Tried to capture request having only specific url e.g "www.yahoo.com" in URL but JMeter capturing all the requests from google, mozilla etc
Tried with patterm :
.*www.yahoo.com.*
But not working.
I cannot reproduce described behaviour using latest JMeter 5.1
According to the HTTP(S) Test Script Recorder documentation
Patterns to Include Regular expressions that are matched against the full URL that is sampled. Allows filtering of requests that are recorded. All requests pass through, but only those that meet the requirements of the Include/Exclude fields are recorded. If both Include and Exclude are left empty, then everything is recorded (which can result in dozens of samples recorded for each page, as images, stylesheets, etc. are recorded).
It means that you will see all the requests in the View Results Tree listener, but only those which match your regular expression will be stored under the Recording Controller
Also be aware that www.yahoo.com and yahoo.com are different servers, you might want to reconsider your test scenario.

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
Can someone please give me an explanation of AJAX Defaults Config or what is the role of it in Jmeter?
I tried to search for an answer in Google but I can't find a definite definition of it.
As of JMeter 5.1.1 there is no such a thing as AJAX Defaults Config in JMeter Components so most probably you're using some form of JMeter Plugin which is not publicly available. If this is the case you should reach out to the plugin developers/maintainers for the clarification.
For the vanilla JMeter, 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).
Therefore JMeter is not capable of automatically execute AJAX requests because J letter stands for JavaScript
If you need to properly simulate AJAX requests you need to add a separate HTTP Request sampler per AJAX call and put them under Parallel Controller to ensure
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 have a search form which would open a list when 2 characters are typed. I would like to measure that time it takes to open and load the list in jmeter. How can I do it?
If you look into your "Network" tab of your favourite browser developer tools you will see that each time you type a letter or digit in the search field the browser sends a HTTP request to the backend server and it responds with search suggestions:
So all you need to do is to simulate these requests using JMeter and measure the response time.
You can even record these requests using HTTP(S) Test Script Recorder, Badboy, JMeter Chrome Extension, whatever
There are two things, I would like to quote:
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).
From JMeter Wiki
JMeter does not process Javascript or applets embedded in HTML pages.
JMeter can download the relevant resources (some embedded resources
are downloaded automatically if the correct options are set), but it
does not process the HTML and execute any Javascript functions.
If the page uses Javascript to build up a URL or submit a form, you
can use the Proxy Recording facility to create the necessary sampler.
If this is not possible, then manual inspection of the code may be
needed to determine what the Javascript is doing.
Solution #1
Whenever you type each character, check any service call to the server. This can be captured using browser developer tools > Network tab.
E.g.
If you type iPhone, there will be six service calls to the server. By measuring each call individually, you will be able to understand, how your application behaves under the load.
Again this is a service call, not the UI rendering.
https://example.com?q=i
https://example.com?q=iP
https://example.com?q=iPh
https://example.com?q=iPho
https://example.com?q=iPhon
https://example.com?q=iPhone
Solution #2
By leveraging Selenium WebDriver in your JMeter Test plan, you can measure the end-to-end response time.
Please refer this Blazemeter article and this blog for more details.
Visit JMeter Plugins website and search for Selenium to read more details about Selenium WebDriver.
I was using Jmeter HTTPS Test Script Recorder to record a login request.
Please see the snapshot, I already added the URL patters to exclude the .js files, but I still get the js requests.
Why it's failed?
You can check that if you look at the contents of the said requests. Most likely they are GET requests, and most likely they have one or more Parameters. Regex .*\.js looks specifically for .js at the end of the URL. But if GET request has parameters, on recording its URL would look like <...>.js?param=value, so the regex .*\.js will not match (although the name of the request will still be the same).
So you need to specify 2 regex exclusions: .*\.js and .*\.js?.*
I know that it doesn't answer your question, but actually excluding images and .js files is not something you should be normally doing. I would rather use that field to filter out the "external" URLs, which are not connected to your application like 3rd-party banners, widgets, images, etc. - anything which is not related to your application under test. Even if you see it in response, these entities are being loaded from external sources which you cannot control so they are not interesting and the picture of your load test might be impacted.
So I would suggest the following:
In "Grouping" drop-down choose Store 1st sampler of each trade group only
Make sure that Follow Redirects and Retrieve All Embedded Resources. are turned on in the recorded requests. If not - enabled them via HTTP Request Defaults. Also check Use concurrent pool box is ticked as real browsers download images, styles and scripts in multi-threaded manner.
When it comes to running your test add HTTP Cache Manager to your test plan as well-behaved browsers download images, scripts and styles only once, on subsequent requests they are being returned from browsers cache and this situation needs to be properly simulated
For anyone else arriving here from google looking for an answer to this question:
You may simply be looking at the wrong place.
If you're looking at the workbench results tree, you'll see all requests. They are not filtered here. I've thought this was a bug with JMeter more times than I care to admit.
Instead, look inside the Recording controller tree (which is collapsed by default), where the results are in fact being filtered:
