#### _Who's mocking who now?_
This is yet another mocking library.
Unlike other mocking libraries, this one allows you to keep your module structure as it is!
Just add the `{.mockable.}` pragma to your exported procs, compile with the `--define:mock` flag and you're good to go!
The pragma turns any proc annotated with it into a variable that can be assigned to.
You can then "mock" procs by simply assigning a different procedure to that variable.
**Note: This currently does not work with generics! I'm looking into how to get there but it's hard**
# Example
```nim
# get5Module.nim
proc get5*(): int {.mockable.} = 5 # Can be replaced
```
```nim
# add5Module.nim
import ./get5Module
proc add5*(x: int): int = x + get5()
```
```nim
import ./add5Module
import ./get5Module
import std/[sugar, unittest]
suite "Test add5":
# Important for the teardown in order to "reset" the mocks
let get5Original = get5
teardown:
get5 = get5Original # "Resets" the mock to provide the normal behaviour again
test """
Given get5 returns 5
When calling add5 with 10
Then it should return 15
""":
check add5(10) == 15
test """
Given get5 returns 10
When calling add5 with 10
Then it should return 20
""":
get5 = () => 10
check add5(10) == 20
test """
Given get5 not being mocked and so it should returns 5
When calling add5 with 10
Then it should return 15 again
""":
check add5(10) == 15
```
