API integration and Development tools to build REST APIs

API Integration and development tools

Introduction

Since most microservices projects employ APIs (Application Programming Interfaces), organizations are shifting to the Microservices Architecture paradigm to thrive in their software product initiatives.

We live in an age where end-users who rely on programs for their needs expect quick outcomes or services. To deliver and receive information, many APIs use REST protocols via HTTP. Many system developers use UI-based tests and API tests to automate their testing. When comparing API testing to UI testing, API tests are significantly faster and more reliable.

An API is a set of software programs and services that can be used to connect and perform other software applications. API testing entails sending calls to the API, receiving output, and logging the sensitivity of the system using the software. API Testing becomes much more crucial in agile development as product innovations become quicker, putting more demand on test automation.

What do you mean by API Testing?

Generally speaking, it serves as a channel between programs, devices, and databases. Let’s pretend you’re looking for a plane ticket on a computerized reservation site. 

  • Within your established costs, it will prompt you to provide the needed details such as origin, destination, and one-way or round-trip journey information.
  • When you tap on search there, APIs come into play, it interacts with each airline’s API and returns suggestions that meet your criteria. 
  • Everything happens within a fraction of time.  Isn’t there no point in using an API if it doesn’t function well in real instances?
  • To avoid these scenarios, API testing is the best option. As a result, we must verify the API prior to allowing the audience to use the application. 

API analysis is a type of software testing that is performed to design APIs in order to ensure that the developed application’s performance, implementation, privacy, and reliability are all met. It primarily focuses on software architecture’s Business Logic. Testing is a critical component of a Seamless Integration & DevOps application’s success.

As of 2020, the most fascinating technology for persons who deal with application programming interfaces (APIs) around the world, a report provided by Statista.

Services to develop your API

  • Amazon Web Services (AWS) Gateway

AWS Free Tier provides you with unlimited access to Amazon API Gateway as well as other integration services. The easy accessibility comes with restrictions, such as a monthly limit of 1 million API calls or 750,000 connection sessions. These figures would be sufficient for the first installation.

  • IBM Cloud API

Despite the fact that IBM Cloud‘s web account only covers a fraction of the services provided, it helps you to get a sense of the product’s capabilities. As a result, you won’t be able to create a comprehensive product interface on it. IBM, on the other hand, offers API Connect, an API administration tool, which is similar to AWS’s capabilities.

Initially, IBM’s API Connect was solely a tool for developing APIs, but it has since expanded to include other tools. These technologies are essential for creating composite API designs, fostering discovery, and interfacing cloud services with enterprise systems, among other things. The free version of IBM Cloud allows for 50,000 API requests per month.

  • The gateway service should be started.
  • The “Managed APIs” page appears when the gateway is opened.
  • Select the title of the API you need to investigate on the “Managed APIs” page.
  • Hit Review and test in the navigation menu.
  • TestNG

JUnit and NUnit for the Java language influenced TestNG. The major goal is to give simple functionalities and to complete all types of verification processes, such as unit, integrating, and functionality testing.

  • By combining TestNG and Selenium, we can get a quick report that tells us how many test cases failed, advanced, or returned.
  • Connect easily with DevOps tools like Maven, Jasper, Docker, and others.
  • Indications in TestNG make the code easier to read, and exceptions are captured more efficiently than in JUnit.
  • TestNG can be used to develop data-driven tests.
  • Runscope

Runscope is an API tracking tool that ensures APIs are functioning properly, delivering accurate data, and are debuggable. You can integrate the Swagger 2.0 API specification standard (in JSON format) as well as other common diagnostic formats into Runscope. This also applies to Runscope’s standardized format for testing its services. Because there is no free edition of Runscope, you must opt for the 14-day free trial, which can be selected from any of their pricing options.
