I am doing API REST Performance testing. For each API call, I have to send a unique Transaction and request ID in headers.
I use ${__UUID()} in headers, and it's working fine.
To track the transaction id in server logs, I want to print that function( ${__UUID()}) generated value in a log file with API name. For that, I have tried many ways, but those are very complicated and messy. Without adding a preprocessor can we log the value of the transaction id value from the request header?
I would be grateful if you throw some light on this.
I didn't understand why you don't want top use a preprocessor. I think it would be the best solution to generate the uuid in a script and store value before each request execution:
import java.util.UUID;
String uuid = UUID.randomUUID().toString();
log.info("Next uuid "+uuid);
vars.put("uuid",uuid);
Use the ${uuid} in your request header.
If you want to have the generated GUID printed in jmeter.log file - just wrap it into __log() function like:
${__log(${__UUID()})}
This will both generate the GUID and print the corresponding line into jmeter.log file:

When i perform the action on UI a dynamic refid is appended to the URL using query string parameter. I can't find that refid in the response but its part of the request. In the code i only found the variable.
Here is the URL on UI.
https://XXXXXX.XXXXXXXXXXXX.com/Recruiter/#!/candidate/new/157072048
I captured the Get request for the same action using the developer tool on Chrome and it looks like this.
Request URL: https://XXXXXX.XXXXXXXXXXXX.com/Pages/candidate/new.aspx?refid=157072048&mode=quick
This Get request has 2 query string parameter.
refid: 157072048
mode: quick
Now i need to captured that refid and pass it the step 2 to be able to create that record. I need help to figure this out.
I found comment in the html that may be help full.
// referenceid - only used with the "Web" app, gets mapped to "&refid=123" in the query string, and ends up as Page.ReferenceID in WebForms.
If this is not a part of a response data then it might be the case it's generated on the client by JavaScript code. You need to figure out how the value is being generated and replicate the same code using JSR223 Test Elements and Groovy language.
Another possibility is that the value comes from an Ajax request which JMeter doesn't execute because it cannot execute client-side JavaScript. In this case you need to simulate the same request and extract the value from there.
And last but not the least, the number you're looking for may reside in one of the sub-samples which may appear as the result of Redirection and you're trying to find it in main sampler response:
I'm trying to solve a test data issue in Jmeter. Can anyone of you have a look at below problem statement and advise here please ?
Requirement: Need to send all entries in a CSV file to HTTP request body in 'one' request to the end point.
Example CSV File:
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d"
HTTP Request Body:
["${data}"}]
When the data is substituted, I should be able to get below output.
[
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d"
]
Problem Statement: When I use CSV data set config. file, I'm unable to concatenate all entries into one single request body. My understanding is, CSV data set config. the file is not the right option here.
Did some search in StackOverflow and followed a method to achieve above using JSR223 PreProcessor' and the link is, How to send multiple json body using jmeter?.
Followed the above link and tried added below custom code provided.
def builder = new StringBuilder()
new File('/path/to/plans.csv').readLines().each { line ->
builder.append(new File(line).text).append(System.getProperty('line.separator'))
}
sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument('', builder.toString(), '')
sampler.setPostBodyRaw(true)
Upon running, I get below error message,
Caused by: java.io.FileNotFoundException,
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d" (The filename, directory name, or volume label syntax is incorrect)
If the file is not found, then how come the entries are read and displayed in the log viewer?
Also, how do I link the output of custom code to the request body? Or is it taken care of by the custom code itself?
You have an error in your code, change this line:
builder.append(new File(line).text).append(System.getProperty('line.separator'))
to this one:
builder.append(line).append(System.getProperty('line.separator'))
If you want to send the full contents of the file you don't even need to go for scripting, you can use __FileToString() function right in the "Body data" tab of the HTTP Request sampler:
${__FileToString(/path/to/plans.csv,,)}
And last but not the least if you need to generate JSON from the plain text it might be a better idea to go for JsonBuilder class, see Apache Groovy - Why and How You Should Use It and Apache Groovy - Parsing and producing JSON
Two steps:
Add a User Parameter Pre-processor before the HTTP request:
Name: DATA
User_1: ${__FileToString(/path/to/plans.csv,,)}
Add the following to request body:
${DATA}
How to parameterize request if I am getting something similar to the following for login POST request in body data tab.
"{\"msg\":\"method\",\"method\":\"login\",\"params\":[{\"user\":{\"username\":\"testuser\"},\"password\":{\"digest\":\"5811c74a581ffdb892ab9eddfb9cf2d21772a98332a59de6aa26989e01f84057\",\"algorithm\":\"sha-256\"}}],\"id\":\"7\"}"]
It's generally easy to correlate when we are getting in Parameters TAB, but in cases how we can proceed? For all further requests - it's the similar case.
I tried to switch to Parameters TAB, but it says that it can not be converted to that format.
So How we can proceed?
The same way, just substitute hard-coded (recorded) values with the relevant JMeter Variables directly in the request body like:
"{\"msg\":\"method\",\"method\":\"login\",\"params\":[{\"user\":{\"username\":\"${username}\"},\"password\":{\"digest\":\"${password}\",\"algorithm\":\"sha-256\"}}],\"id\":\"${id}\"}"]
The most commonly used for parameterization test element is CSV Data Set Config, however other options exist.
URL format is
www.something.com/something/api/{uuid}?code=gomundw0gjq2kbvc3g63whfr9usap5rurjaq5vui5vm6xbt9hhqa8hbcpto4yatwpn26v42t9
I need to make several calls to this GET Url and check performance of the feature.
uuid here is not just the UUID , but is specific to my application
UUID= accountid+identifierid+uuid, which will look like 1234+1234+123e4567e89b12d3a456426655440000
How should I arrange my Jmeter Test Plan.
My Plan would be:
write UUID generated to a file
Using any preprocessor call the file from file and write program to append to a different value in the csv which is account/identifierid.
Please help on this, can some one explain how I should logically arrange my test plan and code to get data to parameterize my path in HTTP Request sampler.
Thanks in Advance
You need to get accountid+identifierid information stored into CSV file. This is something you need to do on your own.
You can use CSV Data Set Config in order to get the information from that file while your test is running, example configuration would be:
UUID can be generated using __UUID() function
So your HTTP Request sampler configuration would be something like:
I would like to read the exact value of a variable I use to pass through an HTTP Request. I first read in many values of variables using the CSV Data Set Config. For the username, it is in the form of an email address. So, I have a variable called "email" in the Data Set Config. In the actual HTTP Request, for "name", I call it "username". For the "Value" field for this same "username", I added a time() function to it like this so I would end up creating unique users in my tests:
${email}${__time()
When I view the "Request" in a View Results Tree, I can see my parameter is listed correctly:
username=email1%40email.com1390854377360
I do not care if this is correct in real world terms. I already know that is not a valid email. That is ok for now.
What I want to know is how can I log that email that I just created on the fly? I would like to not have to pull in the whole request every time also and then use some type of Regular Expression extractor. It just seems like there should be an easy way to do this.
I think there are 2 ways,
Beanshell Pre/Post processors : you can write custom code in which you can log all your variables in some custom log file
Simple data writer : you can configure it and check save url,save field names,save response data field checkboxes that will give you complete data but in that later postprocessing on result file is required to get all usernames (email in your case).
first approach is easier and allows you create your own logging format(easy to retrieve and use somewhere else).
second approach is somewhat tedious and requires post processing.
