Class StandardGenerator

All Implemented Interfaces:
Serializable, Generator

public class StandardGenerator extends Object implements Generator, Serializable

StandardGenerator will be the default generator used to pre-process logs. It uses JMeter classes to generate the .jmx file. The first version of the utility only generated the HTTP requests as XML, but it required users to copy and paste it into a blank jmx file. Doing that way isn't flexible and would require changes to keep the format in sync.

This version is a completely new class with a totally different implementation, since generating the XML is no longer handled by the generator. The generator is only responsible for handling the parsed results and passing it to the appropriate JMeter class.

the class needs to first create a thread group and add it to the HashTree. Then the samplers should be added to the thread group. Listeners shouldn't be added and should be left up to the user. One option is to provide parameters, so the user can pass the desired listener to the tool.

      close in interface Generator
    • setHost

      public void setHost(String host)
      The host is the name of the server.
      Specified by:
      setHost in interface Generator
      host - name of the server
    • setLabel

      public void setLabel(String label)
      This is the label for the request, which is used in the logs and results.
      Specified by:
      setLabel in interface Generator
      label - label of the request
    • setMethod

      public void setMethod(String post_get)
      The method is the HTTP request method. It's normally POST or GET.
      Specified by:
      setMethod in interface Generator
      post_get - method of the HTTP request
    • setParams

      public void setParams(NVPair[] params)
      Set the request parameters
      Specified by:
      setParams in interface Generator
      params - request parameter
    • setPath

      public void setPath(String path)
      The path is the web page you want to test.
      Specified by:
      setPath in interface Generator
      path - path of the web page
    • setPort

      public void setPort(int port)
      The default port for HTTP is 80, but not all servers run on that port.
      Specified by:
      setPort in interface Generator
      port - - port number
    • setQueryString

      public void setQueryString(String querystring)
      Set the querystring for the request if the method is GET.
      Specified by:
      setQueryString in interface Generator
      querystring - query string of the request
    • setSourceLogs

      public void setSourceLogs(String sourcefile)
      The source logs is the location where the access log resides.
      Specified by:
      setSourceLogs in interface Generator
      sourcefile - path to the access log file
    • setTarget

      public void setTarget(Object target)
      The target can be either a or a Sampler. We make it generic, so that later on we can use these classes directly from a HTTPSampler.
      Specified by:
      setTarget in interface Generator
      target - target to generate into
    • generateRequest

      public Object generateRequest()
      The method is responsible for calling the necessary methods to generate a valid request. If the generator is used to pre-process access logs, the method wouldn't return anything. If the generator is used by a control element, it should return the correct Sampler class with the required fields set.
      Specified by:
      generateRequest in interface Generator
      prefilled sampler
    • save

      public void save()
      save must be called to write the jmx file, otherwise it will not be saved.
      Specified by:
      save in interface Generator
    • reset

      public void reset()
      Reset the HTTPSampler to make sure it is a new instance.

      The purpose of the reset is so Samplers can explicitly call reset to create a new instance of HTTPSampler.

      Specified by:
      reset in interface Generator
