Question

我想知道如何将Selenium中C#的这两种通用方法转换为Java版本，因为我没有Java的任何经验：

public static IWebElement WaitAndFindElement(Func<IWebDriver, IWebElement> expectedCondtions, int timeoutInSeconds)
{
    WebDriverWait webDriverWait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
    webDriverWait.IgnoreExceptionTypes(typeof(NoSuchElementException));
    return webDriverWait.Until(expectedCondtions);
}

public static ReadOnlyCollection<IWebElement> WaitAndFindElements(Func<IWebDriver, ReadOnlyCollection<IWebElement>> expectedCondtions, int timeoutInSeconds)
{
    WebDriverWait webDriverWait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
    webDriverWait.IgnoreExceptionTypes(typeof(NoSuchElementException));
    return webDriverWait.Until(expectedCondtions);
}

Answer 1

第一个： //等待元素变为可点击

public static void WaitAndClick(WebElement elementToBeClicked) throws InterruptedException, IOException {
    try {
        WebDriverWait wait = new WebDriverWait(driver, 20);
        WebDriverWait wait1 = new WebDriverWait(driver, 20);

        wait.until(ExpectedConditions.visibilityOf(elementToBeClicked));
        wait1.until(ExpectedConditions.elementToBeClickable(elementToBeClicked));

        elementToBeClicked.click();

    } catch (Exception e)

    {
        Logger_Info("Element not clicked yet. waiting some more for " + elementToBeClicked);

        if (waitCounter < 3) {
            waitCounter++;
            WaitAndClick(elementToBeClicked);
        }
        waitCounter = 0;
    }

第二名：

// Wait for an element to become visible

public static void WaitUntilVisible(WebDriver driver, WebElement elementToBeClicked) throws InterruptedException, IOException {
    try {


        WebDriverWait wait = new WebDriverWait(driver, 20);
        WebDriverWait wait1 = new WebDriverWait(driver, 20);

        wait.until(ExpectedConditions.visibilityOf(elementToBeClicked));
        if (!elementToBeClicked.isDisplayed()) {
            Logger_Info("Element not visible yet. waiting some more for " + elementToBeClicked);
            if (waitCounter < 3) {
                waitCounter++;
                WaitUntilVisible(elementToBeClicked);
            }
            waitCounter = 0;
        }

    } catch (Exception e)

    {
        Logger_Info("Handling exception");
    }
}

Answer 2

这是一个非常直接的转换：Func =＆gt; java.util.function.Function IWebDriver =＆gt; WebDriver（对于网络元素相同）typeof =＆gt; .class。共：

public static WebElement waitAndFindElement(Function<WebDriver, WebElement> expectedCondtions, int timeoutInSeconds) {
    WebDriverWait webDriverWait = new WebDriverWait(driver, timeoutInSeconds).ignoring(NoSuchElementException.class);
    return webDriverWait.until(expectedCondtions);
}

public static List<WebElement> waitAndFindElements(Function<WebDriver, List<WebElement>> expectedCondtions, int timeoutInSeconds)
{
    WebDriverWait webDriverWait = new WebDriverWait(driver, timeoutInSeconds).ignoring(NoSuchElementException.class);
    return Collections.unmodifiableList(webDriverWait.until(expectedCondtions));
}

Java中的通用FindElement方法
