XCTestテストにおけるsetup, teardownの便利なクラス

Last updated at Posted at 2016-06-15

2017/8/1追記

class func initialize() がdepricatedになりそうなのでちゃんとしたやつ

テストBundleのInfo.plistに

<key>NSPrincipalClass</key>
<string>Bundle名.クラス名(ここでいうTestSetup)</string>

TestSetup.swift

class TestSetup:NSObject,XCTestObservation {
    
    override init() {
        super.init()
        XCTestObservationCenter.shared().addTestObserver(self)
    }
    
    /// TestBundle開始時
    func testBundleWillStart(_ testBundle: Bundle) {
    }

    /**
     毎テストケース開始前
     */
    func testCaseWillStart(_ testCase: XCTestCase) {
    }
}

もっとすごい

あるとすごい便利 DBのセットアップとか最初にしておきたいとか
import XCTest

// ゴニョゴニョクラス
class TestSetup: XCTestCase,XCTestObservation  {
    override class func  initialize() {
        let me = TestSetup()
        let center = XCTestObservationCenter.sharedTestObservationCenter()
        center.addTestObserver(me)
    }
    
    func testBundleWillStart(testBundle: NSBundle) {
        //テスト開始前
    }
    func testBundleDidFinish(testBundle: NSBundle) {
        // テスト終了後
    }
    func testSuiteWillStart(testSuite: XCTestSuite) {
        // 各スイート開始前
    }
    
    func testSuiteDidFinish(testSuite: XCTestSuite) {
        // 各スイート終了後
    }
    func testCaseWillStart(testCase: XCTestCase) {
        // 各ケース開始前
    }
    func testCaseDidFinish(testCase: XCTestCase) {
        // 各ケース終了後
    }
}
すごい
