线程“main”org.openqa.selenium.ElementNotVisibleException中的异常：元素当前不可见，因此可能无法与之交互

Question

*Exception in thread "main" org.openqa.selenium.ElementNotVisibleException: Element is not currently visible and so may not be interacted with*

Answer 1

您正在while循环内调用driver.close（）；，该循环将关闭浏览器。关闭浏览器时不能与元素交互。在测试完成后将其移动到。

另请注意，如果您希望在与元素交互之前确保该元素是可见的，请使用explicit wait

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement username = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Email")));
username.sendKeys(user_name);

这将等待长达10秒的元素可见。wait.tear也返回它所等待的元素。

WebDriverWait wait = new WebDriverWait(driver, 10); // initialize wait object

while ((nextLine = reader.readNext())!= null) {

    // locate and write to user name
    WebElement username = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Email")));
    username.clear();
    username.sendKeys(user_name);

    // locate and write to password
    WebElement password = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));
    password.clear();
    password.sendKeys(user_name);
}
