MockNetworking

MockNetworking is a Swift package allowing the replaying of mock responses to network requests through Apple Networking API’s by tying into the URLProtocol system.

Installation

MockNetworking is available for integration into Xcode through the Swift Package Manager. Point to https://github.com/Machx/MockNetworking.git in Xcode when adding the new package.

Basic Usage

To setup a mock response you simply need to register the response and then unregister the class when appropraite. In the example below we’ll setup a response for 1 test.

let url = try XCTUnwrap(URL(string: "https://wwww.apple.com"))
let response = try XCTUnwrap(HTTPURLResponse(url: url,
                    statusCode: 200,
                    httpVersion: HTTPURLResponse.HTTP_1_1,
                    headerFields: nil))

MockURLProtocol.register(response: response, for: url)
defer {
    MockURLProtocol.unregister()
}

This uses HTTPURLResponse, there is also a custom api available.

let url = try XCTUnwrap(URL(string: "https://wwww.apple.com"))
let mockResponse = MockPropertyResponse(url: url,
                    status: 200,
                    headerFields: [:])

MockURLProtocol.regigsterMock(response: mockResponse, for: url)
defer {
    MockURLProtocol.unregister()
}

The register api both registers MockURLProtocol with the URLProtocol system if it isn’t already registered and stores the prepared response for the given url.
