I want to extract Response Title (HTML -> Head->Title) and want to add in CSV using beanshell. Can anyone please help in this. what code need to write in beanshell ?
If you need to store a JMeter Variable into a file the easiest option is using Sample Variables property.
add the next line to user.properties file (located in JMeter's "bin" folder)
sample_variables=yourVar
where yourVar should be your real "Reference Name" from the Regular Expression extractor
restart JMeter to pick up the change
when you run your test next time you will see an extra column in .jtl results file holding the required variable value
The property can be also set via -J command-line argument like:
jmeter -Jsample_variables=yourVar -n -t test.jmx -l result.jtl
If you still want to go for scripting be aware that recommended approach assumes JSR223 Test Elements and Groovy language. You can write a variable into a file in Groovy like:
new File('yourFile.csv') << vars.get('yourVar')
again replace yourVar with your real variable name.
If you still looking for Beanshell, the easiest way would be using FileUtils.writeStringToFile() function like
import org.apache.commons.io.FileUtils;
import java.nio.charset.StandardCharsets;
FileUtils.writeStringToFile(new File("yourFile.csv"), vars.get("yourVar"), StandardCharsets.UTF_8);

I am trying to generate a html report in JMeter. For which I am using below command:
jmeter -n -t C:\Controlled_Environment\apache-jmeter-5.4.1\bin\Automation\Cursor_Leak_Report.jmx -l C:\Controlled_Environment\apache-jmeter-5.4.1\bin\Automation\Curosr_Leak\cursor.csv -e -o C:\Controlled_Environment\apache-jmeter-5.4.1\bin\Automation\Curosr_Leak\cursor
But this html reports does not shows what values I have extracted.
For example, the .jmx helps to know how many Database connection are made to the App. I am extracting the count via SQL query and using regular expression extractor. How can I show in HTML dashboard the same.
By default it won't.
You need to:
Declare the variable you use in the Regular Expression Extractor as Sample Variable, i.e. add the next line to user.properties file (lives in "bin" folder of your JMeter installation)
sample_variables=foo
Configure HTML Reporting Dashboard to plot the custom chart over time providing this sample variable, it can be done in the same user.properties file:
jmeter.reportgenerator.graph.custom_testGraph.classname=org.apache.jmeter.report.processor.graph.impl.CustomGraphConsumer
jmeter.reportgenerator.graph.custom_testGraph.title=Variable from DB over Time
jmeter.reportgenerator.graph.custom_testGraph.property.set_Y_Axis=Variable from DB Value
jmeter.reportgenerator.graph.custom_testGraph.set_X_Axis=Over Time
jmeter.reportgenerator.graph.custom_testGraph.property.set_granularity=60000
jmeter.reportgenerator.graph.custom_testGraph.property.set_Sample_Variable_Name=foo
jmeter.reportgenerator.graph.custom_testGraph.property.set_Content_Message=Variable from DB :
I am fetching data from the CSV file and giving as input to my Request.How can I save all the request in the same file when I run a test for an hour.
One more requirement is, if the result is success then I have to write that data I have used from the CSV into another file so that we can have only the data which is working in an separate file.
Please suggest
The best way would be using JMeter's built-in Sample Variables property.
Add the next line to user.properties file:
sample_variables=foo
Replace foo with the variable name you're getting from the CSV file
Next time you run your JMeter test in command-line non-GUI mode like:
jmeter -n -t test.jmx -l result.csv
your result.csv file will have an extra column called foo and having the foo variable value for each and every request. You will be also able to determine which data caused the failure by looking into "success" column
How to save exact response from Jmeter in a file?
e.g. - I have a response as email only so I want to save this email address only in a file with a success and failure but If I am saving a file as xml its giving a whole bunch of code otherwise if I save it as a csv file it's giving all sort of infomation other than a email address. Pls help me to solve it.
If you need to save the whole response - Save Responses to a file listener is what you're looking for.
If you need to store a part of the response - first of all get the necessary part with i.e. Regular Expression Extractor. Once you have JMeter Variable holding required value i.e. email you can add the next line to user.properties file (lives under /bin folder of your JMeter installation)
sample_variables=email
and ${email} variable value will be stored along with other results.
NB
you need to restart JMeter to pick the property up
you can also pass it via -J command line argument like:
jmeter -Jsample_variables=email -n -t /path/to/testplan.jmx -l /path/to/results.jtl

I am new to jmeter,and in my company we are doing webservices testing using jmeter.My requirement is i am using csv data config file for web services testing and here i want to update each row of csv file with test results and i am using beanshell postprocessor,please help
Ex:
csv contains:
Test Case,Dates,Numbers,Results
Total test cases are 16 and i want to update as below for each test case
TC_001,9-03-2016,001,PASS
TC_002,9-03-2016,0002,FAIL
and so one...
Result = "FAIL";
Response = prev.Get....();
If(Response.Contains("Valid"));
Results="PASS";
f = new FileOutputStream("/tmp/oders.csv", true);
p = new PrintStream(f);
this.interpreter.setOut(p);
print(Results + "," + Result);
f.close();
P.Close();
import java.io.File;
import org.apache.jmeter.services.FileServer; //jmeter spelling corrected
import java.io.FileWriter;
import java.io.PrintWriter;
import java.util.Arrays;
import java.io.Writer;
File file = new File("csvFilePath");
FileWriter fstream = new FileWriter(file, true);
// true, will append the file if already exist
BufferedWriter out = new BufferedWriter(fstream);
out.write("Save your data which you want to save");
out.write("Save your data which you want to save");
out.close();
fstream.close();
It might not be the best idea as:
You may have problems with re-using this file
You may run into a situation when 2 or more threads will be concurrently writing to the file and it will result in data loss, file corruption or IO Exception
I would recommend adding your "Test Case", "Dates" and "Numbers" variables to JMeter's .jtl results file instead using Sample Variables property like:
Given you have 3 variables: TestCase, Date and Number
Add the following line to user.properties file (it is located under /bin folder of your JMeter installation)
sample_variables=TestCase,Date,Number
On next JMeter restart you will see "TestCase", "Date" and "Number" variable values appended to .jtl results file.
It is also possible to pass the setting as a command-line parameter like:
jmeter -Jsample_variables=TestCase,Date,Number -n -t /path/to/testplan.jmx -l /path/to/results.jtl

I would like to share my experience using BeanShell PostProcessor to write variables to a file.
I captured few responses from the server using "Regular Expression Extractor" and saved it to few variables Var1 & Var2 and when I wrote these variables to a file using "BeanShell PostProcessor", I have observed that it works fine when we run a test with single thread but with multi thread test, the data was being lost.
Say When I inject 100 transactions, I was able to see only 97 records in the output file.
So the best option is to set sample_variables in user.properties file so that you can get the variables out in your .jtl results file.
In my Jmeter test, I am able to use REGEX Extraction, After extraction I want to write the value of the REGEX variable into a file
I found a workaround as using beanshell as mentioned here https://stackoverflow.com/a/15159521/4556894
Is there any clean way of doing it, May be some inbuilt features, which I am not aware of
It is possible to write variable values into JMeter .jtl results file. There is a JMeter Property called sample_variables
Optional list of JMeter variable names whose values are to be saved in the result data files.
Use commas to separate the names.For example:
sample_variables=SESSION_ID,REFERENCE
So if you run JMeter in command-line non-GUI mode as follows:
jmeter -Jsample_variables=myVariable -n -t /path/to/your/testplan.jmx -l /path/to/testresults.jtl
You'll get the output like
timeStamp,elapsed,label,responseCode,responseMessage,threadName,dataType,success,bytes,grpThreads,allThreads,Latency,"myVariable"
1425978657207,368,HTTP Request,200,OK,Thread Group 1-1,text,true,1591,1,1,367,YOUR_VARIABLE_VALUE
In above example column names are given for reference, they are not included into csv results file by default. This behavior is controllable via jmeter.save.saveservice.print_field_names property, set it to "true" to get column names printed along with results data.
You can also set sample_variables property value in user.properties file which lives under /bin folder of your JMeter installation or uncomment it in jmeter.properties file (same location)
