I'm a newbie to jMeter, so please bear with me.
I've been assigned the task of testing how an e-commerce website responds under load. I've managed to set up basic tests in jMeter that basically just repeatedly visit the home page, but I'd like to simulate something a bit more realistic:
User arrives on home page
User goes to catalogue page
User views product
User adds product to cart
User returns to catalogue, selects another product, adds to cart
User removes first product from cart
User proceeds to checkout
User completes checkout process.
I'm having trouble finding adequate documentation to explain how to do this. I figured out that I need a cookie manager in my test so that the user session will be maintained, but I haven't figured out how to get the user to traverse the site in a realistic use pattern (such as the one described above). Can anyone help out with this, give me some pointers as where to look for good examples, etc?
This should be no problem, record or manually create the necessary steps as HTTP Samplers, then add them into a Runtime Controller for example to execute them iteratively.
The individual steps will be executed in the order they are in the tree and, in case Cookies are used to handle session state, you might need to add the Cookie Manager to the top of the tree which will handle cookie headers for each user.
Add some timers to simulate user's think time and scale up by increasing the number of virtual users in the thread group.
Use some listener like the Aggregate Report to view the response times for every step.
Try to read http://jmeter.apache.org/usermanual/index.html at first.
Also you'll encounter the problem that Jmeter can't process dynamic pages:
http://wiki.apache.org/jmeter/JMeterFAQ#Does_JMeter_process_dynamic_pages_.28e.g._Javascript_and_applets.29
Does JMeter process dynamic pages (e.g. Javascript and applets)?
No. 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.

Let's say I use Background feature which has the below steps:
Background: My pre-requisites
Given Step one
When Step Two
Then Step Three
....
Then Step Fifteen
So basically my Background has 15 common steps that is required for a set of scenario to run.
My question is : Is it possible to use the Background title My pre-requisites in other feature files, instead of writing down all the 15 steps as Background? Or is there any other way to handle this more gracefully.
You can create a before hook to code the background logic and reuse it across any feature file. Even tag the hook so u can filter out scenarios where u do not want the before hook to run.
Alongside the existing answer, you could also write a new step that compresses the functionality of the 15 steps into one or two steps that express what you are setting up.
The questions revolving around it are these:
Does the business need to know how the user will interact with the site to get to the point where you are ready to begin the test?
Can you bypass how the user will interact with the site to get there without information surrounding the test getting lost in translation between the dev team and the business?
For the former, I would go with a Background. The latter, I would go with a Hook.
For example:
I need to register a user in order to log in as them in my test. The Givens will start at me logging in, so I'll register the user through an API in a Hook.
I need to register a user in order to test the functionality of a new user on exiting the form, and various items surrounding registration, so I'll register the user, starting with some Background steps.
Can we have a script which will crawl through the entire website to figure out if there are any pages which are taking more time to load (some pages under a particular category were taking more time to load) in selenium Webdriver or jmeter
For JMeter you can use HTML Link Parser configuration element for this purposes. From the documentation:
Spidering Example
Consider a simple example: let's say you wanted JMeter to "spider" through your site, hitting link after link parsed from the HTML returned from your server (this is not actually the most useful thing to do, but it serves as a good example). You would create a Simple Controller, and add the "HTML Link Parser" to it. Then, create an HTTP Request, and set the domain to ".*", and the path likewise. This will cause your test sample to match with any link found on the returned pages. If you wanted to restrict the spidering to a particular domain, then change the domain value to the one you want. Then, only links to that domain will be followed.
More information on above approach and a couple more options: How to Spider a Site with JMeter - A Tutorial
Remember that JMeter is not a browser hence it doesn't execute JavaScript so your results may not be precise enough as JMeter doesn't measure the time required to actually render the page.
I want to test a page.Where i want to fill up the fields like first name last name etc.and after going two pages further if i come back to the original page by using back navigation ,data entered for first name and last name remains the same.or it is filled up.
In jmeter i want to check the same if data entered for the fields remain same if i navigate back .
How can i achieve this.
I tried gving url directly in the path its not happening since it is not the way.
please help me since i'm new to jmeter.
You need to understand 2 things. How JMeter works and how your application works.
JMeter only captures data that is communicated to server. It does not matter how data is entered from UI. It does not check if data retains in the fields or not. It only records the request that is sent by your application to server-side.
So, if you understand above, you also need to understand how your application sends data to server. Does it sends the request as you move from first page to second. Or does it send (Submit) data on final page.
Either way, JMeter is not a tool to test if your form fields are retaining data in them as you navigate between pages. As mentioned earlier it only monitors data requests/responses.
Selenium seems a better option for your test requirement.
Please read the apache documentation carefully:
JMeter is not a browser. 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 viewed at a time).
First, you have to understand how JMeter works!!! To do the Functional Testing, Selenium would be a good choice.
Thanks
I wrote test case using selenium webdrive. also i use junit.
Now i want to test that test case for 100 + users.
So i use treads in that application, but i can go up to that much of users because my memory in not enough for that(open 100+ browsers).
So is there a way to test this in Jmeter.
I can't use badboy recording and import it to Jmeter because somehow my application doesn't support it. (the replay doesn't work in badboay).
Please help me to solve this problem.
Thanks
JMeter offers it's own recording solution - HTTP(s) Test Script Recorder. You can record your test case with it and then try to replay.
If you need to check only unauthenticated navigation, like accessing different pages by anonymous user it should work as a charm. However if you test assumes authentication (log in), creating or updating some stuff, etc. you may need to use HTTP Cookie Manager to deal with user authentication and Regular Expression Extractor Post Processor to fetch dynamic values from responses and add them to next request.
There are some more components you may wish to consider adding to make your test look like more realistic:
Add HTTP Header Manager - to set different headers like User-Agent, Accept-Language, etc. - what real browser does
Add HTTP Cache Manager - to simulate browser cache
Make sure that "Retrieve all embedded resources" property of HTTP Sampler is checked - to simulate parsing css, images, scripts, etc.
Make sure that "Use concurrent pool" is enabled and has size from 2 to 5 threads - as browsers download embedded stuff asynchronously in several threads
Make sure that you filter out external domains in "URLs must match" field - you unlikely want to load test Google Analytics or external banners or whatever
I need to display pages in a tutorial fashion. I looked in to netsupport, beamyourscreen and other possibilities but, I do not want the viewers to download anything. I cannot use gd / send screenshots due to audio / video instructions embedded in some of the pages.
Basically, I need the ability to "refresh" a users browser window to a different page via an interface on my end. Whether via a form submission, javascript or any other type of "controller" that allows me to change the page on the viewers browser. PERL preferred but, PHP / javascript whatever works and is cross browser. I set up a simple javascript page forward timer that "works" but, page load times and conversation interruptions are a huge factor.
The entire tutorial website will be developed around this ability.
I was looking in to curl / cron / wget methods but, found little information.
I have seen forum and chat scripts that basically perform a similar task but, there must be a simple(ish) solution in leau of hacking up another script to suit my needs.
I do not want others to control the pages either. The site really, only needs to be accessable during the tutorial however, It "could" remain web accessable as long as user interaction was normal unless (being controlled).
The initial site concept is based on instructing people how to properly introduce new pets into a home. Will be operated by a veteranarian that saved my pets life. I wanted to give something back.
Possible? I really appreciate simple examples etc...
You have no other way but to keep polling the server for "instructions" using javascript. No, you can't send nothing to the end user browser, neither curl nor wget.
Mainly, you'll have to set up a simple request/response protocol between the browser and the server.
If you want to go deeper, you can use something like cometd/meteord/etc. If not, a hidden iframe that reloads himself and receives pages with javascript code for the needed actions can do the trick.
Another alternative.
With javascript dopolling and single character flatfile. Have a simple one character flatfile with a single var. Write it in perl (it is faster and uses less resources than php). The parent script calls a javascript variable in a flatfile. It hits the flatfile and goes wherever the var sets it. The flatfile is written to by the controller. Done.
I guess you could also rename an empty flatfile and use that as the controller. I am usure which is faster, open and read a specific file or hit the directory and return the file name. On the controller side, opening and writing to a file vs renaming a file. Maybe they counter each other in resources and time?
This way the site can act as a normal site. When you want to have remote users see a "presentation" (automatically being shown the site pages at the controllers pace), the controller activates polling and tells the viewers to push a start button. This allows a remote instructor to load pages for the viewers at his leisure.
It is a simple solution that works with nothing really sophisticated going on. No frames are needed either. Just need javascript enabled.
Any better suggestions are welcome!
It occurred to me that what you might want to use is HTML Push technology. Check out the wiki, they have several links. I have never used it myself
