A spunky mocking library for Swift
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
mockList.add("one")
mockList.clear()
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))
}
