A spunky mocking library for Swift


Using Moxie

Let's say you have a protocol you want to mock.

protocol List {
    mutating func add(_ item: String)
    mutating func clear()

    func get(_ index: Int) -> String?

You can use Moxie to create a mock.

import Moxie

struct MockList: Mock, List {
    var moxie = Moxie()

    mutating func add(_ item: String) {
        record(function: "add", wasCalledWith: [item])

    mutating func clear() {
        record(function: "clear")

    func get(_ index: Int) -> String? {
        return value(forFunction: "get")

Then you can use it in your tests.

func testList() {

    var mockList = MockList()

    // verifying invocations

    XCTAssertTrue(mockList.invoked(function: "add"))
    XCTAssertEqual("one", mockList.parameters(forFunction: "add")[0] as? String)
    XCTAssertTrue(mockList.invoked(function: "clear"))

    // stubbing
    mockList.stub(function: "get", return: "first")

    XCTAssertEqual("first", mockList.get(0))
