People でログ計測テストをできるようにした話

詳細 ## WHY Testing logs is very hard and very fragile ## WHAT Make logs testable in UITest ## Usage 1. setup `TrackLogServer` ```swift override func setUp() { super.setUp() // endpoint: POST `http://localhost:9080/log_cache` TrackLogServer.shared.start() } override func tearDown() { super.tearDown() TrackLogServer.shared.stop() } ```
log ```bash Test Suite 'Selected tests' started at 2019-09-03 15:07:05.644 Test Suite 'namecard-scannerUITests.xctest' started at 2019-09-03 15:07:05.645 Test Suite 'TrackLogServerTest' started at 2019-09-03 15:07:05.645 Server has started ( port = 9080 ). Try to connect now... endpoint: http://localhost:9080["/log_cache"] ```
2. capture your log ```swift public static func send(eventName: String, parameters: [String: Any]) { Analytics.logEvent(eventName, parameters: formatValue(parameters: parameters)) #if DEBUG // send to POST `http://localhost:9080/log_cache` TestLogUploader.sendLogCache(eventName: eventName, parameters: parameters) #endif } ```
log ```bash 📝 log. { source: "firebase", track_event: { event_name: "action_tap", appendix1: "start_button", appendix2: "", appendix3: "" } } ```
3. run UITest and check log ```swift func test_log_firstLaunch() { app.launch() waitForElementToAppear(app.buttons["getStartedButton"], timeout: 10) app.buttons["getStartedButton"].tap() sleep(5) let firstLaunch = TrackLogServer.shared.cache .filter { $0.source == .firebase } .filter { $0.trackEvent.eventName == "action_tap" } .filter { $0.trackEvent.appendix1 == "start_button" } XCTAssertEqual(firstLaunch.count, 1) } ``` これは アプリ起動直後の "Getting Started" ボタンをタップした際に、 ```json { "event_name": "action_tap", "appendix1": "start_button" } ``` というログが取られたかのテストケース

Aspects使ってますよね？

https://github.com/steipete/Aspects

Aspects hooks deep into the class hierarchy and creates dynamic subclasses, much like KVO. There's known issues with this approach, and to this date (February 2019) I STRICTLY DO NOT RECOMMEND TO USE Aspects IN PRODUCTION CODE. We use it for partial test mocks in, PSPDFKit, an iOS PDF framework that ships with apps like Dropbox or Evernote, it's also very useful for quickly hacking something up.

Value SemanticsとReferenceSemanticsについて

Value Semanticsを持たない問題

Swiftの標準ライブラリはほぼすべてがValue型 SwiftはCopy On Writeという仕組みでValue型の配列を実現している

iOSSnapshotTestCase

スナップショットテストが多用されていているので参考になるはず。
