What I am doing is, I have recorded a download event from APP on Jmeter, when ever i am running this API on Jmeter, a server where any download event is recorded, is showing OR increment that download on that specific time when it was recorded.
How can I use this to get updated data on server when Jmeter is running.
Also need some information on to how to add different valid users on Jmeter.
Thanks,
Abhi
My expectation is that you pass a hard-coded timestamp as a request parameter so you need to figure out the parameter value and substitute the hard-coded timestamp with __time() function which produces current time in different formats controllable via SimpleDateFormat patterns.
Check out How to Use JMeter Functions article for comprehensive explanation
In regards to adding valid users, normally people stick to users which already exist in the system and use CSV Data Set Config to give each JMeter virtual user unique credentials of the real user.
If your application doesn't have that much users you might want to setup a separate JMeter script to get them created as re-using one login with large number of threads is not a good practice.

I'm currently working on making a few improvements to our selenium based UI tests. One feature I'm looking for is a reliable way for our website to detect what traffic is coming from our tests, so I can filter this traffic out of our browser usage metrics and logging.
One thought I had is to set a tracking cookie with selenium that I could read server side to append to my logs/metrics making it easier to filter it out. The challenge here is cookies are domain specific, and as far as I know wouldn't be readable from other sites. Cookies are also a finite resource, and given the size/distributed nature of our website it's quite possible to run into a situation where this could blow the size limit on cookies/headers and cause issues in the page.
Is this my best option, or is there another reliable way to detect from my webserver if my page is being automated with selenium. (I'm not trying to combat bots, we have other systems in place to guard against DoS/DDoS attacks.
When using Chrome, the Selenium driver injects a webdriver property into the browser’s navigator object. This means that for me, adding the following js to my page redirected it to StackOverflow:
if (navigator.webdriver == true) {
window.location = "https://stackoverflow.com";
}
So I guess just replace window.location = "https://stackoverflow.com"; with whatever you want, I'm guessing logging the requests somewhere or somehow excluding them from whatever tool you use to measure traffic.
So, the server obviously needs some token that tells it that a session is selenium based. Given that, here is what I would do.
Create a super simple API on your server. Have that API take the session token of the logged in used and pass that in the API (almost always automatic). When the API receives that session token, mark something in the database (new table or same table that stores session ID's if any).
Have the API flag the session as a test session, and thus not valid for metrics.
This is not a statistically significant impact on any server, so there is no worry about resources or impact.
Should take a very simple code-behind API, a very lightweight table that could simply have a single column with a foreign key to the session id involved. All inserted session IDs in this table, by virtue of existing here, are test sessions.
And then, your metrics recording will need to add a single clause to a query that has effectively "WHERE (SELECT COUNT(sessionId) FROM TestSessionsTable WHERE sessionId = currentIdChecked) = 0"
And that would give you what you need. I am happy to be told of a better solution, but this strikes me as the simplest effort, with the least impact on resources.
As for detecting Webdriver sessions on the client side, you can either use C. Peck's suggestion, or directly call the API from your automation run using the WebDriver's Javascript Executor logic.
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 made a program that gets the data from the clipboard and saves it in a string variable. Then it looks for specific words in that string and generates several URLs. Afterwards it open the browser and shows each URL in an own tab.
Some of my friends already use this program frequently and I want to have some statistics about how often. I simple counter variable would be enough but I need to get access to it.
I came up with two options that could work:
I could send an email to a specific adress every time my app is executed. Then I can track the amount of uses by manually or automaticly counting the amount of emails in the postbox. I think this would be a Vers dirty solution.
I could create and publish a website containing a counter. This counter could be refreshed by my application. This solution is a bit better I think but a lot more work for just one single counter.
Do you have better ideas to solve my problem or is one of mine already a good one?
Thank you in advace!
You can use Measurement Protocol Overview. This provides you statistics of usage your application compared with Google Analytics. You can see even a geo statistic, version distribution, crash reports. It is easy to use it from .net. It is just about requesting http request to google.
I am new to Jmeter testing. Last day my client asked me to test his website for load. I did a normal testing on it but now he wants a scenario where,
"I need to post both text & images with max no of concurrent users.
And also please do monitor the resource usage like how much Ram, CPU & Bandwidth consumption."
I need to find out how many active users can use the site cucurrently.
I referred this, JMeter - File upload and file download scenario but still I am not clear about it. May be because I am new to it.
But I need to login to the URL inhouse.net/redmine
Then I should go to the Home page inhouse.net/redmine/home
and the update profile photo there
How can I do this through jmeter?
Can someone please help.
Thanks!

Get the newest JMeter version from the site, and get JMeter plugins (Extras with Libs Set) from here. Once JMeter and the plugins are installed, you should take your time and read these:
JMeter user manual
JMeter best practices
About performance testing
The third one is really long, it should give you every detail on performance testing, use it only if something is not clear.
Then, you have to record your test steps (the http(s) requests from your browser that you want to simulate), a good guide on that is here.
For the scenario, I'ld use the ultimate thread group from JMeter plugins pack, and slowly increase the number of users from 1 to 1000. Measure how much time does it take for 1 thread (user) to complete the test steps. For example if 1 user takes 1 minute to finish, I'ld start a new thread every 1 minute, up to 1000. (check out timers for this).
You'll have to establish some KPIs, that reflect your needs, (in your case it's upload successful) check out the MSDN guide for more details on this. You'll have to implement these checks in your jmeter scenario (profile) using assertions, to determines if an upload was successful or not.
Don't forget to run your final test in command line mode. (with the -n paramter, no GUI)
For resource usage monitoring I recommend using dstat.
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.
