Removing slash in Jmeter and passing the value to next api - jmeter

From csv confi i am passing a variable for encryption Api
that is "analytical_url":"api\/apply_weekoff"
i need to replace \/ with empty from "api/apply_weekoff" on passing to encryption api
any suggestion

If you have this value stored in a JMeter Variable you can use __groovy() function like:
${__groovy(vars.get('foo').replace('\\\\'\, ''),)}
The above code line assumes that you have foo JMeter Variable with the value of "analytical_url":"api\/apply_weekoff"
Alternatively you can use __strReplace() function like:
${__strReplace(${foo},\\\\,,)}
__strReplace() function is not present in default JMeter distribution bundle you will need to install it additionally using JMeter Plugins Manager

Assigning value to the variable based on the request

I have created a jmeter script as below
I am using the user defined variable with function __P() and passing the Url from .sh file
My requirement is, if the url passed is "www.abc.com" then set the value of the variable ${Prefix} to "foo" else set it to "bar"
I tried using JSR223 PostProcessor, but JSR223 PostProcessor has to have a sample associated with it.
Any suggestion how do I achieve it?
Use the following __groovy() function in the HTTP Request sampler directly:
${__groovy(if (vars.get('Url') == 'www.abc.com') {return 'foo'} else {return 'bar'},Prefix)}
For subsequent requests (once the __groovy() function has been run) you will be able to use just ${Prefix}

If you're not too comfortable with Groovy scripting you can consider using __if() function, it's a part of Custom JMeter Functions bundle, can be installed usign JMeter Plugins Manager

How can i generate a coulmn value as a random value in a csv file while doing load test with Jmeter

I am using Jmeter for load testing. I am passing parameters of the body from a csv file for an api. But our application will not receive the duplicate value. So when i load test by multiple users, the request get failed.because i am passing same parameter value for all users.So i need to make some of the columns with an instant value(random). so that different users will get different values.
{
"clinic_name":"clicnic",
"first_name":"provider1",
"initial":"v",
"last_name":"doc",
"salutation":"salu",
"address_1":"testttadd1",
"address_2":"testtttadd2",
"city":"ckdy",
"state":"Arizona",
"zip":"12365",
"fax":"",
"email":[{"email_id":"dfdf#dzcz.in","type":"Work","note":null}],
"phone":[{"number":"1235974444","note":"","type":"Mobile","extension":""}]
}
here i have given the request body and i need different email for different users. How can i do this?Can anyone help me..Thanks in advance.
you can use __RandomString function for the value of email_id:
"${__RandomString(15, abcdefghijklmnopqrstuvwxyz)}#${__RandomString(10, abcdefghijklmnopqrstuvwxyz)}.in"
The easiest is using Faker library like:
Download Java Faker jar and drop it to JMeter Classpath
Restart JMeter to pick the .jar up
You can use the following __groovy() function directly in the HTTP Request sampler body:
${__groovy(new com.github.javafaker.Faker().internet().emailAddress())}
Alternatively you can put the above expression into your CSV file, however make sure to wrap the variable reference into __eval() function, for example if you had ${email} you will need to change it to ${__eval(${email})}

How do I use a JMeter Variable declared in an extractor in a User Defined Variable config

I have an http request that uses an extractor to set a JMeter variable (lets call it test) from the body. When I look at the debug controller I can see this works fine. Next I want to append something to the beginning of the variable so I add a user defined variable node and add a variable with the name new and I set the value to ${test}. However when I look in the debug response I see ${test} instead of the value.
I tried the same thing setting the value manually in 2 different UDV nodes and it works fine, so how do I append to a JMeter variable declared in an extractor?
As per JMeter Documentation:
The User Defined Variables element lets you define an initial set of variables, just as in the Test Plan.
Note that all the UDV elements in a test plan - no matter where they are - are processed at the start.
So the User Defined Variables element will be read only once and only when the Test Plan is started.
If you need to overwrite the current variable with a new value you can go for i.e. __groovy() function, the relevant syntax would be something like:
${__groovy(vars.put('foo'\, 'some_prefix_' + vars.get('foo')),)}
Demo:
vars is a shorthand for JMeterVariables class instance, it provides read-write access to all JMeter Variables in the current thread scope. Check out The Groovy Templates Cheat Sheet for JMeter to learn what else you can do with Groovy scripting in JMeter tests
UDVs can't be used in dynamic way because they are process once at the start of the test.
Don't use UDV, use JSR223 Sampler (or PostProcessor) with vars;
vars.put("new", "prefix"+ vars.get("test"))
Another option is to use Set Variables Action plugin

Jmeter - How to add "counter" inside other variable in http request parameters

I'm getting variables from Cassandra(DataBase) request so my vars from Cassandra can be from id_0 to id_19.
I'm running in while controller so for each one I need to increment the id number.
I used counter with this code: ${story_id_${counter}} ,
but it didn't work
From JMeter user manual,
Note that variables cannot currently be nested; i.e ${Var${N}} does
not work. The __V (variable) function (versions after 2.2) can be used
to do this: ${__V(Var${N})}. In earlier JMeter versions one can use
${__BeanShell(vars.get("Var${N}")}

How do I call a Custom Function in JMeter

I've created a custom function in JMeter that returns a n length string with random characters. Where should I define the function, and how do I call it?
As long as your function is in the jmeter classpath, you should be able to call it just like any standard function with ${...} syntax, as described here.
Do make sure your jar file containing your function is in lib/ext, or added to the jmeter classpath via search_path's input option
You can do this in a beanshell script or via a javascript call. See the manual on
functions and on the beanshell preprocessor.
