My JMeter script doesnt download woff, png, jpg. I checked script and all of config elements, no where I am specifying not to downlaod them but still it's not downloading them. Can anyone tell me the reason.
You need to "specify to download them", JMeter won't do it automatically.
Add HTTP Request Defaults configuration element (if it's not there yet)
On "Advanced" tab tick Retrieve All Embedded Resources from HTML Files and Use concurrent pool
It's also a good idea to add HTTP Cache Manager to replicate browser behaviour when it comes to handling resources caching

I am using "Retrieve all Embedded resources" advanced option to retrieve all static content.
It work fine but does not retrieve below .js. Is there any Filter or option in JMeter to get below files ?
I don't see any "below .js", just in case be aware of the following limitation:
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 an "embedded resource" is being triggered by the client-side JavaScript - JMeter won't be able to process the JavaScript hence won't download the associated piece of content. If this is your case - you will need to download it using a separate HTTP Request sampler and put both "main" HTTP Request and the second one under the Transaction Controller to get the cumulative time. If there are multiple occurrences of such assets - put them under a Parallel Controller
I have to record and run Jmeter test using WorkBench so that I have recorded using Proxy[See the image].
Lists all the URLs
I know I can sort/get the urls by using 'URL Patterns to Include' option in HTTP(S) Test Script Recorder. When recording it lists out all the URLs including .gif, .png, .ico etc.
URL Patterns to Include
I have two doubts to clear.
When recording what is the criteria to give in 'URL Patterns to Include' - to record desired URLs only. (Desired URLs I meant is for example, if I am recording a website developed in PhP, I need all PhP links only. ie, home.com/index.php, home.com/contact.php, home.com/about.php). Now it records all the URLs where I cannot see the desired links. How to get .php or main link URLs(we see in browser URL)?
Regarding running a test in Test Plan contains the URLs that I have cut-paste from WorkBench(recorded using Proxy), do we need to add all the recorded URLs including .gif, .png, .ico etc or just add the specific URLs(say home.com/about.php) only? If I run using only the specific URLs, whether the result will be correct as we excluded other URLs like .gif, .png, .css etc ?
You don't need to record these .gif, .ico, etc. files separately as this is not how real browsers work.
Real browsers do main request to the HTTP endpoint followed by concurrent download of so called embedded resources: images, scripts, styles, etc. In order to make your JMeter test to behave more like a real browser you need to:
Exclude these requests from recording. Click "Add suggested excludes" button in the HTTP(S) Test Script Recorder (or even better re-record your test scenario using JMeter Recording Template feature)
You can create a recording test plan by selecting File -> Templates -> Recording -> Create from JMeter's main menu.
When it comes to test execution add HTTP Request Defaults to your Test Plan, switch to the "Advanced" tab and tick Retrieve All Embedded Resources and Parallel Downloads boxes
If there are images, banners, whatever coming from external servers you can filter them as well via URL(s) must match box in form of Perl-5 compatible regular expression.
See Web Testing with JMeter: How To Properly Handle Embedded Resources in HTML Responses article for more information on dealing with embedded resources in JMeter tests.
I am just wondering why do we exclude photos and css files in jmeter script because if i think from end user prospective,images takes more time to load.
The only content to be excluded from test script is "external" content, i.e. any third-party banners, pictures, maps, analytics, etc. content needs to be filtered out.
JMeter test needs to be as much realistic as possible to correctly simulate user activity. So:
Images, scripts, styles, etc. do not need to be excluded from JMeter test
The best way to handle them is as Vinoth S suggests using "Retrieve All Embedded Resources" functionality (and it is also better to use concurrent pool of 2-4 threads for it). The most optimal way of configuring it is via HTTP Request Defaults config element so the change could be applied to all HTTP Request Samplers.
It is also good to add HTTP Cache Manager from "reality" perspective as real browsers download all this stuff like images, scripts and styles, but they do it only once, on subsequent requests the content is being returned from browser's cache and the actual request to the server is not being made.
See How to make JMeter behave more like a real browser guide for other recommendations on how to make your test more realistic.
css/jpg/js files are all embedded static resources in the HTML response you get.
so instead of sending a recorded request, you can select the below option in the HTTP sampler. JMeter will take care of downloading these files for you just like a real browser.
Does Jmeter 2.11 supports pdf editor's data capture?. Kindly anyone advice, how to record pdf data using jmeter 2.11 version. Because our application made up on java and its a web application.
The issue is,
Log in to the application
Click on user information link
The request will be opened in a pdf editor format, where we are updating user information.
Here is the issue, I can not record the pdf editor information. While recording, the pdf editor page is not even opened. I tried to disable my antivirus protection too.. :(
JMeter is designed to functionally test server-side components, whereas opening a PDF occurs on the client-side, albeit after the PDF has been transmitted over the wire to the end-user's browser.
As such, JMeter will only show you:
How long it took the server to process the request and begin serving up the response (PDF) to the browser/JMeter
How long it took to transmit the response (PDF) over the wire back to the browser/JMeter
If you're interested in physically manipulating items on the client-side, which also has the effect of thereby testing the server, check out http://docs.seleniumhq.org/
We are using JMeter's built-in HTTP Proxy to record a test case. It was decided to capture all requests going to the server, and therefore there is no include/exclude rule set in the proxy. My question is whether there is a necessity in load testing to capture calls to JS, CSS, PNGs and other embedded resources?
So, technically speaking if I call a JSP that includes such resources, JSs, CSSs and images then will their timings (such as response time and latency) be automatically included in JMeter? I know that JMeter is not a browser and therefore it cannot execute client-side scripts but does it automatically discover/consider such resources even when there is not any explicit call to them in the test case.
To answer the question,
YES you can remove all embedded resources from being explicitly called. Requests have a checkbox on the bottom that says "retrieve embedded resources". This would grab all CSS, JPG, etc.
It's also a great way to find broken links and resources in a web app.
Yes it does record all those resources you mentioned. If you look at the recorded test you'll see all you CSS, PNG, js etc files listed too. You can simply remove them if you think some or all are not relevant to your test.
