I have an API url and body data in xml format.
How to do load testing of available API url using JMeter?.
I need to check the API performance for multiple user login.
Add a Thread Group to your Test Plan and specify the desired number of threads (virtual users), iterations and test duration
Below setup will run the request with 10 users for 1 minute:
Add a HTTP Request sampler as a child of the Thread Group and specify the URL and the body there:
You may also need to add HTTP Header Manager to send the relevant Content-Type header
Run your test in command-line non-GUI mode
Generate HTML Reporting Dashboard and analyze the results

I'm trying to build a login script for my website load testing on Jmeter, but I am not able to do so. I have added the cookie manager and cache manager too. I already recorded the script through http script recorder and made a transaction of the same and running test on this recorded scripts. The website is using spring security for login security.I tried to add Beanshell Preprocessor into the login sameple request for gzip deflate and passed the form parameters but still the server is not authenticating the request.
Most probably your login request doesn't work due to missing or improperly implemented correlation.
Modern web applications widely use dynamic tokens for various reasons starting from client-side state tracking like JSESSIONID and ending up with security mechanisms like CSRF
The easiest way of identifying dynamic parameters is recording your test scenario one more time and comparing resulting .jmx scripts. All parameters which will be different are a subject to correlation, to wit you need to:
Extract them from the previous response using a suitable JMeter Post-Processor
Replace recorded hard-coded values with the JMeter Variables from step 1

Single page application with specific organizational service accounts uses microsoft authorization (2.0).
To pretend in JMeter as user working with this application, it is enough to have Bearer access_token and then pass this Bearer in header of JMeter script requests.
I can manually login with user credentials in browser, get Bearer and set up it as variable in JMeter in API requests headers and successfully continue to work with application functionality.
Also I can login in WebDriverSampler (and I suppose, can emulate with WebDriverSampler another user's actions with application like in "browser").
What is the simplest and shortest way, having all above, to get Bearer somehow for API calls in a script without time-consuming or programming-oriented complex solutions? Is it possible somehow to use WebDriverSampler requests for parsing Bearer?
On this stage, the goal is to collect (and generate) Bearers, which have long time of life, with intention to use this set of Bearers for multi-session JMeter "users" later. (Because users amount is under cost constrtaints with users service accounts, i.e. I have 1 provided user only).
Will be very appreciated for grace tips and advices with such kind of problem.
It should be possible to use i.e. BrowserMob Proxy for capturing the traffic between the browser orchestrated by the WebDriver Sampler and the backend, this way you will be able to extract Authorization header value and i.e. store it into a CSV file for later re-use.
In general it should also be possible to replicate the browser's authentication flow with JMeter's HTTP Request samplers as browsers don't do any magic, they just send HTTP Requests and display the responses so well-behaved JMeter test should generate the same network footprint as the real browser does
Hi I would like to test using Jmeter for my application which has login page. I am able to write Sample http request for login page which is working ( passing username and password as POST parameters).
But the another Sample HttpRequest (home.do) is not working which is again redirecting to login page. I also added HttpCookieManager at Thread level. Not sure why the authentication is not carry forward to other pages, Can anyone please help me on this.
Most probably your test doesn't work due to missing or incorrect correlation. The absolute majority of modern web applications use dynamic parameters for different reasons (client state tracking, security, etc.) so you need to setup your test plan like:
Open Login Page (usually GET request)
Extract dynamic parameters
Perform Login (usually POST request), provide credentials and dynamic parameters extracted from the previous request
Extract dynamic parameters
Open Home Page (usually GET request)
etc.
You can extract dynamic parameters using JMeter Post-Processors
Also make sure you add HTTP Cookie Manager to your Test Plan to represent browser cookies and deal with cookie based authentication.
BTW, you can quickly build test plan "skeleton" by simply recording your test scenario using HTTP(S) Test Script Recorder
How to test load on an authenticated website using Jmeter?
There is a user login page on application start where we need to enter credentials to access the application.
Just record it using HTTP(S) Test Script Recorder,
JMeter will capture associated request(s) and generate the relevant HTTP Request samplers.
If you will be lucky enough - you will be able to successfully replay the recorded script.
If not - most probably you will need to perform correlation - the process of extracting dynamic parameter from the previous response and adding it to the next request.

I am trying a Performance scenario where single user logs in to web application.
For that i am using Jmeter and REST-APIs
Here i have to call REST-APIs for that i have used "HTTP Request Defaults", I have created one thread group and added one "HTTP Request Default".
From APIs i have to pass two parameters:
1) User Name
2) Password
What would be the syntax of parameters in HTTP Request Defaults? or what sampler i should use for this?
I have one API link from which we can trigger those parameter, which will get applied on web application.
First of all you'll need a HTTP Header Manager configured to send the following header:
Name: Content-Type
Value: application/json
Elsewise your request may not be processed as needed
The sampler you need to use is generic HTTP Request sampler. The easiest way to provide JSON payload is to switch to Body Data tab and put your JSON there as below:
Optionally you may with to use JSON Path Extractor for correlation
See Testing SOAP/REST Web Services Using JMeter guide for a quick ramp-up on the RESTful web services testing domain.
for ease of use
In your Jmeter click on File, select Templates
In the opened window/dialog, select "Building a SOAP web-service test plan"
Click on Create.
It will open a test plan, which should give you a fare idea on how to achieve your scenario.
Hope this will help.
