XCUI测试失败，原因是异步等待失败：30秒超出超时，有达不到预期

Question

 let webViewsQuery = app.webViews
    let emailOrPhoneTextField = webViewsQuery/*@START_MENU_TOKEN@*/.textFields["Email or phone"]/*[[".otherElements[\"Sign in – Google accounts\"].textFields[\"Email or phone\"]",".textFields[\"Email or phone\"]"],[[[-1,1],[-1,0]]],[0]]@END_MENU_TOKEN@*/
    let exists = NSPredicate(format: "exists == TextField")
    expectation(for: exists, evaluatedWith: emailOrPhoneTextField, handler: nil)
    waitForExpectations(timeout: 30, handler: nil)
    emailOrPhoneTextField.tap()

异步等待失败：超过超时30秒，无法实现的期望：“期待的对象谓词exists == 1‘电子邮件或电话’文本字段”通过FASTLANE扫描运行时，

Answer 1

那是因为你从来没有满足您的期望（与expectation.fulfill()法）。使用XCTWaiter如果你不关心期待实现。

Answer 2

这难道不是只是你需要让你的期望评价为真？

let exists = NSPredicate(format: "exists == true")

要么

let exists = NSPredicate(format: "exists == 1")
