Mock functions in a package.

Source: R/mock.R
with_mock.Rd

[Deprecated]

with_mock() and local_mock() are deprecated in favour of with_mocked_bindings() and local_mocked_bindings().

These functions worked by using some C code to temporarily modify the mocked function in place. This was an abuse of R's internals and it is no longer permitted.

Usage

with_mock(..., .env = topenv())

local_mock(..., .env = topenv(), .local_envir = parent.frame())

Arguments

...

named parameters redefine mocked functions, unnamed parameters will be evaluated after mocking the functions

.env

the environment in which to patch the functions, defaults to the top-level environment. A character is interpreted as package name.

.local_envir

Environment in which to add exit handler. For expert use only.

Value

The result of the last unnamed parameter
