xctest 使用 NSPredicate 最终替换 Quick/Nimble

Question

我正在尝试将下面的测试用例从 quick/nimble 转换为 xctest：

expect(foundation.appGuid).toEventually(equal(guidValue))

以下是我正在使用但测试崩溃的代码：

let successPredicate = NSPredicate(format: "SELF MATCHES %@", guidValue)
    expectation(for: successPredicate, evaluatedWith: foundation.appGuid) {
      return foundation.appGuid == guidValue
    }

    waitForExpectations(timeout: 5) { (error) -> Void in
      if error != nil {
        XCTFail("foundation.appGuid NOT Equal to guidValue")
      }
    }

我在上面的代码中做错了吗？

Answer 1

这行得通：

let successPredicate = NSPredicate(format:  "SELF == %@", self.guidValue)
    expectation(for: successPredicate, evaluatedWith: foundation.serviceConfig.appGuid) {
      return foundation.serviceConfig.appGuid == self.guidValue
    }

    waitForExpectations(timeout: 5) { (error) -> Void in
      if error != nil {
        XCTFail("foundation.serviceConfig.appGuid NOT Equal to guidValue")
      }
    }
