Mac OS上的Safari的WebDriver wait命令失败

Question

我有脚本登录到一个站点，然后等待主页按钮得到加载。我设置了fluentwait以等待元素可见。但WebDriver不会等待并立即失败,因为home按钮未加载。

By usernameInput = By.name("User”);
By passwordInput = By.name("Password”);
By loginButton = By.xpath("//input[@value='Sign In']”);
String URL = “https://demotest.mytest.com/"

WebDriver driver = new SafariDriver();
driver.get(URL);
driver.manage().window().maximize();
setText(usernameInput,”User1");
setText(passwordInput,”User1");
clickOnElement(loginButton);
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver);

以下抛出错误-

理想情况下，它应该等待Home按钮显示。但它正在失败。这在Windows上的Chrome,Firefox,IE,Edge都能用,但在Mac上的Safari上却不行。

看起来像是把WebDriverWait和FluentWait类混在一起了。

请尝试使用以下命令：

WebDriverWait wait = new WebDriverWait(driver, 15, 100);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@title='Home']")));
