUN { expect_true(2 != 2) # }
expect_true(!(2 != 2)) # or better: expect_false(2 != 2) a <- 1:3 expect_true(length(a) == 3) # but better to use more specific expectation, if available expect_equal(length(a), 3)
