Selenium 脚本没有等待足够长的时间来达到显式等待中定义的时间

Question

我正在使用 TestNG 框架编写 selenium 脚本。在 selenium 抛出 NoSuchElement 异常之前，我已经将显式等待定义为 20 秒。但脚本在执行期间不会等待 20 秒，并在 41 毫秒内抛出异常。我希望此脚本在抛出任何异常之前等待（仅使用显式等待）或搜索 Web 元素 20 秒。

下面是脚本后面的执行结果。

public class para {
WebDriver driver;

@BeforeClass
void InvokeFF() {
    System.setProperty("webdriver.gecko.driver",
            "C:/Users/Vinay/workspace_n/EGuru/drivers/geckodriver.exe");
    driver = new FirefoxDriver();
    // driver.get("http://seleniumpractise.blogspot.in/2016/08/bootstrap-dropdown-example-for-selenium.html");
    System.out.println("Firefox invoked");
    System.out.println("Firefox thread:" + Thread.currentThread().getId());

}

@Test
void Auto() throws Exception {
    WebDriverWait wait = new WebDriverWait(driver, 20);
    driver.get("file:///C:/Users/Vinay/Desktop/Upload1.html");
    WebElement elem = driver.findElement(By.xpath(".//*[@id='1']"));
    wait.until(ExpectedConditions.visibilityOfElementLocated(By
            .xpath(".//*[@id='1']")));
    elem.click();
    Runtime.getRuntime().exec("C:\Users\Vinay\Desktop\AutoUpload.exe");
}

Answer 1

WebElement elem = driver.findElement(By.xpath(".//*[@id='1']"));
wait.until(ExpectedConditions.visibilityOfElementLocated(By
        .xpath(".//*[@id='1']")));

以上两行需要顺序颠倒。您正在尝试不等待地获取元素，然后告诉 webdriver 等到它到达那里。
