Swift parser + mock generator

Rubicon generates spys for protocol. Generating methods for parent protocol is not supported.

Example

input:

protocol Car {

    var name: String? { get }
    var color: Int { get set }

    func go()
    func load(with stuff: Int, label: String) throws -> Int
    func isFull() -> Bool

}

Spy

output:

class CarSpy: Car {

    var name: String?
    var color: Int

    struct Load {
        let stuff: Int
        let label: String
    }

    var goCount = 0
    var load = [Load]()
    var isFullCount = 0
    var isFullReturn: Bool

    init(color: Int, isFullReturn: Bool) {
        self.color = color
        self.isFullReturn = isFullReturn
    }

    func go() {
        goCount += 1
    }

    func load(with stuff: Int, label: String) {
        let item = Load(stuff: stuff, label: label)
        load.append(item)
    }

    func isFull() -> Bool {
        isFullCount += 1
        return isFullReturn
    }
}

Mock

output:

class CarStub: Car {

    var name: String?
    var color: Int

    var isFullReturn: Bool

    init(color: Int, isFullReturn: Bool) {
        self.color = color
        self.isFullReturn = isFullReturn
    }

    func go() {
    }

    func load(with stuff: Int, label: String) {
    }

    func isFull() -> Bool {
        return isFullReturn
    }
}

Dummy

output:

class CarDummy: Car {

    var name: String? {
        fatalError()
    }
    var color: Int {
        get {
            fatalError()
        }
        set {
            fatalError()
        }
    }

    func go() {
        fatalError()
    }

    func load(with stuff: Int, label: String) {
        fatalError()
    }

    func isFull() -> Bool {
        fatalError()
    }
}

Usage in tests:

let carSpy = CarSpy()

...

XCTAssertEqual(carSpy.goCount, 1)
XCTAssertEqual(carSpy.load.count, 1)
XCTAssertEqual(carSpy.load[0].stuff, 2)
XCTAssertEqual(carSpy.load[0].label, "name")

CLI

Rubicon cli can generate mocks for every protocol in folder. Script runs through every swift file and find every protocol definition. Result is printed at standard out.

example:

$ ./rubicon --spy .

Options:

--mocks path - generates spies (deprecated)

--spy path - generates spies

--stub path - generates stubs

--dummy path - generates dummies

Xcode extension

Xcode extension can generate Spy for every or selected protocol in current file. Spy can be written to source file or pasteboard.
