xctest使用NSPredicate最终替换Quick / Nimble

Question

我正在尝试将以下测试用例从quick / nimble转换为xctest：

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

以下是我正在使用的代码，但测试崩溃了：

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

这有效：

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")
      }
    }
