C# Selenium WebDriver 开关/案例

Question

public enum ElementType
{
    Id,
    ClassName,
    Name,
    XPath,
    CssSelector,
    LinkText
}

public static class WebDriverExtensions
{

    public static void AssertElementDisplayed(this IWebDriver driver, ElementType elementType, string element)
    {
        if (elementType == ElementType.Id)
            Assert.IsTrue(driver.FindElement(By.Id(element)).Displayed);
        if (elementType == ElementType.ClassName)
            Assert.IsTrue(driver.FindElement(By.ClassName(element)).Displayed);
        if (elementType == ElementType.Name)
            Assert.IsTrue(driver.FindElement(By.Name(element)).Displayed);
        if (elementType == ElementType.XPath)
            Assert.IsTrue(driver.FindElement(By.XPath(element)).Displayed);
        if (elementType == ElementType.CssSelector)
            Assert.IsTrue(driver.FindElement(By.CssSelector(element)).Displayed);
        if (elementType == ElementType.LinkText)
            Assert.IsTrue(driver.FindElement(By.LinkText(element)).Displayed);
    }

    public static void WaitForElementPresent(this IWebDriver driver, ElementType elementType, string element)
    {
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));

        if (elementType == ElementType.Id)
            wait.Until(ExpectedConditions.ElementIsVisible(By.Id(element)));
        if (elementType == ElementType.ClassName)
            wait.Until(ExpectedConditions.ElementIsVisible(By.ClassName(element)));
        if (elementType == ElementType.Name)
            wait.Until(ExpectedConditions.ElementIsVisible(By.Name(element)));
        if (elementType == ElementType.XPath)
            wait.Until(ExpectedConditions.ElementIsVisible(By.XPath(element)));
        if (elementType == ElementType.CssSelector)
            wait.Until(ExpectedConditions.ElementIsVisible(By.CssSelector(element)));
        if (elementType == ElementType.LinkText)
            wait.Until(ExpectedConditions.ElementIsVisible(By.LinkText(element)));
    }

我正在寻找将其转换为 switch case 语句的最佳方法，而不是使用 if 语句，但不确定实现此目的的最佳方法。我需要一种简单的方法来在 By.Id、By Class、By.Name 等之间切换...

无需传递所有这些额外信息。只需传递一个 By 定位器，它就会处理其余的事情并使代码变得更加简单。

public static void AssertElementDisplayed(this IWebDriver driver, By locator)
{
    Assert.IsTrue(driver.FindElement(locator).Displayed);
}

和

public static void WaitForElementPresent(this IWebDriver driver, By locator, int timespan)
{
    new WebDriverWait(driver, TimeSpan.FromSeconds(timespan)).Until(ExpectedConditions.ElementIsVisible(locator));
}
