我正在尝试使用 Selenium 测试按钮单击。我的第一页有一个 ID = HOME_START_BUTTON 的按钮。当我单击它时，我的应用程序会转到一个带有 ID = CONTACTS_ADD_BUTTON 按钮的页面。这是我必须测试的代码。

private static boolean checkPageContainsStartButton()
{
    // type search query
    // driver.findElement(By.name("q")).sendKeys("qa automation\n");

    //Use static finals for these button names
    WebElement startButton = driver.findElement(By.id("HOME_START_BTN"));
    if (startButton == null)
    {
        return false;
    }
    else
    {
        startButton.click();
    }

    WebElement myDynamicElement = (new WebDriverWait(driver, 30))
      .until(new ExpectedCondition<WebElement>(){
            @Override
            public WebElement apply(WebDriver d) {
            return d.findElement(By.id("CONTACTS_ADD_BTN"));
    }});

    WebElement addButton = driver.findElement(By.id("CONTACTS_ADD_BTN"));
}

Test failed.

如果我注释掉，我的测试通过

WebElement addButton = driver.findElement(By.id("CONTACTS_ADD_BTN"));

所以基本上，当我单击按钮时，Selenium 似乎无法在浏览器窗口上看到新的小部件

You need to add a wait till the first button action is done. Use a default constant across all waits in your app. DEFAULT_RPC_WAIT, DEFAULT_SCREEN_WAIT etc. It would help to know where you have set up your waits by using Constants instead of just magic numbers.

Also reference GWT guidelines w.r.t to Selenium - https://developers.google.com/web-toolkit/doc/latest/DevGuideTestingRemoteTesting

  1. 你发布了， 但在你的代码中我看到：ID = HOME_START_BUTTON
    By.id("HOME_START_BTN")

  2. 来自 WebDriver 接口对 findElement 方法的注释：
    findElement不应该用于查找不存在的元素，而是使用并断言零长度响应。findElements(By)

    /**
 * Find the first {@link WebElement} using the given method.
 * This method is affected by the 'implicit wait' times in force at the time of execution.
 * The findElement(..) invocation will return a matching row, or try again repeatedly until 
 * the configured timeout is reached.
 *
 * findElement should not be used to look for non-present elements, use {@link #findElements(By)}
 * and assert zero length response instead.
 *
 * @param by The locating mechanism
 * @return The first matching element on the current page
 * @throws NoSuchElementException If no matching elements are found
 * @see org.openqa.selenium.By
 * @see org.openqa.selenium.WebDriver.Timeouts
 */
WebElement findElement(By by);
