I want to extract particular part of an url and manupulate it using BeanShell PreProcessor in Jmeter.
can anyone help me.
You can put a Regular Expression Extractor post-processor element as a child of the sampler from which you are going to extract the URL and in "Field to check" check the "URL". Here you can find more info about regular expression extractor and how to use it. And from here you can learn more about referencing functions and variables in JMeter.
This can be done in many ways .
regular expression extractor and select which part you want to extract and do the processor on it [in your case select the url] store it as a variable
add a post processor select language of your choice ,[plugin must be applied here]
i have done a sample here in groovy since groovy has a build in url library to access parts of the url
log.info vars.get("iurl")
input =vars.get("iurl")
URI ulrString = new URI(input[0])
vars.put("gHost",ulrString.getHost().toString())
vars.put("gPort",ulrString.getPort().toString())
vars.put("gPathUrl",ulrString.getPath().toString())
Hope this helps.
Depending on what part you need and what you can do with it approaches might differ, here is one of them:
In Beanshell PreProcessor you have sampler pre-defined variable which stands for parent Sampler instance. In case of HTTP Request it is HTTPSamplerProxy class. So you can use sampler.getUrl() method to get the whole URL, it will return java.net.URL instance so you will be able to use URL class methods to work with it like:
URL url = sampler.getUrl();
String protocol = url.getProtocol();
String host = url.getHost();
String path = url.getPath();
log.info("URL: " + url.toString());
log.info("Protocol: " + protocol);
log.info("Host: " + host);
log.info("Path: " + path);

I have to give dynamic values to url which takes number of users and their age , which can be selected though web page. but I want to give it in Jmeter using BeanShell PostProcessor.
Help me in this,since I'm new to Jmeter.
This is the path:
/destinations/packages?airports%5B%5D=LGW&units%5B%5D=000577%3ADESTINATION&when=29-05-2016&until=&flexibility=true&flexibleDays=3&noOfAdults=2&noOfSeniors=0&noOfChildren=1&childrenAge=3&duration=7114&first=0&searchType=search&searchRequestType=ins&sp=true&multiSelect=true
from what I've got looks like you can use CSV Data Set Config.
Create .txt file with the data you want to feed your test with;
Place the above .txt file to the folder where your .jmx file lies;
In your Test plan: Under your request sampler - place CSV Data set Config;
Then if you need to use your dynamic values within one threadgroup => refer these data as ${quanity}, ${age} in you url.
If you need to pass these values across the threadgroups => add BeanShell Assertion
Then (in the other Tread group) refer those as ${__property(_quantity)},${__property(_age)}.
Hope, it helps.
First of all you need Beanshell PreProcessor, not Beanshell PostProcessor.
All this parameters are basically name/value pairs which can be defined via HTTPSamplerBase class. HTTPSamplerBase class instance is available to Beanshell PreProcessor as sampler pre-defined variable so if you add the following code into the Beanshell PreProcessor "Script" area
sampler.addEncodedArgument("airports[]","LGW");
sampler.addEncodedArgument("units[]","000577:DESTINATION");
sampler.addEncodedArgument("when","29-05-2016");
sampler.addEncodedArgument("until","");
sampler.addEncodedArgument("flexibility", "true");
sampler.addEncodedArgument("flexibleDays","3");
sampler.addEncodedArgument("noOfAdults","2");
//etc
Your HTTP request will be populated with the values, you set via Beanshell.
JMeter Variables can be accessed via vars shorthand which stands for JMeterVariables class instance.
String airport = vars.get("airport");
sampler.addEncodedArgument("airports[]", airport);
//etc
See How to Use BeanShell: JMeter's Favorite Built-in Component article for comprehensive information on how to use Beanshell Test Elements in Jmeter.
Remember that it is recommended to avoid scripting where possible so if there is another way of implementing your task - go for it.
In jMeter How to get multi part body in BeanShell PreProcessor
I need to get the image data and post parameters
by using sampler.getArguments(); I am able to get the post parameters but not the image file
Please help me
You can use getHTTPFiles method of Sampler API.
sampler.getHTTPFiles() will return the file path HTTPFileArg in an array through which you can update new file at run time.
Update:
String path = sampler.getHTTPFiles()[0].getPath();
byte[] array = Files.readAllBytes(new File(path).toPath());
Something like:
File image = new File(sampler.getHTTPFiles()[0].getPath());
//do what you need with the image file
If you need extended image information take a look at ImageIO. For more Beanshell tips and tricks check out How to Use BeanShell: JMeter's Favorite Built-in Component
I am new to JMeter.
In my GET request I want to have random number of parameters, so sometimes I want to have:
a = value1
a = value2
a = value3
and sometimes I want to have
a = value1
a = value2
etc.
Can I achieve it in JMeter in another way than making separate request modules?
You can specify parameters dynamically in the Path field, using a variable:
The variable should be created / formatted before HTTP request is sent. For example here I am using counter and BeanShell pre-processor to create a proper set of parameters:
So if I run this with 3 iterations, I will get:
GET http://stackoverflow.com/x?a=value0
GET http://stackoverflow.com/x?a=value0&a=value1
GET http://stackoverflow.com/x?a=value0&a=value1&a=value2
etc. Of course the logic of creating params should be based on your needs, this is merely an example. The reusable part of that example is saving params in a string, and then saving them into variable:
String myDynamicParameters = "";
// your logic here
vars.put("myDynamicParameters", myDynamicParameters);
If you want to generate variable directly inside your GET parameters, the fastest way is to use inline snippets.
something like:
GET http://xx.com/${__Random(1,99999)}
You can do it via i.e. Beanshell PreProcessor like:
sampler.addArgument("name", "value");

I am reading the domain url from the CSVdatafile before hitting I need to replace the environment with some String
How I can achieve in Jmeter
data file entries
Tried following by adding the BeanShellPreprocesser
print("------Replcing the environment name------");
var str =new Stirng[]{${siteUrl}};
var res = str.replace("frep", ${env});
SampleResult.setResponseData(res);
still it is not working.
I need to read each entry from the Datafile and replace the "frep" with "abc" and then i need to hit the url
How I can achieve this in Jmeter?
According to your scenario Beanshell code should look like:
String siteUrl = vars.get("siteUrl");
siteUrl = siteUrl.replaceAll("frep", vars.get("env"));
vars.put("siteUrl", siteUrl);
Beanshell is more like Java, not JavaScript. You can use __javaScript() function to perform the substitution if you're more comfortable with it.

How Can i extract value from DWR call using RegEx in jmeter.
In My Script Request Body is something like :
POST data:
`callCount=1`
`page=/abc/xyz.action`
`httpSessionId=`
`scriptSessionId=87F34A5261EFBF481F6D421920EF99F9406`
`c0-scriptName=DWRPostHelper`
`c0-methodName=savePostAsDraft`
`c0-id=0`
`c0-param0=string:447`
`c0-param1=number:933`
`c0-param2=number:0`
`c0-param3=string:Post%20Jmeter`
`c0-param4=string:`
`c0-param5=string:1`
`c0-param6=number:1427199824585`
`batchId=4`
And Response data is as below :
`//#DWR-INSERT`
`//#DWR-REPLY`
`dwr.engine._remoteHandleCallback('4','0',["447","Auto-saved at 17:55"]);`
Need to Extract value 447 from above Response.
is it Possible Using RegEx ? or is there any other way to do the same?
'dwr\.engine\._remoteHandleCallback\('[0-9]','[0-9]',\["([0-9]+)",
This should do it, written from memory, you may need to tweak the syntax a bit. Use $1$ for the template.
Try the following:
dwr\.engine\._remoteHandleCallback\('4','0',\["(.+?)"
Make sure that you set $1$ as "Template"
You can test your regular expressions using View Results Tree listener as follows:
