Java.IllegalMonitorStateException thrown because of Selenium webdriver code driver.wait(0)

问题

以下是代码的翻译部分：

  1. 我正在使用以下Selenium webdriver代码，并且在“driver.wait(0)”行收到异常。我使用等待语句等待弹出窗口加载并允许测试执行。
  3. 这是我的堆栈跟踪副本：
  5.     java.lang.IllegalMonitorStateException
  6.     	在java.lang.Object.wait(Native Method)中
  7.     	在Test.MounaTest.test(MounaTest.java:61)中
  8.     	...
  10. 这是代码：
  12.     package Test;
  13.     
  14.     // 由Selenium IDE生成
  15.     import org.junit.Before;
  16.     import org.junit.jupiter.api.AfterAll;
  17.     import org.junit.jupiter.api.BeforeEach;
  18.     import org.junit.jupiter.api.Test;
  19.     import org.junit.After;
  20.     import static org.junit.Assert.*;
  21.     ...

I am using the following Selenium webdriver code and I am getting an exception at the driver.wait(0) line. I am using the wait statement to wait for a popup window to be loaded and allow the test to execute.

Here is a copy of my stacktrace:

This error message...

  1. java.lang.IllegalMonitorStateException

...at the line driver.wait(0); implies that it isn't a valid line of code as per current Selenium Java bindings. Hence you see the error.

Solution

In case you are looking for a hardcoded wait, you need to replace the line with:

  1. Thread.sleep(3000); //program execution gets halted for 3 seconds

You can also induce ImplicitWait, then you need to replace the line with:

  1. driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10)); //forces the driver will poll the HTML DOM for 10 seconds.
