Interface Generator
- StandardGenerator
public interface Generator
Description:
Generator is a base interface that defines the minimum methods needed to
implement a concrete generator. The reason for creating this interface is
eventually JMeter could use the logs directly rather than pre- process the
logs into a JMeter .jmx file. In situations where a test plan simulates load
from production logs, it is more efficient for JMeter to use the logs
directly.
From first hand experience, loading a test plan with 10K or more Requests
requires a lot of memory. It's important to keep in mind this type of testing
is closer to functional and regression testing than the typical stress tests.
Typically, this kind of testing is most useful for search sites that get a
large number of requests per day, but the request parameters vary
dramatically. E-commerce sites typically have limited inventory, therefore it
is better to design test plans that use data from the database.
void | close() - close the generator

Object | generateRequest() - The method is responsible for calling the necessary methods to generate a
valid request.

void | reset() - The purpose of the reset is so Samplers can explicitly call reset to
create a new instance of HTTPSampler.
|
void | save() - If the generator is converting the logs to a .jmx file, save should be
called.

void | setHost(String host) - The host is the name of the server.

void | setLabel(String label) - This is the label for the request, which is used in the logs and results.
|
void | setMethod(String post_get) - The method is the HTTP request method.
|
void | setParams(NVPair[] params) - Set the request parameters
|
void | setPath(String path) - The path is the web page you want to test.
|
void | setPort(int port) - The default port for HTTP is 80, but not all servers run on that port.
|
void | setQueryString(String querystring) - Set the querystring for the request if the method is GET.
|
void | setSourceLogs(String sourcefile) - The source logs is the location where the access log resides.

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.
reset
public void reset()
The purpose of the reset is so Samplers can explicitly call reset to
create a new instance of HTTPSampler.
save
public void save()
If the generator is converting the logs to a .jmx file, save should be
called.
setHost
public void setHost(String host)
The host is the 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.
setMethod
public void setMethod(String post_get)
The method is the HTTP request method. It's normally POST or GET.
setParams
public void setParams(NVPair[] params)
Set the request parameters
setPath
public void setPath(String path)
The path is the web page you want to test.
setPort
public void setPort(int port)
The default port for HTTP is 80, but not all servers run on that port.
setQueryString
public void setQueryString(String querystring)
Set the querystring for the request if the method is GET.
setSourceLogs
public void setSourceLogs(String sourcefile)
The source logs is the location where the access log resides.
setTarget
public void setTarget(Object target)
The target can be either a java.io.File or a Sampler. We make it generic,
so that later on we can use these classes directly from a HTTPSampler.
