I have a login form that has form method set to POST, form-action set to a servlet, and an OnSubmit function to check the field data.I want to performance test a file download funcitonality that lies behind this login form. To acheive this i am running a parallel sampler to login and then download the file.
The first sampler is for the login and the second one is to dowload the file.
In the first sampler, I want to POST data on this form using JMeter's HTTP Reqest Sampler.
I have inspected the form and created a sampler with three parameters, the username, the password and one more non-discloseable field. I have set the path to the servlet since it is the one handling the requests for the form.
The post request doesn't do anything in this case.
What should i do or check or modify to make sure that the POST request is hitting the correct endpoint and that it actually submits the form data.
You need the samplers to be sequential, I think if you attempt to download the file without prior logging in - the request will fail somewhere somehow.
If it is not sufficient and you would like to add an extra level of checks, i.e. test that the endpoint returns anticipated response code or has certain text you could add Response Assertion as a child of the request and add pass/fail criteria there.
If you don't know how to properly build login and download requests, the easiest way is just recording them using HTTP(S) Test Script Recorder, JMeter will capture the requests and generate relevant HTTP Request samplers and HTTP Header Managers

I am using Jmeter for testng load balance of website.I written a script to test the scenario like to make the user to login into the website and able navigate the user to the dashboard where he can see the recent data by consuming the protected calls.Here i am able to pass the user login scenario but the jmeter showing fail errors regarding the protected calls.When i am searching the url thing whcih is given by jmeter i able to understand that teh protected calls need user credentials to consume data but it fails due to absence of user login things.
Here i am able to pass the user login scenario
are you sure? If JMeter reports the HTTP Request sampler as successful it doesn't necessarily mean that the login will be successful, it might be the case your application responds with status code 200 and some error message explaining why the login has failed and JMeter automatically treats HTTP Status Codes below 400 as successful.
Try inspecting request and response details using View Results Tree listener which has HTML and Browser modes and double check that you're able to login.
If yes - you might need to add HTTP Cookie Manager or perform the correlation of the authorization header in the HTTP Header Manager for the "protected calls" or something like this
If no - you will need to amend your script so login will be successful. In order to avoid such situations in future you might want to add Assertions to your test plan to ensure that JMeter is doing what it's supposed to be doing
I'm trying to record a script in JMeter. I'm getting a 401 error in the login request. I see that the login request is sending a token to the server and I have to correlate this token however I'm not able to find any token in the response body or response header of any previous request. What should I do?
There are 4 sources where the "token" could come from:
Response body
Response headers (including cookies)
URL (as a result of a redirection), if this is the case you might need to play with Redirect Automatically and Follow Redirects checkboxes in the HTTP Request sampler (or HTTP Request Defaults)
The token can be generated by JavaScript. As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
so if this is the case - you will have to replicate the logic of the associated JavaScript function(s) using JSR223 PreProcessor
I am testing an API endpoint for which there is a form based authentication(for additional security). Can someone suggest how to handle form based authentication in Jmeter. I tried with HTTP Authorization Manage, still my request is failing.
You basically need to submit a HTML Form by sending a HTTP POST request using JMeter's HTTP Request sampler.
Given you provide correct credentials you should be authorized for further actions.
In some cases you will need to perform correlation as you might have to provide a dynamic parameter (or several) along with the credentials as your application can use these parameters for i.e. CSRF protection or for other reasons so make sure to carefully inspect the request sent by the real browser (you can capture the original request using browser developer tools) and if there are any dynamic parameters - you should extract them from the previous response using a suitable JMeter Post-Processor
Once you successfully log in it should be enough to add HTTP Cookie Manager to maintain the user session.
I need to create scenario for user interaction with single-page WEB application. The application does lots of AJAX calls in order to authenticate user and get user data.
So I created simple scenario with HTTP Test Script Recorder and tried to record my script.
Everything went well, however I noticed that whilst request data is recorder properly, the response data is not recorder at all. I tried to enable Add assertions and Regex matching - but that didn't work as well.
Can you please advice how do I record response texts as well?
View Results Tree under proxy will record request, responses during recording.
This is useful to understand where a dynamic field comes from. This will help your find from which response X you need to extract data to inject in request X+N.
I think you may find this option useful to add in user.properties:
proxy.number.requests=true
This will give a number to each request and corresponding sampler so you will be able to find response for the request.
Once you have done this, you will start adding Post Processors (Regex, CSS/JQuery, XPAth ...) to Sampler X to extract data from its response.
This will create variables you can then use as ${varName} in request X+N.
How to use JMeter with ajax request?
I have a button with is clicked and by using fiddler I can find the session id which is being sent to the server.
What should I do next using the JMeter in order to handle this.
EDIT:
Let's say I have in my hand the header which call the request. The JSESSIONID AJAXREQUEST
and so on where should I put it ?...
I putted it in http header manager name and value.
Jmeter will not execute Javascript embedded in your web page. However AJAX request is also a HTTP request that Jmeter will be able to run as a separate HTTP request and upon getting the response you can have post processors (using XPATH or REGEX) to extract the session id in a Jmeter variable.
Alternatively you can record the Jmeter scripts using Jmeter proxy and then all the HTTP requests will be recorded for you and you will just need to attach a post processor manually.
