| expect_is {testthat} | R Documentation |
Do you expect to inherit from this class?
Description
![[Superseded]](../help/figures/lifecycle-superseded.svg)
expect_is() is an older form that uses inherits() without checking
whether x is S3, S4, or neither. Instead, I'd recommend using
expect_type(), expect_s3_class(), or expect_s4_class() to more clearly
convey your intent.
Usage
expect_is(object, class, 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. |
