Interface Generator

- All Known Implementing Classes:
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.

Method Detail
-
close
void close()
close the generator
-
setHost
void setHost(String host)
The host is the name of the server.- Parameters:
host
- name of the server
-
setLabel
void setLabel(String label)
This is the label for the request, which is used in the logs and results.- Parameters:
label
- label of the request
-
setMethod
void setMethod(String post_get)
The method is the HTTP request method. It's normally POST or GET.- Parameters:
post_get
- method of the HTTP request
-
setParams
void setParams(NVPair[] params)
Set the request parameters- Parameters:
params
- request parameter
-
setPath
void setPath(String path)
The path is the web page you want to test.- Parameters:
path
- path of the web page
-
setPort
void setPort(int port)
The default port for HTTP is 80, but not all servers run on that port.- Parameters:
port
- - port number
-
setQueryString
void setQueryString(String querystring)
Set the querystring for the request if the method is GET.- Parameters:
querystring
- query string of the request
-
setSourceLogs
void setSourceLogs(String sourcefile)
The source logs is the location where the access log resides.- Parameters:
sourcefile
- path to the access log file
-
setTarget
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.- Parameters:
target
- target to generate into
-
generateRequest
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.- Returns:
- prefilled sampler
-
save
void save()
If the generator is converting the logs to a .jmx file, save should be called.
-
reset
void reset()
The purpose of the reset is so Samplers can explicitly call reset to create a new instance of HTTPSampler.
