I have a requested in jmeter that request created new one request, so I need that new one request url in a variable because new one request having a user I'd.
You can handle this situation in at least 2 ways:
Extract the dynamic part using Regular Expression Extractor:
Add Regular Expression Extractor as a child of the 1st request
Configure it as follows:
Field to check: URL
Reference Name: anything meaningful, i.e. id
Regular Expression:userId=(.*)
Template: $1$
Assuming everything goes well you should be able to refer extracted value as ${id} where required (manually add it to the end of each and every request)
You can semi-automate the process using Using the HTTP URL Re-writing Modifier, just add it as a child of the first request and put userId into "Session Argument Name" input field, JMeter should be smart enough to automatically add these "userId" postfixes to subsequent requests.

I record my script from internet explorer using JMeter version 3.3 but when I run it the first HTTP request created a new session but the next request is nothing changed it is because the session id of the second request is indicated to its path unlike the first request.
So this is my question, How to use session id from the previous request and put it to the path in the second request. Please see the image below
Add Regular Expression Extractor as a child of the first request and configure it as follows:
Reference Name: anything meaningful, i.e. SessionId
Regular Expression: SessionId=([+-]?\d+)
Template: $1$
Replace hard-coded recorded value in 2nd request with ${SessionId}

Login page is having dynamic password field name: every time user visits the login page field name looks like PASSWORD_673834937, and on next visit, it looks like PASSWORD_673857943.
I have created many scripts which were working as of today, but in latest build they bring in this change to the password field... before this it was always PASSWORD only. So all my scripts were failing. What is the workaround, so that all my scripts start working with dynamic field name?
OLD JMETER SCRIPT using name as "PASSWORD"
NEW changes to the password field
Under register.asp sampler, add RegEx Post-Processor
Specify the following parameters:
(i.e. the regular expression is <input TYPE="password" NAME="([^"]+)")
In HTTP Request, in the row where password is provided, specify variable created by RegEx Post-Processor in Field name, instead of static name. For example, since the variable I created above is called PasswordFieldName, the HTTP Sampler should look like this (omitting irrelevant parameters):
This is a matter of missing correlation, you would need this sooner or later given you continue playing with JMeter.
The idea of bypassing dynamic parameters is building your Test Plan as follows:
Request 1 (open login page)
Extract dynamic parameters and store them into JMeter Variables
Request 2 (perform login) providing credentials and all dynamic variables from the previous step
Add CSS/JQuery Extractor (be aware that it is not recommended to use regular expressions to work with HTML data) as a child of the register.asp page and configure it as follows:
Reference Name: anything meaningful, i.e. name
CSS/JQuery Expression: input[title=Password]
Attribute: name
Replace PASSWORD_673834937 with ${name} in the new script.
I want to manipulate the request body of HTTP thread based on the data extracted (using 'Regular Expression Extractor') from the previous HTTP response.
Here is the scenario:-
I have extracted the statusFlag and statusId from 'HTTP request 1' as:
Ref name: status
Reg. Exp: "statusFlag":"(\w+)","statusId":"(\w+)"
So, first I want to check that the value of statusFlag is 'New' or not.
If it is New then I have to proceed and feed statusId in next HTTP request or else display statusFlag mismatch.
Need help. Got stuck badly.
I believe Response Assertion is what you're looking for. Add it after the Regular Expression Extractor and configure it as follows:
Apply to: JMeter Variable -> statusFlag (or your reference name)
Pattern Matching Rules: Equals
Add New as a "Pattern to Test"
The assertion will check whether "statusFlag" is "New" and if not - it will fail the sampler and report the expected and the actual value.
Optionally you can add If Controller after the Response Assertion, use ${JMeterThread.last_sample_ok} as a condition and place 2nd request as a child of the If Controller - it will be executed only if "statusFlag" is new.
See How to Use JMeter Assertions in Three Easy Steps guide for more information on conditionally setting pass or fail criteria to requests in your JMeter test.
That's how your Jmeter project should look like.
Regular Expression Extractor stores extracted value in ct variable that can be accessed in If Controller as "${ct}" == "yourvalue" and, if true, can be also sent as a part of Request 2 body using the same ${ct} reference.

Can somebody please explain me how can I use JMeter for Feature testing?
I'm able to create multiple HTTP requests within a Testplan. But I need know the way to capture the previous API response and pass one of the response data to the next API request.
Eg:
1.Create Account.
Request- POST: /account
Response: ID: "Value"
Read account
Request- GET: /account/
JMeter is really more of a load testing tool, and best used as such. Capturing data from responses is possible using the Regular Expression Extractor, which can store extracted values in variables for use in a subsequent request. It is a bit of a pain in the ass to use, though.
On your request, add a Regular Expression Extractor:
Field to check: body
Reference name: EXAMPLE
Regular Expression: \[.*\] #your regex here, stuff in square brackets as example
Match No.: 1
In a subsequent request, you can then use the variables defined by the extractor, e.g. ${EXAMPLE_g0} for the entire match, or ${EXAMPLE_g1} for group 1, etc.
I use JMeter to do performance test of web server. My test case is as following:
step1: send file update request to server.
step2: server will return some files URL as html response
step3: client need to create new request with the URL returned in step2,thus need to parse
the response of step2.
I am new to JMeter, and do not know how to implement it. I basically learned JMeter about the pre-processor and post-processor, but still no clue about how to do.
Ok let's start before the first step :
Right click -> Add -> Threads (Users) -> Thread Group
Now the actual first step (If you use REST) :
Add -> Sampler -> Http Request
You have at the bottom part Send Files With the Request. You can add file attachment if that is what you asked.
Extracting response from the server :
Let's assume your response is this :
<Response>
<name>StackOverflow.com</name>
<url>http://stackoverflow.com/questions/11186423/how-to-parse-response-of-sample1-to-create-new-sample-in-jmeter</url>
</Response>
Here is what you do :
Right click on The http request you previously added (in step 1) -> Post Processors -> Xpath Extractor
Reference Name is the name of the variable in which you want to store the value. Let's name it url. And Xpath query is Response/url or //Response/url if you get more response tags. If you want the first one //Response[1]/url and so on..
Repeat step 1 (copy/paste sampler and remove the Xpath Extractor you don't need it anymore), and change the Server Name or IP to ${url} which is the value previously returned.
And Voila there you go. Let me know if you got more specific questions. Jmeter is fun.
Per Grace comment :
Wants to extract https://192.168.100.46/updserver/download?action=signature_download&token=
Out of response data :
<responseData class="java.lang.String"><html>
<body>
ERROR=0
MSG=N/A
FILELIST=1555;1340778737370;1526545487;
VERSION=1.002
URL=https://192.168.100.46/updserver/download?action=signature_download&token=
INTERVAL=0
</body>
</html>
</responseData>
This should be pretty simple. Add a post processor -> Regular Expression Extractor and put the following :
Reference Name : url
Regular Expression : (http[\S]+)
Template : $1$
Match No. (0 for Random): 1
So now you have url variable that you can use further in your test as ${url}. Let me know if that works for you. I tested with dummy sampler and it works for me.
This is how I extract some value from url and pass it further as variable so next requests will contain it.
Here are some nice screenshot and wider description about making test in JMeter http://jmeter.apache.org/usermanual/build-web-test-plan.html
Add the Thread Group and HTTP Requests
When this HTTP Requests response with some data (in this example in URL) you want to extract it and us it after
So lets go:
Go to your first HTTP Request after which one you receive response with variable:
Add -> Post Processor -> Regular Expression Extractor
In this window set:
Response Field To Check: URL
Reference Name: MY-CUSTOM-VARIABLE-NAME
define name of variable whatever you like
Regular Expression: permanent.part.of.url.com/([a-zA-Z0-9]*)
so expression ([a-zA-Z0-9]*) is responsible for getting all
occurrences of alphabetic and numeric chars after meeting permanent url at start
Template: $1$
only one expression is extracted in our case and it need to be read
Match No. (0 for Random): 1
in this case there is only one match, but if more occur you can
choose which one use
Now put extracted value into next HTTP Request
Path: some.other.url.com/${MY-CUSTOM-VARIABLE-NAME}
remember that you read JMeter variables with this pattern ${}, so
use ${MY-CUSTOM-VARIABLE-NAME} whenever you need this value
Run your test and check what did you get in url of your request with MY-CUSTOM-VARIABLE-NAME
Experiment with regexp to get desired output.
