Introduction: What is an API and why is it important?

An API is the interface that connects two applications, such as a web application and a database. It is an integral part of software development. An API can be used to connect to various databases and other types of services, which makes it an important tool for programmers. It ensures that data is clean and accessible for other applications.

5 reasons why developers need to care about API testing

• API testing is a critical part of the overall software development process.
• APIs are an increasingly important part of how software systems work, and how they interact with customers and other systems.
• Developers need to be able to test the APIs that they create in order to ensure that they are working as expected and that they can handle any load that might be put on them by other developers or customers.
• API testing can help developers identify and fix bugs before deploying new releases, which reduces the risk of releasing broken code to production and saves time in the long run.
• API testing is a key component of security testing, which helps developers find vulnerabilities and protect their customers from data breaches or other security incidents caused by software bugs.

How they work

API tests, also known as web service tests, are the most common type of automated tests. They are used to ensure that a web service is working correctly and can be accessed by other applications.

Api testing framework is a software that offers a set of tools for performing API tests. It provides you with an easy-to-use interface for creating and running test cases without the need to write any code or learn a programming language.

The following are some of the most popular api testing frameworks:

• Postman
• SoapUI - REST Assured

Example of an API test using Postman

                	
                      POST /hello/world HTTP/1.1
                      Host: api-server.com
                      Content-Type: application/json
                      Content-Length: 12
                      { "company": "Techverse" }
