I have a Jmeter script for an application for which i get pop up error message intermittently. Where as in jmeter we only come to know that flow got terminated by some failure.But we wont come to know the occurrence of Error pop -up message.
My requirement is if we encounter pop up error i want to write to an external file saying that ,the current page got failed due to pop-up error message.
If we can write the error message it's really great. I'm as of now not getting idea to achieve this.
Please can anyone help me in this. or can provide any hint to do R&D.
Thankyou in advance.
Updated the question with screen shot of error message.
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).
Looking into your screenshot, it is a form of JavaScript popup, most likely window.alert so there is no way to detect it via JMeter.
You can add i.e. Response Assertion to your test in order to introduce some pass/fail criteria, i.e. if you were in the middle of some transaction when the error occurred it should not finish successfully resulting in missing expected entry in the web page (or database), so you can conditionally fail relevant sampler(s) in this case. See How to Use JMeter Assertions in Three Easy Steps to learn more about the concept.
Alternatively you can use WebDriver Sampler plugin which provides JMeter integration with Selenium browser automation framework which drives a real browser, so you will be able to capture this popups and record the page titles/take screenshots, check out IsAlertPresent() class for more information.
you must get this error response in your jmeter request response.simple answer.Have a regex to extract.

I am doing a performance testing in Jmeter I have added the controller and request, but my problem is when I run the script the requests are not automatically/manually navigating to the next controller
Scripts here
Script results here
I my case the scripts jmeter_login_and_view_dashboard running without any issues but is not navigation to next controller login checker or actions per login
I don't know what I am missing
Thanks in advance
We don't know as well because your screenshots don't tell the full story.
I can think of the following reasons:
You have Flow Control Action sampler somewhere which stops the test
An error occurs you have Thread Group configured to stop the test in case of error
There is an If Controller and the condition is not met
The controller is using a CSV Data Set Config and the CSV file is not present
So take a look at jmeter.log file, normally it should provide at least a clue regarding what went wrong.
I am new into Jmeter and trying to do my first load test, When I get my data from website it is always come in .txt form and when this data I try to run my test it fails,
It's hard to say what is wrong without seeing the "Sampler result" tab screenshot for at least one failed sampler.
Going forward consider providing as much information as you can, i.e.:
Screenshot of the HTTP Request sampler
Screenshot of the View Results Tree listener demonstrating Sampler result, request data and headers and response data
At least relevant parts of the jmeter.log file, better with the debug logging for the test elements involved enabled
I'm using Jmeter to perform load test on Moodle application
I followed the below steps to replicate a simple "add company " test scenario
1: Recorded the browser actions through HTTP Test script recorder and created a test plan with thread user of 1
2: Added HTTP Cache Manager,Added regular expression extractor for retrieving dynamically generated session for login HTTP request.
For Http request of adding new company, addded user parameters containing new company name
I run the test, everything seems ok in the view results tree- response section (response code: 200,response message:OK), all the required variables are passed in the HTTP POST
PROBLEM: New company added through Jmeter test is not reflected in UI of the moodle action
Can any of you please let me know
Is there something I could be missing or anyway I can debug the problem?
P.S: I'm new to Jmeter and looked around a lot for data inputted through Jmeter not being displayed in the UI of the web application,dint find useful results.
The answer to questions of this sort is almost always that you missed some necessary dynamic value besides session ID which you did catch.
An HTTP200 response just means the server returned a "good" response. Which could also happily contain an error message.
I would check the actual html body of the returned response for any errors. Checking the log on the server side can give you clues to what went wrong sometimes. You should also try adding a cookie manager.
Run your test with 1 virtual user in GUI mode with View Results Tree listener enabled and inspect responses to see where your scripts fails. My expectation is that you simply cannot log in.
See Moodle-JMeter-LoadTest.jmx file for reference, it uses XPath Extractor to get session key and course id.
I don't think you can test using JMeter. Try JUnit Test cases instead http://jakarta.apache.org/jmeter/usermanual/junitsampler_tutorial.pdf
I am running a JMeter script to hit a web page that opens another link to a shopping cart. There are a few different urls that JMeter recorded for me using the HTTP Script Recorder. When running the JMeter script, I receive no errors in any logs ( JMeter log and a few summary report / View results tree logs ). I even added a Constant Timer to some of the pages that do actually take a few seconds to load when hitting them manually in a web browser. In the end, I cannot see what is happening, but JMeter also does not indicate any errors. How can I confirm that each url hit is actually succeeding so that the shopping cart actually gives me my item when JMeter is done?
If JMeter is able to make a http request successfully, it will be always green in View Results Tree (200 http code). It does not mean that your test is correct - ie even if the login is not successful JMeter does not report it as error/failure unless you validate the response.
I think you need assertions to ensure that the http response you get is as you are expecting.
I recently recorded a test script in Jmeter intended for use as a load test script (using this handy set of instructions. The recording itself worked great and I even figured out how to grab and parametrize the session ids and timestamps. However, if I run the recorded steps just as they were recorded some of them don't work -- they generate "500--Server encountered and internal error ...nested exception is java.lang.NullPointerException" The failing steps are all Ajax calls that populate sidebar elements. If I copy the request GET call (Request tab, ViewResultsTree) and paste it into a browser I get the exact same error. Do I need to record my script differently, or hand-code the ajax calls? Other, earlier steps work correctly and send the expected POST data, so it isn't the application under test or forgotten proxy settings. Currently running against Firefox 3.6.10
Any suggestions on how I can debug this would be greatly appreciated.
The first thing I'd do is determine if the java.lang.NullPointerException is happening on the client side (JMeter) or on your server. If it is happening in JMeter, than something is terribly wrong with either your script or with JMeter.
But assuming that the error is encountered on your server, then looking into the cause of the exception may shed light on what is wrong with the request issued by JMeter. Do you have access to the code where the exception is thrown?
I would also recommend comparing the request in the recording with the request that generated the error. You may need to determine which parts of the request are session-specific and ensure those fields are populated correctly.
It sounds like Jmeter isn't executing the AJAX calls, and this can be fine depending on your site. Can you simply do an HTTP request to get the pages the AJAX calls populate?
I would recommend reading this post, as it looks pretty good.
I've seen that situation caused by a few things:
a page is required to load and be cached BEFORE making the failing request;
the failing page needs to automatically redirected to work properly;
the failing page has sub-requests JMeter failed to record. Devs can help with this.
Hope this helps.
