Introduction
Functional tests by Ready API ensure that an API or web service adheres to the necessary business logic. A test usually consists of sending requests and determining whether the answers match the expectations. Functional tests concentrate on what the service does, so it is not necessary to look at how it operates.

This blog explains the details of Samples for Functional Testing in ready API and the details of Creating Your Function Test, Explore Test Project, Modify Test Project, and Run Functional Tests.
Creating Your First Functional Test
You can quickly carry out functional, performance, and security testing of web services with Ready API. You can create a local virtual copy to conduct your tests before the real service goes live.
The creation of fundamental functional tests using Ready API is covered in this tutorial. A web service definition will be loaded from a file, a test for one operation will be written, run, and assertions will be used to confirm the test results.
Basic Concepts
You must understand basic testing principles and web service technologies to create and run tests using Ready API. These subjects are extensive and outside the scope of the Ready API documentation. We've put together a high-level overview to make it easier for you to start with Ready API.
🔥 Terms
🍀 In client-server applications known as web services, clients and servers communicate over the Internet using the HTTP protocol or another protocol based on HTTP. These applications include, for instance, online banking services, weather monitoring systems, and navigational software.
🍀 The URLs to which clients send requests include details about the tested server (host), the communication port, and the requested server resource, such as a page or file path.
🍀 Requests that clients send to servers have the following structure:
🚀 The starting line with the message and response code. Common error codes include 404 Not Found and 200 OK (success) (failure, the requested resource was not found).
🚀 Headers specify the response data format and include extra values like cookies, server information, and so on.
🚀 Response body, for instance, an array with requested data, an image, a file, and so on.
🚀 JSON and XML are frequently used formats for request and response bodies.
🚀 Depending on the service architectural style, the command that a client send to the server for execution is referred to as an action, method, or operation (SOAP or REST, see below).
🚀 SOAP and REST are the two most widely used architectural types for web Services.
🔥 How You Can Test a Web Service
🍀 You develop and execute functional tests on a web service to make sure it operates Correctly.
These tests send requests to the server and verify its responses.In Ready API, the Functional Tests node is where you create functional tests. In specialized editors, it is simple to simulate requests and modify their parameters:
You add assertions to test requests to verify response data and response codes.Checking the response code is the simplest way to determine whether the server is functioning properly. 200 OK typically indicates that the server successfully handled a request.
🍀 A client typically makes some requests to the server in real life. For an online store, for instance, the first request might be for logging in, and the following might be for making purchases.
By grouping requests and other test steps into test cases in Ready API, you can simulate this real-life behavior.
🔥 Requirements
A WSDL definition of the SOAP service is required to test it in Ready API. This definition explains how the service operates and how requests and responses are formatted. Ready API uses this data to simulate requests.
Definitions may also be used for REST services. The most popular definition formats include WADL, Open API, and others. These definitions can be loaded into Ready API so that test cases based on the information in them can be made.
