how to generate Jmeter CSV report just with defined regular expression variables - jmeter

Is it possible to get a CSV file report in JMeter just with only defined regular expression variables values from all the samplers?
Because I have defined sample_variables in JMeter user.properties file. Thanks.

The easiest way is using Flexible File Writer
A little bit harder - suppress all JMeter default result saving configuration via user.properties file like:
jmeter.save.saveservice.output_format=csv
jmeter.save.saveservice.assertion_results_failure_message=false
jmeter.save.saveservice.assertion_results=none
jmeter.save.saveservice.data_type=false
jmeter.save.saveservice.label=false
jmeter.save.saveservice.response_code=false
jmeter.save.saveservice.response_data=false
jmeter.save.saveservice.response_data.on_error=false
jmeter.save.saveservice.response_message=false
jmeter.save.saveservice.successful=false
jmeter.save.saveservice.thread_name=false
jmeter.save.saveservice.time=false
jmeter.save.saveservice.subresults=false
jmeter.save.saveservice.assertions=false
jmeter.save.saveservice.latency=false
jmeter.save.saveservice.connect_time=false
jmeter.save.saveservice.samplerData=false
jmeter.save.saveservice.responseHeaders=false
jmeter.save.saveservice.requestHeaders=false
jmeter.save.saveservice.encoding=false
jmeter.save.saveservice.bytes=false
jmeter.save.saveservice.url=false
jmeter.save.saveservice.filename=false
jmeter.save.saveservice.hostname=false
jmeter.save.saveservice.thread_counts=false
jmeter.save.saveservice.sample_count=false
jmeter.save.saveservice.idle_time=false
jmeter.save.saveservice.print_field_names=false
Hardest: add i.e. Beanshell Listener to write variable value to a separate file. Example code is something like:
import org.apache.commons.io.FileUtils;
FileUtils.writeStringToFile(new File("target_file.csv",vars.get("your_variable_name")));

How to replace a string in a variable that came from a CSV Data Config?

In my JMeter test plan, I have two CSV Data Config elements.
CSV Data Config-element-requestBodies: This CSV Data Config element has a variable named "requestBody". In the corresponding CSV file, each line has an XML request with a placeholder string.
CSV Data Config-element-subject: variables. This CSV Data Config element has a variable name "subjectDn". In the corresponding CSV file, each line has a distinguished name (DN) for a user.
The "requestBody" variable will contain an XML request from the CSV file that has the request bodies, with a placeholder string and I want to replace that placeholder with the contents of the "subjectDn" variable, and then use the modified "requestBody" variable in the HTTP Request element.
In other words:
Replace the placeholder string in the ${requestBody} with the value in the ${subjectDn}, then
Use the modified ${requestBody} in the HTTP Request
How can I do that? What is the easiest/least overhead way of doing that?
I've tried using the "__evalVar" function (see https://am.net/lib/tools/NetworkManagement/apache-jmeter-2.8/printable_docs/usermanual/functions.html), but it looks like that is not able to do the replacement when the string is from a CSV file?
Thanks in advance!
Jim
Wrap your ${requestBody} into __eval() function, it will allow JMeter to resolve JMeter Functions and Variables which are present as "placeholders" in the CSV file to their respective values.
${__eval(${requestBody})}
Also if you consider scripting to accomplish your requirements be informed that starting from JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language. More information: Apache Groovy: What Is Groovy Used For?
I was able to get this woring by using a Beanshell pre-processor and some Java code that does var.get() and then Java String replaceall() and then var.put().

Jmeter how to read file path within csv file

Is it possible to pass in file path or read from another file within csv? My test setup is something like that.
Jmeter Test
Http request -> body data -> "items": "${__property(${items})}",
CSV data config
Id,Name,Items
1,MyName,\input\items_json.txt
I want to include a file in csv items column and in jmeter test, it will read and post items json.
Got it working with this.
"items": ${__FileToString(${__property(${Items})},,)},
Not really, being a Configuration Element CSV Date Set Config is initialised before anything else so you will have to consider another approach, i.e.:
__CSVRead() function
__StringFromFile() function
__FileToString() function()
Functions are being evaluated exactly where they're called so this way you can use them for parameterization. See Apache JMeter Functions - An Introduction to learn more about JMeter Functions concept

how can i pass dynamic values to url in jmeter

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.

How to Print variable in aggregate report jmeter?

I want to pass variable to aggregate report to distinguish request .How to print/pass a variable in aggregate report jmeter?
Option 1: you can add variable to Sampler Name so you will be able to figure out the variable value and distinguish samplers basing on their labels in the Aggregate Report as
Option 2: you can use sample_variables JMeter property. JMeter will append variable values to sampler metrics in results .jtl file. It will not be displayed in the Aggregare Report, but it will be possible to analyze .jtl file with Excel or equivalent.
To use "sample_variables" feature add the following line to user.properties file (it is located under /bin folder of your JMeter installation)
sample_variables=VAR1,VAR2,VAR3
You can "tell" JMeter to store single or multiple variable values along with request metrics.
JMeter restart is required to pick up amended property from the "user.properties" file. Alternative way is providing property via -J command-line argument as
jmeter -Jsample_variables=foo -n -t /path/to/testplan.jmx
See Apache JMeter Properties Customization Guide for advanced information on using, setting and overriding JMeter properties.

jmeter : how to save parameter from response to external file and use it to enter another page?

How can i Save parameter or any word from the response of the page to external file (txt ot csv)ang get this parameter from the file to enter another page ?
In fact I want to be able to change the parameter dynamically via file.
Thanks.
To save the whole response thing into a file:
Add a Beanshell PostProcessor as a child of the sampler, whose data you need to save.
Add the following code to the PostProcessor's "Script" area
import org.apache.commons.io.FileUtils;
File file = new File("/path/to/your/file.txt");
FileUtils.writeByteArrayToFile(file, data);
To read file contents in JMeter:
Just use __FileToString function wherever file's content is required as:
${__FileToString(/path/to/your/file.txt,,)}
For more information on Beanshell bit refer to How to use BeanShell: JMeter's favorite built-in component guide.
For high loads it will be better to replace Beanshell PostProcessor with JSR223 PostProcessor and choose "groovy" as the language (you'll need groovy-all.jar somewhere in JMeter's classpath)
