call-expectations {mockery} | R Documentation |
Together with mock
can be used to verify whether the
call expression (expect_call
) and/or argument values
(expect_args
) match the expected.
expect_call(mock_object, n, expected_call) expect_args(mock_object, n, ...) expect_called(mock_object, n)
mock_object |
A |
n |
Call number or total number of calls. |
expected_call |
Expected call expression; will be compared unevaluated. |
... |
Arguments as passed in a call. |
With expect_called
you can check how many times has the mock
object been called.
library(testthat) # expect call expression (signature) m <- mock() with_mock(summary = m, summary(iris)) # it has been called once expect_called(m, 1) # the first (and only) call's arguments matches summary(iris) expect_call(m, 1, summary(iris)) # expect argument value m <- mock() a <- iris with_mock(summary = m, summary(object = a)) expect_args(m, 1, object = a) # is an equivalent to ... expect_equal(mock_args(m)[[1]], list(object = a))
