我正在使用下面的代码来刺激双击按钮,但是,我收到的编译错误指向了操作,但我不知道如何修复它。
Actions act = new Actions(driver);
act.doubleClick(driver.findElement(By.id("dijit_form_Button_0_label"))).build().perform();
logger1.info("Logout Successful");
org.testng.TestNGException:

有什么想法吗?

您可以尝试使用javascript触发doubleclick事件。 这就是我从selenium触发click事件的方法,我猜你可以调整它以触发doubleclick
public static void phantomClick (WebDriver driver, WebElement element){
final String script = "function ghostclick(el){var ev = document.createEvent(\"MouseEvent\");ev.initMouseEvent(\"click\",true ,true,window,null,0,0,0,0,false,false,false,false,0,null);el.dispatchEvent(ev);} return ghostclick(arguments[0])";
((JavascriptExecutor) driver).executeScript(script, element);
}

TestNGException
不是编译错误。这是TestNG抛出的RuntimeException
。在这种情况下,TestNG抛出了异常,因为它无法实例化类testNG.RAD3398LogoutTwiceTest&#34;。
原因如下:
Caused by: java.lang.NullPointerException
at org.openqa.selenium.interactions.Actions.<init>(Actions.java:44)
at testNG.RAD3398LogoutTwiceTest.<init>(RAD3398LogoutTwiceTest.java:25)
这意味着在初始化/构建RAD3398LogoutTwiceTest
的实例时,调用Actions
的构造函数,然后在第44行抛出NullPointerException
。
如果你看一下Actions.java:44,你会看到this.mouse = ((HasInputDevices) driver).getMouse();
。即初始化失败,因为driver
为null
。
确保在初始化new Actions(driver);
之后发生driver
之类的任何语句,否则您的测试类将无法初始化,而TestNG将抛出异常。
解决此问题后,您的双击语句应该执行。

简化为:
((JavascriptExecutor) driver).executeScript("document.getElementById('map_container').dispatchEvent(new Event('dblclick'));");
