如何验证单元格在我的 UI 测试中是否可见

How can I verify a cell is visible in my UI Test

我试图在 UITest 中断言双击主页图标会将我的 table 视图滚动回顶部。

我假设这个模式是加载视图,滚动,断言它不能出现,点击主页并断言现在可以。

我有这样的东西

   let username = "...."
    let password = "...."

    app.launch()

    let loginPage = app.otherElements["login page"]
    loginPage.waitForExistence()

    let usernameInputField = app/*@START_MENU_TOKEN@*/.webViews.textFields["Email address"]/*[[".otherElements[\"bfx_login\"].webViews",".otherElements[\"Log in to OneHub | Recognition\"].textFields[\"Email address\"]",".textFields[\"Email address\"]",".webViews"],[[[-1,3,1],[-1,0,1]],[[-1,2],[-1,1]]],[0,0]]@END_MENU_TOKEN@*/
    usernameInputField.tap()
    usernameInputField.typeText(username)

    let passwordInputField = app/*@START_MENU_TOKEN@*/.webViews.secureTextFields["Password"]/*[[".otherElements[\"bfx_login\"].webViews",".otherElements[\"Log in to OneHub | Recognition\"].secureTextFields[\"Password\"]",".secureTextFields[\"Password\"]",".webViews"],[[[-1,3,1],[-1,0,1]],[[-1,2],[-1,1]]],[0,0]]@END_MENU_TOKEN@*/
    passwordInputField.tap()
    passwordInputField.typeText(password)

    loginPage.buttons["Log In"].tap()

    let tabBarController = app.tabBars["home_tabBarController"]
    tabBarController.waitForExistence()

    let activityFeed = app.tables["Activity Feed"]
    activityFeed.waitForExistence()

    app.swipeUp()

    XCTAssertFalse(activityFeed.cells.element(boundBy: 0).isHittable)

    let homeButton = tabBarController.children(matching: .button).element(boundBy: 0)
    homeButton.waitForExistence()
    homeButton.doubleTap()

    XCTAssertTrue(activityFeed.cells.element(boundBy: 0).isHittable)

除了能够对单元格进行断言之外,一切正常。我不相信

    XCTAssertFalse(activityFeed.cells.element(boundBy: 0).isHittable)

    XCTAssertTrue(activityFeed.cells.element(boundBy: 0).isHittable)

正在按照我的预期工作。

如何断言 table 视图中的单元格可见?

就检查某物是否可见而言,you want to use isHittable in conjunction with exists. See also 。 像这样:

element.exists && element.isHittable

你说过 isHittable 对你不起作用,你能解释一下它不起作用的原因吗?
