How to start with web service testing using jmeter? - jmeter

I am trying to learn web service testing using jmeter.Can anyone tell me how to proceed which samplers and request should i use.How should i practice as I am not having any web service to test.
Thank you

The recommended test element for web service testing is "usual" HTTP Request sampler.
You can get a minimal web service test plan (it includes a web service endpoint by the way) in a couple of clicks like:
JMeter Main Menu -> File -> Templates -> Building a SOAP WebService Test Plan -> Create

Testing REST API provider response without mock

Currently, I am working on a project on Spring Boot where we are integrating with external REST API. As part of our integration suite test, we are doing the mock test of the actual external API which executes as part of the CI/CD.
My question is in production it calls the actual API so, how we can do that in the test environment. I don't think we need to make the actual external provider call during multiple integration test which will load the external API, also at the same time would like to test with actual REST response from the service.
Any suggestions?
If the public API has a swagger description, you could use the Atlassian Pact Swagger Validator. I describe the workflow in this talk: https://www.youtube.com/watch?v=79GKBYSqMIo#t=39m10s
Another alternative would be to create a mock API for the external service. There are some free services like https://mockfirst.com, https://www.mockable.io/, etc. where you can do that.

Can we use Jmeter with Rest Assurred framework?

I need to know if we can implement Jmeter script with the RestAssured framework?
Theoretically yes, given you copy RestAssured .jar file along with dependencies to JMeter Classpath you should be able to use its methods from JSR223 Test Elements or reuse your existing tests via JUnit Request Sampler
However it would be much better to use JMeter's HTTP Request samplers as in this case you will be able to access networking metrics such as Connect Time and Latency, automatic failures on HTTP Status Codes above 399, Cookies, Headers, and Authorization management, etc.

Using JMeter to test a Flex/Spring web app

i have a Flex/Spring web project where the client is a flexapp that runs in the browser and the server components(Spring/Hibernate) runs in tomcat.
The compile dcluient files also obviously reside in the tomcat server.
i want to use JMeter to do some performance testing on the application.
i am new to JMeter and don't know how to connect the JMeter with the application.
From what i understand i cant use the http request based test cases as i am using flex.
Any reference will help.
What kind of plugins do i need on the JMeter instance?
How to configure JMeter to be able to call the application via flex?
You will need a third-party JMeter plugin.

load testing using multithreading for a spring rest ful webservice

I had implemented a restful service. I want to do a load testing for spring rest ful service. In this i want to check how many users can access a service. How to do that..Please provide me some information.
There are a variety of tools out there you can use for load testing. I've found JMeter to be a pretty robust open source option. Specifically for REST requests you can use the HTTP Request component.
That said, I'd be curious to hear what others are using.
