A basic mocking module, inspired by Python's unittest.mock and implemented with Cassette.
using SimpleMock
f(x) = x + 1
mock(+) do plus
@assert plus isa Mock
@assert f(0) != 1 # The call to + is mocked.
@assert called_once_with(plus, 0, 1)
end
mock((+, Float64, Float64) => Mock((a, b) -> 2a + 2b)) do plus
@assert 1 + 1 == 2
@assert 2.0 + 2.0 == 8
@assert called_once_with(plus, 2.0, 2.0)
