Introduction
This blog will discuss the webservices test plan in JMeter and how we can write a webservices test plan in Jmeter step by step. JMeter is an open-source testing software developed by Apache based on pure java programming. JMeter is used to measure and observe the performance, functional, and load testing of web applications created in java.
We will learn how to create a webservices test plan in JMeter to perform the relevant testing for our application.
Webservice Test Plan

Before we get into the webservices test plan, we should be familiar with a few terms like what is web service and API so that we can have a better understanding of the article.
Webservice is a standardized way that guides the machines to communicate with each other over the internet. For example, client and server interaction can be an excellent example of a webservice. XML is the language that is widely used to create webservices.
We should also know about APIs and types of web APIs. An API is an application programmable interface that uses a medium to transmit information or data between the client and server to make communication possible.
Two types of web API are widely used to communicate over the internet.
We will use the REST API method to demonstrate the webservices test plan.
For testing purposes and to demonstrate REST API methods, we will use APIs already available to us over the internet.
We will use the studio ghibli API to demonstrate the webservices test plan. You can use any REST API you want, which is legal and publicly available or create one yourself.
