Is there any option how to simulate keyboard typing in jMeter? Ive got filter field with autosuggestions and I want to test response time of it. I want to start typing something like "W","Wa","Wash","Washi" etc. but for values loaded from CSV.
JMeter operates on HTTP protocol level, not browser level. Therefore you shouldn't try to emulate typing. What you can do is to capture (record) HTTP request triggered by such change, and later run this as part of your JMeter test.
My advice is - try not to overcomplicate it. JMeter (or perf testing in general) & async calls can be tricky!

i have a scenario, as given below
once the user navigating to planning page and
clicks on a menu,
it will open the lists of recipes in week wise.
if the users wants to add a recipe for a particular, it has an option to click on '+', which will open a popup window which has all the recipe details available.
I have recorded the scenario using JMeter and it has the dynamic values like __VIEWSTATE and ___EVENTVALIDATION etc., and correlated them as well.
But at the 4th step, in the jmeter instead of proper response body and the below message is displayed.

Any suggests
Make sure to add HTTP Cookie Manager to your Test Plan
Make sure that your correlation really works, i.e.
associated JMeter Variables are there
they have correct values (like you extracted the dynamic parameter fully)
depending on your application and extra step might be required like URL-encoding the parameter or vice versa
You can use Debug Sampler and View Results Tree listener combination in order to check these variables
Use an external sniffer tool like Wireshark or Fiddler to capture the requests from JMeter and the real browser, the requests must be exactly the same including:
URL
Headers
Request body
all the dynamic parameters must be properly correlated. Given you will send the same request you should get the same response
When we try to encrypt and decrypt the application for front end request and response data,
Window object is not getting support in Jmeter.
As it generate 2 session id .
Kindly let us know any method in Groovy to support .
Window object is specific to the browser
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 there is no equivalent in any language supported by JMeter's JSR223 Test Elements
The options are in:
Use WebDriver Sampler for getting the session IDs you're looking for, they can be passed later on to "normal" HTTP Request samplers (but this way each JMeter virtual user will kick off a real browser instance)
Extract the code responsible for request encryption and session ID generation using browser developer tools and convert it to something JMeter could execute (remove the browser context), preferably in Groovy as it's the most performing scripting option
i am still new to JMeter and i was assigned to a work that I will need to use JMeter to perform automation testing. The idea is to write script using JMeter and run the script to fill in the forms in the website. I was curious that can JMeter use different data from the database to fill in the form of the website everytime it execute?(unique data for every user)
I have followed this tutorial (https://www.blazemeter.com/blog/fill-forms-and-submit-with-jmeter-made-easy/ ) and it succeed, however, when i try to change the parameter name (to some other names that do not matches the field name found in the inpect mode), it still works. So i was wondering how JMeter knows where to put in the parameter even i have change to a wrong field name?

Browsers don't do any magic, they execute HTTP Requests, wait for response and render it. JMeter in its turn can execute the same HTTP requests so traffic would be the same, however it will not render the response, but rather measure the time and collect some more metrics.
If you change the names of the inputs in the form most probably the request will be successful, to wit you will get HTTP Status Code below 400 hence JMeter will mark the result as "green", however if you inspect the response using View Results Tree listener you will see that the form is not filled and/or you still at the same page.
If you want to use JMeter for checking the data returned by the application you're testing consider using JMeter Assertions to test presence of expected values, absence of errors, set response time thresholds, etc.
You can automate the form submission or order placement usin JMeter. You can JMeter for API testing as well by adding assertions. But the main purpose of the JMeter is to test the performance of the application. Its not like selenium which performs actions on the browser whereas JMeter sends the request in various protocols to relevant server and can also simulate many users at the same time.
If you want to do extensive automation testing,JMeter isnt the ideal tool for that.
You can use webdriver sampler to run the selenium with jmeter. It requires to configure sampler and browser config which are plugin and can be downloaded using plugin manager.
For more info:-https://www.blazemeter.com/blog/jmeter-webdriver-sampler/
Now, without the plugin it is working on protocol level and not on the frontend as pointed out in the above comments.
So, yes it can depend on which layer you want to work. It can work on frontend like selenium using the webdriver plugin and can submit the form with different data as a direct request to the server without using the frontend/GUI.
Hope this helps.
It depends on what you are trying to automate. If you plan to automate API invocation where there are some pre-requisites like grabbing tokens, cookies, session IDs from the browser, then JMeter can probably be used where existing JMeter capabilities can be leveraged using BeanShell scripting and other plugins.
But if you plan to have a full blown UI automation framework then JMeter might not be an ideal choice.
I wanted to know if JMeter has a option where you wait until some element disappears.
Example a loading bar only once that has completed or no longer visible then to carry on. (Also being able to monitor the length of time taken)
I have through about writing it as a webdriver test and then running it as a Junit test in JMeter but wanted to know if there is a simpler solution.
Any ideas welcome :)
First of all you need to realize that JMeter is not a browser
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 JMeter doesn't execute any client-side JavaScript, the only way of implementing "wait until" option is using While Controller in order to re-execute the same request again and again until response data will contain (or stop containing) the element you're looking for.
If you need to evaluate client-side JavaScript the only option would be going for Selenium. I would recommend using WebDriver Sampler instead of going for JUnit as this way you won't have to recompile your script for any change, it will be inlined into .jmx
You can use Transaction Controller to monitor the time taken by the whole process and to wait for a change , have a look at this:

I am using Jmeter(2.3.2) to create script for one of my application with a scenario which has flow for 4 to 5 pages. I have recorded the script using HTTP Proxy Server. The scripts has been generated successfully under Thread Group >> Recording Controller.
After running the scripts (Threads- 1, Ramp Up period - 1, Loop Count - 1 ), below are the observations I noted in View Results Tree:
The Result Tree view shows all as Checked(Green) - OK
The Sample result for all screens shows Error Count as 0 - OK
But in the response tab when I try to view the results by using 'Render Html' response data - the response data shows the same response for all the requests.
I am getting the response data of the first request for all the other requests.
I am not sure, whether the Jmeter script generated is functional or not? What is the cause for getting the same response data for all the requests?
Please, can anyone let me know what may the issue?
I bet that the same page you're observing is a kind of login page or dashboard which is accessible by unauthenticated user.
First of all make sure that you have HTTP Cookie Manager added to your test plan. It represents browser cookies and deals with user sessions and cookie-based authentication.
If it doesn't resolve your issue the problem is bigger and you will need to do some extra stuff. Modern web applications use multiple mechanisms of current state of things storing and managing, security enhancements and so on. From JMeter's point of view it results in dynamic mandatory parameters. The process of these dynamic parameters extraction from previous request and adding them to next request is called "correlation". So you need to do the following:
Detect which parameters being sent by a recorded script are dynamic. The easiest way is to record the same scenario several times and inspect request bodies to see what is being static and what changes.
Once you figure out which parameters are "interesting" you need to locate them in the first response body/headers/etc.
As soon as you have identified what necessary parameters are and where they live you need to use one of JMeter's PostProcessors to extract required values from previous response and save them to JMeter Variables
Once you have a JMeter Variable it can be used wherever required.
Depending on response data type the most commonly used JMeter's Post Processors which provide correlation capabilities are:
Regular Expression Extractor - the most commonly used test element which covers >90% of needs.
XPath Extractor - better to use against XML data i.e. for testing SOAP Web Services.
CSS/JQuery Extractor - when you need to fetch something from complex HTML where Regular Expression Extractor is useless.
So for putting everything together loog for "jmeter correlation" in your favorite search engine or see ASP.NET Login Testing with JMeter guide.
First JMeter 2.3.2 is WAY TOO OLD (10 years old), upgrade to JMETER 2.11.
Second, Jmeter cannot guess that the response if KO if the returned code is 200, so you need to add Response Assertion that will check for some text you expect in the page.
