C# Selenium WebDriverWait 似乎没有在等待
[英]C# Selenium WebDriverWait doesn't appear to be waiting
问题描述
我正在尝试测试我正在执行搜索的页面。 执行搜索后，我首先获取 table 元素，获取 table 行，然后从行中获取一个或多个行来完成我的断言，从而拉出 SearchResults。
我尝试以多种不同的方式使用 WebDriverWaits，但均未成功。 我设法从搜索结果中找到 select 项目的唯一可靠方法是使用 Thread.Sleep(3000)。 我们正在为我们的表格使用 PrimeNG 库。 正在加载的特定表非常大，因此需要进行一些等待
Selenium 信息：
- Selenium 版本：3.141.0
- Web 驱动类型：ChromeDriver (89.0.4389.2300)
- Web驱动版本：
浏览器信息：
- 浏览器类型：Chrome
- 浏览器版本：90+（在开发机器上）
Web 驱动程序初始化代码：我通过创建单独的页面对象和页面驱动程序来拆分我的页面和自动化代码。 这以SpecFlow Books 示例为模型

BasePage.TableLines()方法可以使用显式等待：
public virtual IEnumerable<IWebElement> TableLines()
{
var wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(30));
var locator = By.CssSelector("table > tbody > tr");
return wait.Until(ExpectedConditions.PresenceOfAllElementsLocatedBy(locator));
}
这假设在加载数据时对表进行了某种更改。 在不知道结果加载时表格会发生什么的情况下，这就是我所能提供的。
如果在滚动时动态添加表格行，那最终会是一个完全不同的解决方案。
