I am trying to catch the element "VIEWSTATE".
I am able to catch the "VIEWSTATE" on the first page, but not on the next.
On next page, the element is dynamic.
How do I catch the viewstate Dynamic element on the second page?
See images below:
The first page
The second page
My expectation is that your login fails, most probably due to missing HTTP Cookie Manager.
Also be aware that JMeter's Post-Processors follow Scoping Rules so moving the extractors to be the children of the relevant requests could also be a reason as sub-samples may not contain the dynamic parameters you are looking for and variables extracted from main sample are simply being overwritten by the sub-samples.
See ASP.NET Login Testing with JMeter article for example .NET based web application login test plan.

Trying to test JSF2.2 application in jmeter5.3. Getting javax.faces.application.ViewExpiredException
in each request. Using Regular expression extractor to read view stateenter image description here.
Looking into this answer
The ViewExpiredException will be thrown whenever the javax.faces.STATE_SAVING_METHOD is set to server (default) and the enduser sends a HTTP POST request on a view via <h:form> with <h:commandLink>, <h:commandButton> or <f:ajax>, while the associated view state isn't available in the session anymore.
So you're sending stale viewstate parameter, check JMeter Scoping Rules user manual entry, you need to extract the ViewState not only once, but from each and every subsequent page so if you placed Regular Expression Extractor as a child of a single request try moving it one level up
Few more hints:
Using regular expressions for extracting data from HTML is not the best idea, I would suggest considering switching to CSS Selector Extractor instead
According to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.4.1 or whatever is the latest stable version available at JMeter Downloads page
jmeter http request results in a page that has div's, but the div's do not contain the rest of the http page.
If I use a browser's developer's view, I can expand the div's to see the rest of the http page results.
How do I get jmeter to show everything that is below the div's? The problem with getting all of the embedded resources is that the embedded resource shows ALL of the possible resulting page code for many different pages. I simply need the RESULT of ONE page to do testing that is specific to THAT page result.
You need to tick Retrieve All Embedded Resources on "Advanced" tab of the HTTP Request sampler (or even better HTTP Request Defaults). If you're receiving resources you're not interested in you have URLs must match input which acts in 2 modes:
You can put specify URL pattern which will match your ONLY ONE PAGE
You can specify URL pattern which will not match specified pages, i.e. something like ^((?!google|facebook|cdn|yahoo|microsoft).)*$ will exclude requests originating from google, facebook, cdn, yahoo and microsoft domains.
Patterns should be in form of Perl-5 style regular expressions. See Excluding Domains from the Load Test for more details.
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
So if you "divs" are populated by AJAX calls - JMeter will not execute them automatically, you will need to add the relevant HTTP Request samplers to mimic each AJAX call separately. As real browsers execute JavaScript asynchronously (in parallel) you should put these requests under Parallel Controller
And finally to put everything together it makes sense to place all the requests under Transaction Controller so you could measure how much time does whole sequence take.
I have a form, which is inside a div on page. When page is loaded, form start to load with a loading screen. JMeter capture it, when page is loaded, it doesn't wait for the form, so page loader is on 0 % when I view results. I tried to use Constant Timer to delay processing. JMeter says too early in this case, that request is successful, because a failure can happen during loading of input fields.
JMeter waits for the whole response with one little exception, as per JMeter project main page:

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 your form is being loaded via AJAX request JMeter won't automatically execute it, you will have to add a separate HTTP Request sampler to invoke the relevant AJAX request(s) which will load your form.
In order to mimic real browser's behavior you can put the main and the "AJAX" requests under Parallel Controller (you can install it using JMeter Plugins Manager)
Scenario:
in response to api request we get a html page as response, we need to accomplish the page with details and need to 'submit' that.
In JMeter:
-- I am able the to save response as a page to html
-- Need to submit page with one textField, one dropdown value
Is there possibility, that we can automate these with JMeter?
Thank you.
I tried my best, can any one please help on this.
Just record your test scenario using JMeter's HTTP(S) Test Script Recorder, it is capable of capturing both GET and POST requests and converting them into corresponding HTTP Request samplers.
Alternative options of recording JMeter tests are JMeter Chrome Extension and Badboy.
If it misunderstood your query and you are asking about the ways of automatically detecting and submitting forms using random dropdown or radiobuttons values in JMeter test you can take a look at HTML Link Parser
In my script i have multiple checkboxes,upon selecting which it populate values(like in first group -- Phone,tablets and in other group it --mac,android).I know that jmeter does not support javascript.If i want to automate it in my script that it selects random checkbox during execution.How can i do that?
There are two ways webpages handle dynamic data population.
Pre-caching
All the needed data is fetched from the server during the initial page load, and as the user makes selections, checkboxes or drop-down boxes or tags etc, the data is filtered on the client end and presented to the user. All of this happens through JavaScript execution on the front end and there is no server interaction. If you used JMeter proxy to record the page load, the pre-load should already be included in your test.
In the traditional JMeter testing sense, the subsequent UI interactions cannot be tested with JMeter - as there are no server interactions to simulate. However you can use the web-driver plugin to simulate and measure UI interactions if you so desire, with certain performance caveats as noted on the plugin webpage.
Lazy Loading
Only a minimal amount of data is fetched during page load, and when the user makes a selection a HTTP call (usually a XHR call) is made to fetch additional relevant data from the server. You can use JMeter proxy, fiddler, wireshark or any other HTTP inspection tools to capture the information in this call and convert it to a JMeter HTTP sampler.
The HTTP request url or body should contain parameters indicating what selection the user made in the UI, You need to parametrize/randomize this value to simulate random checkbox selections.
