JMeter中使用Selenium WebDriver时无法匹配Wait Condition构造函数

问题场景 #

在JMeter 5.5中使用Groovy编写Selenium WebDriver脚本，尝试两种WebDriverWait构造方式均触发兼容性报错，仅等待条件相关代码异常，所有插件已更新。

原脚本 #

import org.openqa.selenium.*;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

//var wait = new WebDriverWait(WDS.browser, 5000)
//var wait = new org.openqa.selenium.support.ui.WebDriverWait(WDS.browser,    Java.time.Duration.ofSeconds(60))
    WDS.sampleResult.sampleStart()
    WDS.browser.get(url)
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.id('idSIButton9')));
    var nextbtn=WDS.browser.findElement(By.id('idSIButton9'));
    nextbtn.click();

    WDS.sampleResult.sampleEnd()

解决方案 #

报错核心原因是Selenium 4.x版本后，WebDriverWait构造方法不再支持直接传入毫秒数字（Long类型），必须使用Duration对象。同时Groovy中引用Java类需遵循语法规范，修正后的脚本如下：

import org.openqa.selenium.*;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;

WDS.sampleResult.sampleStart()
// 正确初始化WebDriverWait，使用Duration对象定义等待时长
def wait = new WebDriverWait(WDS.browser, Duration.ofSeconds(60))
WDS.browser.get(url)
// 等待目标元素可见
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id('idSIButton9')))
// 直接定位并点击按钮，简化代码
WDS.browser.findElement(By.id('idSIButton9')).click()

WDS.sampleResult.sampleEnd()

关键修正点 #

• 导入java.time.Duration类，确保能正确创建符合要求的时长对象
• 使用Duration.ofSeconds(60)替代直接传数字，适配Selenium 4.x的API规范
• 删除重复的导入语句，精简代码结构
• 取消注释并正确初始化wait变量，避免未定义错误
