i have number which is in encrypted form and I have to pass this encrypted value to the API from Jmeter. I know I can use Random Variable in Jmeter to generate random values. But how to generate random encrypted value?
PS: I am new to Jmeter.
It depends on the encryption algorithm, for example you have __MD5() and __base64Encode() functions available via JMeter Plugins.
You can install these custom functions using JMeter Plugins Manager
For other encryption algorithms you can use JSR223 PreProcessor and Groovy language to write the encryption code.
This encrypted value can be either session id or authentication token.
You need to extract these values from request which is generating your random encrypted value and add it as header in required request.
Hope this helps you...

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})}
I'm using jmeter 5.0 to test my web application.How to encrypt the whole bodydata using AES before post ?
I've tried to do it with BeanShell PreProcessor,but it seems there is no method to reset the bodydata,what I found is how to print the bodydata.
log.info("test");
String bodydata = sampler.getArguments().toString();
log.info(bodydata);
I've aleardy known how to implement the AES funtion by importing a java calss.What I expect is resetting the bodydata of plaintext to encrypted text.
Put in body data just a JMeter variable as ${encryptData}
And in preprocessor set the variable with your encrypted value:
vars.put("encryptData", encryptData)
There is Arguments.removeAllArguments() function which clears the sampler body
You can add the new body via Arguments.addArgument() function. Example code:
sampler.getArguments().removeAllArguments();
sampler.addNonEncodedArgument("","your_encrypted_data_here","");
sampler.setPostBodyRaw(true);
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting mainly due to the fact that Groovy has much better performance comparing to Beanshell. So consider migrating to JSR223 PreProcessor on next available opportunity, the same code should work fine.
Under your "HTTP Request" add an "User Defined Variables" (empty values), Make sure as well to key in ${inputJson} in the "Parameters" text field in the "BeanShell PreProcessor" Element.
Very new to JMeter (and a long time Stack Overflow listener but first time caller so take it easy on me) so any help would be appreciated.
I am trying to set up a JMeter test that uses multiple dynamically generated access tokens to run across scenarios. I currently have a set of data using the CSV Data Set Config containing login credentials of a user's email and password for example:
email1#email.com,password1
email2#email.com,password2
Next I send a HTTP POST request to the Login service which generates an accessToken. Then, I am using the JSON Extractor to grab the generated accessToken. After that I am using the BeanShell Assertion to store the accessToken property/variable.
My issue seems to lie here in this last step since it will only store the last generated variable instead of each of the generated accessTokens. I want to be able to store/overwrite the grabbed accessToken for each email password combination. I would like it to modify/populate the CSV file like this:
email1#email.com,password1,accessToken1
email2#email.com,password2,accessToken2
I have also tried using the Pre Processor > User Parameters
Screen shot of User Parameters
I would like to have the "userBearerToken" variable update/overwrite along with the tests, but I cannot find a way to do so or if this can even currently be done.
I'm finding it difficult to word what I am trying to ask, but basically I want to store multiple dynamically generated variables (accessTokens that change and time out) and use them in other tests. I don't care which component can handle this (either the CSV or User Parameter), but I need to be able to store these variables with their corresponding email password credentials.
If you want to store the accessToken value into a JMeter property for using in other Thread Group(s) be aware that properties are global for the whole JVM and remain until JMeter is restarted so if you define a single accessToken property - each JMeter Thread (or iteration) will overwrite the value.
The solution is to use current thread (or iteration) number as prefix or postfix, this can be done using either __${__threadNum} function or relevant JMeter Variable depending on how iteration is defined or both.
Example setup:
In first thread group: ${__setProperty(access_token_${__threadNum},bar,)}
In second thread group: ${__P(access_token_${__threadNum},)}
Demo:
If you want to save the values into a file writing into the current one is not the best idea as you can (and most probably will) get malformed file due to a form of a race condition. So I would recommend using Sample Variables property instead.
If you add the next line to user.properties file:
sample_variables=email,password,accessToken
JMeter will store the variables named ${email}, ${password}, and ${accessToken} along with their values in the .jtl results file which is basically CSV file which can be re-used anywhere else.
However if you have a requirement to store only the credentials and the token you can go for the Flexible File Writer plugin and configure it to save the aforementioned variables values into a separate file, the relevant configuration would be as simple as:
variable#0,variable#1,variable#2
You can install Flexible File Writer plugin using JMeter Plugins Manager
I am trying to apply load sample request is like
http://54.174.110.64:8080/adserver/html5/inwapads/?adFormat=preappvideo&ak=O4DCX2&version=1.0&adu=5&cb=1494853894218&output=vast&priority=1&size=[vdo_adSize]&pageURL=http://qa.vdopia.com/qa/Ruchi/ssp_preroll1.html?0.7888977&domain=vdopia.com&refURL=&category=[CATEGORY]&siteName=vdopia&displayManager=Vdopia-SPP-Web&di=[COOKIE_ID]&dif=fpcm&sex=[GENDER]&age=[AGE];ipAddress=203.122.9.130;di=abcdefghijklmn
I have single request, what I want is that same request should have unique di (last key in query param). Nothing else I want to change.
My test is based on unique di in request keeping other parameters constant.
You can use Random function.
Hint:
I would suggest using __UUID() function which will generate a GUID structure which is unique according to the underlying algorithm each time being called.
If you don't like dashes you can remove them via __groovy() function like
${__groovy("${__UUID}".replaceAll("-"\, ""),)}
Demo:
See Apache JMeter Functions - An Introduction to get started with JMeter Functions.
I have used below approach :
ad di=${di_random}in path of HTTP request
I'd like to test a restful web service which requires a custom authentication scheme (MD5 of the URL with a recent timestamp).
e.g. URL http://test.com/secret/stuff/csv_val?uid=123&ts=1388695589&sig=e8dcf859a079e8670a5765e3eb0413e4
Where csv_val is a dynamic value coming from a CSV file, uid is my user ID, ts is the current timestamp and sig is the MD5 of MY_SECRET_KEYhttp://test.com/secret/stuff/csv_val?uid=123&ts=1388695589
From my research I think I should be using a JSR223 pre-processor to generate the timestamp and MD5 but it is not clear how I can get access to the full URL inside the script. I found an SO post (How to connect Jmeter to Java class?) which looked very promising but doesn't seem to work for me.
So my question is: how can I get access to the HTTP request parameters (host, port, path, protocol, etc...) inside a pre-processor?
You can use user defined variables to store needed values. After that you construct your request the next way:
where values in ${...} are user defined variables. Values for them can be created in BeanShell, BSF or RS2323 preprocessor. Here is some API to work with UDV. Here is pretty similar question jmeter var.putobject variable use in other jdbc request, but it is ignored. And here is a link so that you can read csv_val from CSV file.
