使用Docker运行Jmeter Webdriver测试会给我CannotResolveClassException

标签： docker jmeter webdriver selenium-chromedriver jmeter-plugins

我使用可在我的本地计算机上运行的JMeter和Webdriver插件进行了一项测试，但是在针对Docker容器运行时，该测试无法正常工作。

首先，我使用Jenkins运行作业，对于每个JMeter作业，我需要使用测试的所有用户数据创建csv文件，我在Java 11中创建了一个CLI应用程序来实现这一目的。然后，我在同一容器内的CLI模式下运行jmeter。

这是我使用的dockerfile，来自“ selenium / standalone-chrome-debug”，因此我在容器中有google-chrome-stable和chromedriver二进制文件：

FROM selenium/standalone-chrome-debug:latest

这是jmx文件，“ jp @ gc-WebDriver Sampler”部分（使用Java代码）：

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

WDS.sampleResult.sampleStart();

String baseUrl = WDS.vars.get("hostname");

WDS.browser.get(baseUrl + "/");

WebDriverWait wait = new WebDriverWait(WDS.browser, 10);
wait.until(ExpectedConditions.elementToBeClickable(WDS.browser.findElement(By.id("username"))));
wait.until(ExpectedConditions.elementToBeClickable(WDS.browser.findElement(By.id("password"))));
wait.until(ExpectedConditions.elementToBeClickable(WDS.browser.findElement(By.id("enterButton"))));

WDS.sampleResult.sampleEnd();

这是ChromeDriver的配置部分：

<com.googlecode.jmeter.plugins.webdriver.config.ChromeDriverConfig guiclass="com.googlecode.jmeter.plugins.webdriver.config.gui.ChromeDriverConfigGui" testclass="com.googlecode.jmeter.plugins.webdriver.config.ChromeDriverConfig" testname="jp@gc - Chrome Driver Config" enabled="true">

        <boolProp name="ChromeDriverConfig.insecurecerts_enabled">false</boolProp>
      </com.googlecode.jmeter.plugins.webdriver.config.ChromeDriverConfig>

然后使用以下命令构建映像并运行jmeter测试：

$ docker build -t docker/chromejmeter -f docker/DockerfileChromeDebugJmeter docker/

$ docker run --env 'JVM_ARGS=-Xms2048m -Xmx2048m -XX:NewSize=2048m -XX:MaxNewSize=2048m' -v `pwd`:`pwd` -w `pwd` --name TestWebChromeJmeter docker/chromejmeter jmeter -n -Jdatasource_file=user_data.csv -t src/test/jmeter/testPlans/plans/Web_Login_UserLogin_Test.jmx -l src/test/jmeter/reports/Web_Login_UserLogin_Test.jtl

但是我收到以下错误消息：

Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/home/lea/repos/automation/src/test/jmeter/testPlans/plans/WebWebclient_Login_UserLogin_Test.jmx'.
Cause:

如果我在没有docker的情况下运行相同的测试，则工作正常：

我对上述文件进行了一些更改，并且效果很好。希望它对您有帮助

COPY launch.sh /

WORKDIR ${JMETER_HOME}

ENTRYPOINT ["/launch.sh"]

launch.sh具有以下代码

#!/bin/bash

set -e
freeMem=`awk '/MemFree/ { print int($2/1024) }' /proc/meminfo`
s=$(($freeMem/10*8))
x=$(($freeMem/10*8))
n=$(($freeMem/10*2))
export JVM_ARGS="-Xmn${n}m -Xms${s}m -Xmx${x}m"

echo "JVM_ARGS=${JVM_ARGS}"
echo "jmeter args=$@"

jmeter $@

对于chromedriver配置，请确保您添加了正确的驱动程序路径

现在是您面临的问题的答案。这就是您调用jmeter容器的方式。 

export volume_path="<give the path to the folder  where you have your jmx file>" && export jmeter_path="<give the path within your container>" && docker run --name jmeter_${NOW} --volume "${volume_path}":${jmeter_path} jmeterdocker   -n    -t ${jmeter_path}/<name of your jmx file>   -l tmp/result_${NOW}.jtl   -j tmp/jmeter_${NOW}.log

以上命令将volume_path下的所有文件复制到容器内的jmeter_path。现在，已经创建了.jtl和.log文件，并将其保存在jmeter bin文件夹下，因为根据launch.sh

，容器当前位于该路径下。

现在要从容器中获取日志文件，您以后可以使用docker cp命令。
