Question

我正在使用带有Javascript的Web驱动程序采样器作为实时浏览器模拟的脚本语言。在Chrome的情况下，一切正常。但是，在IE的情况下，Internet Explorer驱动程序配置无法正常工作。 IE浏览器单独启动，其他操作不会被触发。以下是我收到的日志。

取样器代码是：

var pkg = JavaImporter(org.openqa.selenium, org.openqa.selenium.support.ui, org.openqa.selenium.ie.InternetExplorerDriver)
var wait = new pkg.WebDriverWait(WDS.browser, 60)
var username = WDS.args[0]
var password = WDS.args[1]
WDS.log.info('username :' + username)
WDS.log.info('password :' + password)
//WDS.browser.manage().window().maximize()
java.lang.Thread.sleep(1000);
WDS.browser.get("http://gmail.com")
WDS.sampleResult.sampleStart()
WDS.sampleResult.setSampleLabel("Login Page")

while(true) {
    var currentState = WDS.browser.executeScript("return document.readyState;").toString().equals("complete")
    if(currentState) {
        WDS.log.info('Login Page - Document loaded...')
        break
    } else {
        WDS.log.info('Login Page - Document is still loading...')
    }
}

while(true) {
    var activeRequest = WDS.browser.executeScript("return window.$.active;").toString().equals("0")
    if(activeRequest) {
        WDS.log.info('Login Page - Loaded all request...')
        break
    } else {
        WDS.log.info('Login Page - Still loading request...')
    }
}

wait.until(pkg.ExpectedConditions.presenceOfElementLocated(pkg.By.id('loginDiv')))
WDS.browser.findElement(pkg.By.id('username')).sendKeys([username])
WDS.browser.findElement(pkg.By.id('password')).sendKeys([password])
WDS.sampleResult.sampleEnd()
java.lang.Thread.sleep(10000);

以下是我到目前为止所做的事情：

在所有级别设置相同的安全模式 - 启用保护模式和所有级别的安全性都设置为“高”。
设置安全模式 - 在所有级别中禁用保护模式
在64位驱动程序的注册表中创建了DWORD - 没有启动浏览器本身。
尝试使用32位驱动程序 - 然后启动浏览器抛出异常。

请建议我解决这个问题的解决方案。

Answer 1

我已经执行了提供的脚本，直到获得gmail并成功执行。

从导入
检查Internet Explorer驱动程序的路径
评论完整代码，除了获取并尝试成功，然后进一步检查。
检查IE缩放级别为100％

我的系统规格： - IE-11 Windows 7（64位）

我对这种行为没有确切的解释，因为我对jmeter + selenium的工作量较少。

Answer 2

我使用以下步骤使其工作：

在JMeter 4.0中，安装Web驱动程序采样器时，与selenium相关 jar将在lib文件夹下自动下载。但是，版本是更老，即2.52.0。
因此，对于IE，请使用相同版本的IEDriver 32位或2.53.1 版本的32位IE驱动程序。没有其他版本可以使用。

我尝试更换最新的selenium jar，即3.9.1并更新了JMeter lib文件夹中的所有依赖jar，但是，得到以下异常：

如果有人发现解决方案是通过JMeter插件管理器更新最新的selenium版本，请在此处提供答案。

IE驱动程序无法使用Internet Explorer驱动程序配置在JMeter中使用Selenium
