How to import webservices in Jmeter - jmeter

I'm trying to import the webservices that are in the WSDL into Jmeter using SOAP/XML-RPC request. But I didn't see anything with the 'Import' or LoadWSDL option. I saw this video https://www.youtube.com/watch?v=IsmrHK6FPjA which has the webservice(SOAP) request which I cant see it in my Jmeter version.
The reason I'm asking is because in each SOAP/XML-RPC Data, I've to open SOAPUI to get blank request and then paste it in the Jmter. We have hundreds of webservices to test and this method is getting very lengthy process.
Is there a way in Jmeter to create blank requests like SOAP UI if I give the wsdl URL and it generates all possible requests for us. Thanks in advance.

There is no such import feature in JMeter.
But a way to do it is to put JMeter as a proxy for SOAP UI using HTTP Test Script Recorder, then you would avoid Copy/paste thing.
Read also this for up to date way of testing webservices:
http://jmeter.apache.org/usermanual/build-ws-test-plan.html

As per the jmeter latest version help WebService(SOAP) Request sampler is DEPRECATED. This sampler is having load WSDL option. Try older version of jmeter..

Can JMeter do automation testing like Selenium can do?

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.

Performance - how to capture all the Request in the Network tab of chrome in an automated way

I am in a process to capture all the request when an HTML page is loaded. My end goal is to create a report with the time taken for each individual request and also for the total time taken to load the entire page. I have tried to use the performance.getEntries() but it is limited to store only 150 request in the buffer. To overcome this I tried to set the performance.setResourceTimingBufferSize(size) but this buffer size is reset to default 150 when i refresh the page.
I would like to know the solution for below few things,
how to set the performance.setResourceTimingBufferSize(size) before loading any page (if I set it when the page is loading it misses to capture some of the request). Few suggested to set this in HTML head tag, but this is not possible in my case because i need to use selenium and i cant modify anything in source file.
I also found that we can save all the request as HAR file in chrome console. is there any way to do it in automated way?
Is there any other way to capture all the request ?
PS: I a using Jmeter (to simulate multiple users) to run the selenium scripts using web driver sampler. The automated way in the sense it should be done using selenium.
You can use BrowserMob proxy in order to create and start a proxy server which will capture data and save it in form of .har
Download BrowserMob proxy and put .jar files somewhere into JMeter Classpath
Restart JMeter to pick the .jars put
In setUp Thread Group add JSR223 Sampler and put the following code into "Script" area
import net.lightbody.bmp.BrowserMobProxy
import net.lightbody.bmp.BrowserMobProxyServer
import net.lightbody.bmp.proxy.CaptureType
def proxy = new BrowserMobProxyServer()
def captureTypes = new HashSet<>();
captureTypes.addAll(CaptureType.getAllContentCaptureTypes());
captureTypes.addAll(CaptureType.getHeaderCaptureTypes());
captureTypes.addAll(CaptureType.getCookieCaptureTypes());
proxy.setHarCaptureTypes(captureTypes);
proxy.start(8080)
proxy.newHar()
props.put('proxy', proxy)
Set up your Chrome Driver Config to use proxy from the step 3
Add tearDown Thread Group to your Test Plan and in another JSR223 Sampler use the following code to store requests made by the WebDriver Sampler(s) into a .har file:
def proxy = props.get('proxy')
proxy.getHar().writeTo(new File('some.har'))
proxy.stop()
That's it, now you should have .har file generated during test execution.

BrowserMob Proxy: Embedded Mode
Apache Groovy - Why and How You Should Use It
For your goal, you can try https://gtmetrix.com/. This will give you a report for the load time and all the requests in waterfall model like in browser. Moreover, you can download the full report in pdf and can do compare and retest.
There you can also download the HAR file.
Though, it is not related to selenium but may fit your goal and It can be automated.

How to make ajax calls by using jmeter?

I have a game website to do the load testing, but I need to do load testing of scoreboard, which is an Ajax call and changes dynamically.
I have tried to do this by using Groovy language and jsr223 sampler, but it's not working. Then I tried using the web driver sampler. I am unable to do it in both cases.
By using the web driver, a new browser gets launched every time and it's unable to do load testing by simulating 100 or more users.
Is there any way to do this?
Please take an help from below:

Randomizing http request path in Jmeter

Currently my jmeter tests have a few GET http requests. In the request, i've got data filled in the "path" field.
I'm looking for a way to randomize Jmeter so it will call an array of "paths", however i can't seem to figure this out. Anyone have any tips?
thanks!
JMeter's test element most commonly used for parametrization and data-driven testing is CSV Data Set Config
There are built-in JMeter Functions which can be used to get data from external sources
__StringFromFile
__CSVRead
There is a chooseRandom function available via JMeter Plugins

jmeter regarding performance and load testing

Let me describe the issue which i have been facing.
i want to do performance and load testing on our internal website. which has login and other functionalities.
the issue i am facing that when i hit 12 or any number of request using http sampler then i am getting same response from all the 12 request. But actual scenario is that webpage displays different data for different page.
I checked using firebug and everything is working fine over there using correct response from request but when i use jmeter i am using same response from every request.
Please let me know if anybody had faced same kind of issue of is there anything i am doing wrong in configuring script.
Try to add HTTP Cookie Manager to your test-plan to the root (Test Plan) node or to the Thread Group node.
As per jmeter documentation:
The last element is a HTTP Cookie Manager. A Cookie Manager should be
added to all web tests - otherwise JMeter will ignore cookies. By
adding it at the Thread Group level, we ensure that all HTTP requests
will share the same cookies.
Ensure that parameters values that are dynamic are not hard-coded (after recording jmeter scripts, for example): no hard-coded JSessionID values in your HTTP requests, e.g..
Ensure you don't miss any necessary params in your HTTP requests.
JMeter does not process Javascript or applets embedded in HTML pages.
Your problem may be caused by this feature.
As per jmeter documentation:
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.
I would also recommend your to look first into Jmeter reference before further scripting activities - this may prevent from some faults and frustration.
At least these:
Building a Test Plan
Elements of a Test Plan
Building a Web Test Plan
Building an Advanced Web Test Plan
Hope this helps.
I would suggest - Use Jmeter's Regular Expressions. You may be able to resolve this issue with RegEx. Post using regex, use 'View Results Tree' listener to check if you are getting apt response for each of your threads.
You can also analyze your results using Blazemeter's listener that gives you more insights into your test.
