[404-Not found]
Hello All,
I'm running one script having Checkout functionality but my script gets fail at particular page instance giving me "404 - Not found" error in logs.
But while executing manually I'm able to go to the page successfully.Below is the error message. Do i need to pass cookies in the same while execution.
Any help will be appreciated
Most likely this is due to missing or not properly working correlation. You can record the test scenario using HTTP(S) Test Script Recorder but it will be only a "skeleton" of the test containing hard-coded values like IDs or URLs or whatever.
So given you checked something out and recorded the relevant request(s) next time you will try to replay the recorded script you will get an error as the item has already been checked out, so basically you need to find another one to work with.
Normally the situation is worked around as follows:
Record the test 2 times
Identify request parameters which are changing
Using JMeter PostProcessors (the most commonly used is Regular Expression Extractor, however it may vary depending on your response data nature) convert hard-coded recorded values into JMeter Variables
Use Debug Sampler and View Results Tree listener combination to inspect:
JMeter Variables values
Request details
Server responses

i have a scenario, as given below
once the user navigating to planning page and
clicks on a menu,
it will open the lists of recipes in week wise.
if the users wants to add a recipe for a particular, it has an option to click on '+', which will open a popup window which has all the recipe details available.
I have recorded the scenario using JMeter and it has the dynamic values like __VIEWSTATE and ___EVENTVALIDATION etc., and correlated them as well.
But at the 4th step, in the jmeter instead of proper response body and the below message is displayed.

Any suggests
Make sure to add HTTP Cookie Manager to your Test Plan
Make sure that your correlation really works, i.e.
associated JMeter Variables are there
they have correct values (like you extracted the dynamic parameter fully)
depending on your application and extra step might be required like URL-encoding the parameter or vice versa
You can use Debug Sampler and View Results Tree listener combination in order to check these variables
Use an external sniffer tool like Wireshark or Fiddler to capture the requests from JMeter and the real browser, the requests must be exactly the same including:
URL
Headers
Request body
all the dynamic parameters must be properly correlated. Given you will send the same request you should get the same response
i am still new to JMeter and i was assigned to a work that I will need to use JMeter to perform automation testing. The idea is to write script using JMeter and run the script to fill in the forms in the website. I was curious that can JMeter use different data from the database to fill in the form of the website everytime it execute?(unique data for every user)
I have followed this tutorial (https://www.blazemeter.com/blog/fill-forms-and-submit-with-jmeter-made-easy/ ) and it succeed, however, when i try to change the parameter name (to some other names that do not matches the field name found in the inpect mode), it still works. So i was wondering how JMeter knows where to put in the parameter even i have change to a wrong field name?
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).
Browsers don't do any magic, they execute HTTP Requests, wait for response and render it. JMeter in its turn can execute the same HTTP requests so traffic would be the same, however it will not render the response, but rather measure the time and collect some more metrics.
If you change the names of the inputs in the form most probably the request will be successful, to wit you will get HTTP Status Code below 400 hence JMeter will mark the result as "green", however if you inspect the response using View Results Tree listener you will see that the form is not filled and/or you still at the same page.
If you want to use JMeter for checking the data returned by the application you're testing consider using JMeter Assertions to test presence of expected values, absence of errors, set response time thresholds, etc.
You can automate the form submission or order placement usin JMeter. You can JMeter for API testing as well by adding assertions. But the main purpose of the JMeter is to test the performance of the application. Its not like selenium which performs actions on the browser whereas JMeter sends the request in various protocols to relevant server and can also simulate many users at the same time.
If you want to do extensive automation testing,JMeter isnt the ideal tool for that.
You can use webdriver sampler to run the selenium with jmeter. It requires to configure sampler and browser config which are plugin and can be downloaded using plugin manager.
For more info:-https://www.blazemeter.com/blog/jmeter-webdriver-sampler/
Now, without the plugin it is working on protocol level and not on the frontend as pointed out in the above comments.
So, yes it can depend on which layer you want to work. It can work on frontend like selenium using the webdriver plugin and can submit the form with different data as a direct request to the server without using the frontend/GUI.
Hope this helps.
It depends on what you are trying to automate. If you plan to automate API invocation where there are some pre-requisites like grabbing tokens, cookies, session IDs from the browser, then JMeter can probably be used where existing JMeter capabilities can be leveraged using BeanShell scripting and other plugins.
But if you plan to have a full blown UI automation framework then JMeter might not be an ideal choice.
I want to do load test as well as performance test a website and I have recorded user step by step action through jmeter recording by proxy setting. And when I run this recorded test it gets passed all the sections except one section.
During recording steps, it gets filled all the required fields like POST, GET, PATH etc by default as well as like token, session id etc in the HTTP header manager. When user login again its get unique session id and token through Regular Expression Extractor. But my test gets failed when the user wants to accept a task it says unauthorized. I have attached screenshot.
This image showing all the steps user will do from login to logout.
Here steps 2.9 section gets fail.
Here its showing the response from the server.
Please let me know where am I doing wrong.
There are multiple possible issues with your test:
Location of the Regular Expression Extractor and other Post and Pre-Processors. According to JMeter Scoping Rules they are applied to all your Samplers so please double check if this is something you're looking for. If you want to apply the Post-Processor to a single sampler - you need to move it to be a child of the particular sampler
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting so consider converting your Beanshell test elements into JSR223 ones
Since JMeter 3.0 there is JSON Extractor which you should be using instead of the plugins
In general HTTP status 401 means Unauthorized so double check that your test is doing what it is supposed to be doing using View Results Tree listener. You might also want to double check JMeter Variables values using Debug Sampler as it might be the case that the variables are being overwritten with something you don't expect due to the aforementioned Scoping Rules potential issue
Im using Jmeter and do performance testing for my web application. I record my actions in jmeter and play back the same. The testplan got run but when i verify the database manually, the new row is not created. The value got added in the existing line.Please help me out of this. I am struck in this step for 2 days
Verify if your requests includes hardcoded session's data. If your app manages sessions and you just "recorded" the actions, probably you are re-using the same session's data. Assuming there is a login page -> the requests after the login would use a session, usually returned for the login action.
As comments are not enough descriptive; posting a new answer. You can do this by using regular expression extractors, because -probably- the session info comes in the response (so extract it into a variable, by parsing the response with a regex extractor)
and then use the variable in further request/s.
This is a tricky way and need lot of work... even more if the session keep changing in subsequent responses (it usually change while moving worward through the page/app workflow), if that is the case you will need to extract the data after each request.
Please reffer to the jmeter manual for more info about regex extractors.
I am using Jmeter(2.3.2) to create script for one of my application with a scenario which has flow for 4 to 5 pages. I have recorded the script using HTTP Proxy Server. The scripts has been generated successfully under Thread Group >> Recording Controller.
After running the scripts (Threads- 1, Ramp Up period - 1, Loop Count - 1 ), below are the observations I noted in View Results Tree:
The Result Tree view shows all as Checked(Green) - OK
The Sample result for all screens shows Error Count as 0 - OK
But in the response tab when I try to view the results by using 'Render Html' response data - the response data shows the same response for all the requests.
I am getting the response data of the first request for all the other requests.
I am not sure, whether the Jmeter script generated is functional or not? What is the cause for getting the same response data for all the requests?
Please, can anyone let me know what may the issue?
I bet that the same page you're observing is a kind of login page or dashboard which is accessible by unauthenticated user.
First of all make sure that you have HTTP Cookie Manager added to your test plan. It represents browser cookies and deals with user sessions and cookie-based authentication.
If it doesn't resolve your issue the problem is bigger and you will need to do some extra stuff. Modern web applications use multiple mechanisms of current state of things storing and managing, security enhancements and so on. From JMeter's point of view it results in dynamic mandatory parameters. The process of these dynamic parameters extraction from previous request and adding them to next request is called "correlation". So you need to do the following:
Detect which parameters being sent by a recorded script are dynamic. The easiest way is to record the same scenario several times and inspect request bodies to see what is being static and what changes.
Once you figure out which parameters are "interesting" you need to locate them in the first response body/headers/etc.
As soon as you have identified what necessary parameters are and where they live you need to use one of JMeter's PostProcessors to extract required values from previous response and save them to JMeter Variables
Once you have a JMeter Variable it can be used wherever required.
Depending on response data type the most commonly used JMeter's Post Processors which provide correlation capabilities are:
Regular Expression Extractor - the most commonly used test element which covers >90% of needs.
XPath Extractor - better to use against XML data i.e. for testing SOAP Web Services.
CSS/JQuery Extractor - when you need to fetch something from complex HTML where Regular Expression Extractor is useless.
So for putting everything together loog for "jmeter correlation" in your favorite search engine or see ASP.NET Login Testing with JMeter guide.
First JMeter 2.3.2 is WAY TOO OLD (10 years old), upgrade to JMETER 2.11.
Second, Jmeter cannot guess that the response if KO if the returned code is 200, so you need to add Response Assertion that will check for some text you expect in the page.
