英文:
Java.IllegalMonitorStateException thrown because of Selenium webdriver code driver.wait(0)
问题
以下是代码的翻译部分：
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。
这是我的堆栈跟踪副本：
java.lang.IllegalMonitorStateException
在java.lang.Object.wait(Native Method)中
在Test.MounaTest.test(MounaTest.java:61)中
...
这是代码：
package Test;
// 由Selenium IDE生成
import org.junit.Before;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.After;
import static org.junit.Assert.*;
...
英文:
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...
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:
Thread.sleep(3000); //program execution gets halted for 3 seconds
You can also induce ImplicitWait, then you need to replace the line with:
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10)); //forces the driver will poll the HTML DOM for 10 seconds.
