What?JMeter做UI自动化!

1|0JMeter做UI自动化

不推荐，好别扭，但可行

2|0插件安装

• 搜插件selenium，安装

3|0添加config

• 添加线程组
• 右键线程组->添加->配置元件->jp@gc - Chrome Driver Config

• option和proxy不解释了

4|0添加Sampler

• 右键线程组->添加->取样器->jp@gc - WebDriver Sampler

• script language 选择：JavaScript（可惜没有python）

• 界面说明

  • Name - for the test that each Web Driver Sampler will have. This is used by the reports.
  • Parameters - is optional and allows the reader to inject variables used in the script section.
  • Script - allows the scripter to control the Web Driver and capture times and success/failure outcomes

5|0DEMO代码及解释

https://jmeter-plugins.org/wiki/WebDriverSampler/

• 示例代码

// 相当于python的from  import   java的import
var pkg = JavaImporter(org.openqa.selenium)
 
// Start capturing the sampler timing 开始捕获取样
WDS.sampleResult.sampleStart()

// 代码块
WDS.browser.get('http://114.116.2.138:8090/forum.php')
WDS.browser.findElement(pkg.By.id('ls_username')).sendKeys('admin')
// 等价于 WDS.browser.findElement(org.openqa.selenium.By.id('ls_username')).sendKeys('admin')
WDS.browser.findElement(pkg.By.id('ls_password')).sendKeys('123456')
// js语法定义了一个 sleep函数 ，让你从python平滑过渡到 js
var sleep = function(time) {
    var timeOut = new Date().getTime() + parseInt(time, 10);
    while(new Date().getTime() <= timeOut) {}
}

WDS.browser.findElement(pkg.By.cssSelector('.pn.vm')).click()
sleep(3000)

// 断言部分
if(WDS.browser.getCurrentUrl() != 'http://114.116.2.138:8090/forum.php') {
    WDS.sampleResult.setSuccessful(false)
    WDS.sampleResult.setResponseMessage('Expected url to be XXX')
}
else{
	WDS.sampleResult.setSuccessful(true)
}

// Stop the sampler timing 停止取样
WDS.sampleResult.sampleEnd()

• WDS就是Web Driver Sampler

• 麻烦的是你可能并没有自动补齐(好像可以出来，但没研究)，这个对象有哪些属性方法

• 深入的研究要看

  https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/package-summary.html
  

• 比如显式等待的一个应用

  var pkg = JavaImporter(org.openqa.selenium, org.openqa.selenium.support.ui)
  var wait = new pkg.WebDriverWait(WDS.browser, 5, 0.5)
  wait.until(pkg.ExpectedConditions.presenceOfElementLocated(pkg.By.cssSelector('ul.suggestions')))
  

5|1关于WDS的一些属性

1. WDS.name - is the value provided in the Name field (above).
2. WDS.vars - JMeterVariables - e.g.

vars.get("VAR1"); vars.put("VAR2","value"); vars.remove("VAR3"); vars.putObject("OBJ1",new Object());

1. WDS.props - JMeterProperties (class java.util.Properties) - e.g.

props.get("START.HMS"); props.put("PROP1","1234");

1. WDS.ctx - JMeterContext
2. WDS.parameters - is the value provided in the Parameters field (above).
3. WDS.args - is an array of the strings provided in the Parameters field, but split by the space ' ' character. This allows the scripter to provide a number of strings as input and access each one by position.
4. WDS.log - is a Logger instance to allow the scripter to debug their scripts by writing information to the jmeter log file (JMeter provides a GUI for its log entries)
5. WDS.browser - is the configured Web Driver browser that the scripter can script and control. There is detailed documentation on this object on the Selenium Javadocs page.
6. WDS.sampleResult - is used to log when the timing should start and end. Furthermore, the scripter can set success/failure state on this object, and this SampleResult is then used by the JMeter reporting suite. The JMeter javadocs provide more information on the API of this object
