JMeter how to NOT fail 500 Internal Server Errors

Question

I am using JMeter as a unit test tool, in parameterised calls where I expect some of the responses to be 500 internal server errors. I am using BeanShell Assertions to chec

Answer 1

Using a BeanShell assertion, force the HTTP Sampler to pass and then pass/fail on a regular Beanshell assertion statement instead:

if (ResponseCode.equals("500") == true) { 
    SampleResult.setResponseOK();  

    /* the same is 
    SampleResult.setSuccessful(true);
    SampleResult.setResponseCodeOK();
    SampleResult.setResponseMessageOK();
    */
}
String path = SampleResult.getURL().getPath();
if (!path.contains("anerror")) {
    Failure = true;
    FailureMessage = "URL Path: didn't contain \"anerror\"" +
        System.getProperty("line.separator") + "URL Path detected: " + path;
}
