Best tools to create Restful API

The Software Testing Trends for 2018 indicated that APIs (Application Program Interface) are important to successful digital transformation and there is an increasing demand for API testing at a greater level of automation. Application Programming Interfaces testing is a type of software testing where testing cannot be done at a front-end since there’s no GUI. API testing has mainly performed the testing on the message layer and includes testing REST API, SOAP Web services, which could be sent over HTTP, HTTPS, JMS, and MQ. Many companies nowadays require strong API performance and shift towards APIs architecture. However, the main utilization of test automation now focuses on UI while most API testing is carried out manually. Therefore, the testers need to equip with intelligent and easy-to-use automation tools to test APIs, helping to reduce time-to-market and improving testing effectiveness and productivity. There are lots of tools available for API testing, but how do you choose?

The following are the top restful API testing tools that we believe can help you, with descriptions that might guide you in choosing one over the other - though they're all great options. This tools will help you to get your work done more quickly and with greater effectiveness.

So, let's see the list -

PostMan

One of the most popular HTTP clients is Postman. It has a very beautiful GUI interface and very easy to use regardless if you're just starting out with RESTful APIs or an expert. A history of past calls is stored so you can quickly reissue it. Postman even includes some nice touches such as auto-completing standard HTTP headers and supporting and rendering a variety of payloads from JSON, to HTML, to even multipart.

Karate DSL

Karate DSL, which is pretty new, makes creating scenarios for API-based BDD tests really simple since unlike most BDD frameworks (Cucumber, JBehave, SpecFlow), you don’t need to write step definitions. The reason for that is that Karate has already created all the step definitions you need in order to get started testing APIs.

HttpMaster

HttpMaster will be a right choice if you are looking for a tool that helps in Website testing as well as API testing. Other features include an ability to define global parameters, provides the user with an ability to create checks for data response validation by using the large set of validation types that it supports.

Fiddler

A fiddler is a tool that allows you to monitor, manipulate, and reuse HTTP requests. Fiddler does many things that allow you to debug website issues, and with one of its many extensions, you can accomplish even more. For more hardcore API testing development, you can use the FiddlerCore.NET Class Library to build your API testing infrastructure.

Katalon Studio

Katalon Studio is a free automation test tool that provides a common environment to create and execute UI functional, API/Web services, and mobile testing. The capability to combine UI and Business levels (API/Web services) for different environments (Windows, Mac OS, Linux) has been considered an advantage of Katalon Studio.

Chakram

This tool supports end-to-end test on JSON REST endpoints. This tool also supports third-party API testing. This tool can be a great help if you are looking for testing API’s that are still under development. This is built on the Mocha testing framework.

Rest Console

HTTP Client and Request Visualizer and Constructor tool, helps developers build, debug and test RESTful APIs. Rest Console is an HTTP Request Visualizer and Constructor tool, helps developers build, debug and test RESTful APIs.

SoapUI

SoapUI is a fully functional test tool dedicated to API testing. Rather than having to create a solution from scratch, API allows you to leverage a tool full of functionality aimed strictly at API testing. SoapUI has been around for a while now. If your teams are doing API testing only, it might be the best choice. If for some reason you need to create a custom workflow or functionality, you can code up your solution in SoapUI using Groovy.

WebInject

WebInject is a free tool used for testing web applications and web services. This is written in Perl language and for running this on any platform, a Perl Interpreter is required. This tool uses an XML API for creating test cases and generates HTML and XML report which includes pass/fail status, errors, and response times. Overall it’s a good tool.

Parasoft

Parasoft, an API Testing tool helps in automated test case generation which can be reused and easily maintained and thus reduces a lot of regression effort. It supports end-to-end testing and has a very user-friendly interface. Also supports multiple platforms like Java, C, C++, or.NET. This is one of the top recommended tools for API testing.

Rest-Assured

Rest-Assured is an open-source Java Domain-specific language (DSL) that makes testing REST service simple. It simplifies things by eliminating the need to use boilerplate code to test and validate complex responses. It also supports XML and JSON Request/Responses.

Runscope

An excellent tool for monitoring and testing API’s. This tool can be used for data validation of API’s to ensure correct data are returned. This tool comes with a feature of tracking and notifying in the case of any API transaction Failure, Hence if your application requires payment validation, then this tool can prove to be a good choice.

Apigee

It’s a complete API Management tool that lets user measure and test API performance supports building API using several other API editors like Swagger. This tool also extends to ensure API’s remains secured and it protects from OWASP top 10 threats like SQL injection, XSS etc. Also, provides excellent analytics feature.

JMeter

JMeter includes all the functionality you need to test an API, plus some extra features that can be taken advantage of to enhance your API testing efforts. For example, JMeter can automatically work with CSV files, which allows your teams to quickly create unique parameter values for your API tests. It also integrates with Jenkins, which means you can include your API tests in your CI pipelines.
