java - 第二个复选框单击被忽略

Question

以下代码忽略第二个复选框单击。有谁知道为什么以及如何解决？在最后一行设置断点以查看复选框仍处于选中状态...

private final static String CHECKBOXBUTTON_URL = "https://www.w3schools.com/html/tryit.asp?filename=tryhtml_Checkbox";
private final static String RESULT_IFRAME = "iframeResult";
private final static By CHECKBOX = By.xpath("/html/body/form/input[2]");

@Test
public void checkbox()
{
    System.setProperty("webdriver.edge.driver", "MicrosoftWebDriver.exe");
    WebDriver driver = new EdgeDriver();
    FluentWait<WebDriver> wait = new WebDriverWait(driver, 0);
    driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
    wait.withTimeout(Duration.ofSeconds(10)).pollingEvery(Duration.ofMillis(200));

    driver.get(CHECKBOXBUTTON_URL);
    wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(RESULT_IFRAME));

    driver.findElement(CHECKBOX).click();
    wait.until(ExpectedConditions.elementToBeSelected(CHECKBOX));

    driver.findElement(CHECKBOX).click(); // this click is ignored

    driver.quit(); // break here; checkbox is still checked (but shouldn't)...
}

由于浏览器的动画时间间隔在框中显示复选标记，它被忽略。

driver.findElement(CHECKBOX).click();
wait.until(ExpectedConditions.elementToBeSelected(CHECKBOX));
//Something can be coded here    
driver.findElement(CHECKBOX).click(); // this click is ignored

您可以选择以下两种语句中的任何一种。

添加 1 或 2 秒的硬等待。使用Thread.sleep(2000). 这将允许过渡动画稳定下来。
在目标复选框上使用isSelected()方法，以确定它是否真的被选中。如果选择该方法，则返回 true，否则返回 false。

您需要注意以下几个事实：

FluentWait：除非绝对必要，否则使用WebDriver实例的FluentWait的量身定制的特化，而不是FluentWait<WebDriver>use 。WebDriverWait()
您需要使用所需的timeOutInSeconds值配置WebDriverWait ，例如 5, 10, 15 但不是0。
pageLoadTimeout()：尽量避免配置pageLoadTimeout()，除非测试规范明确提及相同的内容。

一旦您switch()到达所需的帧而不是等待，ExpectedConditions如下所示：elementToBeSelected()elementToBeClickable()

new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@name='vehicle' and @value='Car']"))).click();

您优化的代码块如下：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Checkbox_Click {

    public static void main(String[] args) {

        System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
        WebDriver driver = new FirefoxDriver();
        driver.get("https://www.w3schools.com/html/tryit.asp?filename=tryhtml_Checkbox");
        new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframeResult"));
        new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@name='vehicle' and @value='Car']"))).click();
    }
}

您可以使用索引切换帧并使用它移动到第二帧，然后对复选框执行操作。

private final static String CHECKBOXBUTTON_URL = "https://www.w3schools.com/html/tryit.asp?filename=tryhtml_Checkbox";
private final static By CHECKBOX = By.xpath("//input[@name='vehicle' and @value='Car']");

@Test
public void checkbox()
{
    System.setProperty("webdriver.edge.driver", "MicrosoftWebDriver.exe");
    WebDriver driver = new EdgeDriver();
    FluentWait<WebDriver> wait = new WebDriverWait(driver, 0);
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.switchTo().frame(1); 
    //   new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframeResult"));
     WebElement element=driver.findElement(By.xpath("//input[@name='vehicle' and @value='Car']"));
    element.click();
    wait.until(ExpectedConditions.elementToBeSelected(element));
    element.click();
}

    driver.quit(); // break here; checkbox is still checked (but shouldn't)...
}
