Question

So right now I have my http request under a while controller and I have a user defined variable Failure set to true. I would like jmeter to keep trying this request until it succeeded (without returned 500). My while loop condition is:

${__javaScript(${Failure})}

I also tried ${Failure} as while condition but getting the same result.

And I have a JSR223 Assertion after the result tree as following:

if (ResponseCode.equals("500") == true) {
    vars.put("Failure", true)
}
else { 
    vars.put("Failure", false)
}

When I ran this, I got into infinite loop even my request succeeded. It seems the Failure value was never updated. Any suggestion on this would be appreciated.

Answer 1

这是因为您试图将Boolean对象添加到需要String的函数中。为了能够将布尔值存储到JMeter变量中，您需要使用vars.putObject()函数，例如：

vars.putObject("Failure", true)

或用引号将true括起来，这样对于Groovy来说它看起来像是一个字符串：

vars.put("Failure", "true");

修改您的JSR223断言代码，使其看起来像：

if (ResponseCode.equals("500")) {
    vars.put("Failure", "true")
}
else { 
    vars.put("Failure", "false")
}

将While控制器条件修改为${Failure}。如果需要执行一些脚本编写，则使用JavaScript是一种性能反模式的形式-请转到Groovy。在特定情况下，您可以仅使用${Failure}变量作为条件，因为它可以是true或false

我终于开始工作了。在我的JSR233断言中，我将其更新为：

if (prev.getResponseCode().equals("500")) {
    vars.put("Failure", "true")
}
else { 
    vars.put("Failure", "false")
}

它现在可以工作。
