[英]JMETER Beanshell ( java.lang.String ) not found in class
I am developing a Jmeter beanshell script to work with Selenium. 我正在开发一个Jmeter beanshell脚本来使用Selenium。 I decided to use the beanshell sampler so i can use java and selenium commands not accessible in the WDS interface. 我决定使用beanshell采样器,因此我可以使用WDS界面中无法访问的java和selenium命令。
My code work fine except for some String inputs. 我的代码工作正常,除了一些String输入。 Here is a sample (torn down to barebones): 这是一个样本(拆除为准系统):
import org.openqa.selenium.chrome.ChromeOptions;
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
and i get this error 我得到这个错误
2017/03/31 13:43:21 ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``import org.openqa.selenium.chrome.ChromeOptions; debug(); ChromeOptions options . . . '' : Error in method invocation: Method addArguments( java.lang.String ) not found in class'org.openqa.selenium.chrome.ChromeOptions' 2017/03/31 13:43:21 WARN - jmeter.protocol.java.sampler.BeanShellSampler: org.apache.jorphan.util.JMeterException: Error invoking bsh method: eval Sourced file: inline evaluation of: ``import org.openqa.selenium.chrome.ChromeOptions; debug(); ChromeOptions options . . . '' : Error in method invocation: Method addArguments( java.lang.String ) not found in class'org.openqa.selenium.chrome.ChromeOptions' 201
I see this similar in some other commands like sendkeys. 我在sendkeys等其他命令中看到了这一点。
Why is this command not taking my String? 为什么这个命令不带我的字符串? I can run the full script and the browser opens file so i know selenium is setup with jmeter. 我可以运行完整的脚本,浏览器打开文件,所以我知道selenium是用jmeter设置的。 It is just certain commands that use Strings that do this. 只是某些命令使用字符串来执行此操作。
Thanks J 谢谢J
Depending on your Selenium client libraries version you may not have this method taking single String as a parameter. 根据您的Selenium客户端库版本,您可能没有此方法将单个String作为参数。 Create a new Beanshell Sampler with the following line: 使用以下行创建一个新的Beanshell Sampler :
log.info(javap(org.openqa.selenium.chrome.ChromeOptions));
And look into JMeter console: you will see javap command printing out all the available methods for the ChromeOptions class, for instance for my installation (I have WebDriver Sampler plugin) it outputs the following: 并查看JMeter控制台:您将看到javap命令打印出ChromeOptions类的所有可用方法,例如我的安装(我有WebDriver Sampler插件),它输出以下内容:
Class class org.openqa.selenium.chrome.ChromeOptions extends class java.lang.Object 类class org.openqa.selenium.chrome.ChromeOptions扩展了类java.lang.Object
public boolean org.openqa.selenium.chrome.ChromeOptions.equals(java.lang.Object) public boolean org.openqa.selenium.chrome.ChromeOptions.equals(java.lang.Object)
public int org.openqa.selenium.chrome.ChromeOptions.hashCode() public int org.openqa.selenium.chrome.ChromeOptions.hashCode()
public void org.openqa.selenium.chrome.ChromeOptions. public void org.openqa.selenium.chrome.ChromeOptions。 addArguments(java.lang.String[]) addArguments(java.lang.String中[])
public void org.openqa.selenium.chrome.ChromeOptions. public void org.openqa.selenium.chrome.ChromeOptions。 addArguments(java.util.List) addArguments(java.util.List中)
If you use the same Selenium libraries version (2.52.0) as I do you should change this line: 如果你像我一样使用相同的Selenium库版本(2.52.0),你应该改变这一行:
options.addArguments("start-maximized");
to this one: 到这一个:
options.addArguments(new String[] {"start-maximized"});
And your script should start working as expected. 并且您的脚本应该按预期开始工作。
