expect_receives: Expect a given function to be receive specified arguments...

In robertzk/rum: Mocha-inspired mocking and stubbing (http://github.com/robertzk/rum)

Description

This assertion checks that a given function is called with specified arguments during the execution of another expression.

Usage

expect_receives(function_name, arguments, expr, times = 1)

Arguments

function_name	name. Either the name of the function, or a package function given by the :: or ::: operators.
arguments	list. A subset of the arguments we expect the function to be called with.
expr	expression. An R expression that should somewhere during it execution call function_name.
times	integer. The number of times the function should be called with these arguments. By default, 1.

Value

NULL, invisibly, but an error if the expectation is not satisfied (i.e., function_name is not called).

Examples

# expect_receives(force, list(1), lapply(c(1,1), force), times = 2)
