使用 Selenium Java 测试用例调用 CLICK 时获取“org.openqa.selenium.ElementClickInterceptedException”

Question

我在 Katalon Selenium IDE 中使用以下 java 代码。

import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.ui.*;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

  public static void setUp() throws Exception {
 System.setProperty("webdriver.chrome.driver", "C:\\Users\\myuser\\Downloads\\chromedriver_win32\\chromedriver.exe");
 driver = new ChromeDriver();
    driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
  }


public static void testQScan() throws Exception {
    driver.get("https://qualysguard.myorg.com/fo/login.php?idm_key=saml2_78743hhh43");
    WebElement element = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='userNameInput']")));
    System.out.println("Title of the page is 8 -> " + driver.getTitle());
    driver.findElement(By.linkText("Scans")).click();
    System.out.println("Title of the page is 9 -> " + driver.getTitle());
}

启动基本 URL 后，应该单击“扫描”选项卡。这工作正常，使用 Selenium/Katalon 浏览器插件 IDE 播放时，“扫描”选项卡会被点击。

但是，运行导出的 java 代码会出现以下错误：

输出：

Title of the page is 8 -> Dashboard
Exception in thread "main" org.openqa.selenium.ElementClickInterceptedException: element click intercepted: Element <a onclick="javascript: showProcessing('...');" href="/fo/tools/module_landing.php?module=prod_scans" class="module-link">Scans</a> is not clickable at point (180, 100). Other element would receive the click: <div id="page-loading-mask" style="visibility: visible;">...</div>

请提供有关如何克服错误的建议。

在扫描选项卡的浏览器上查看源具有以下条目：

<div id="top_modules_bar">

Answer 1

使用 Actions 类或 javascript 执行器：

Actions act =  new Actions(driver);
act.moveToElement(driver.findElement(By.linkText("Scans"))).click().perform();

或者

try {
     driver.findElement(By.linkText("Scans")).click();
  } catch (Exception e) {
     JavascriptExecutor executor = (JavascriptExecutor) driver;
     executor.executeScript("arguments[0].click();", driver.findElement(By.linkText("Scans")));
  }
