In this issue, the editor will bring you what are the tools for building and testing API. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

Immediately build API like a professional

Organizations are changing the micro-service architecture model that they have succeeded in software application projects, which is why most micro-service projects use API (application program interface). We should applaud the micro-service because it has a variety of advanced features compared to other models.

Similarly, these datastores have separate commands to process each datastore; in addition, it allows software providers to deploy components faster. If one application is updated, the remaining applications do not need to be updated; they can continue their functionality.

We are in the process of providing quick results or services to end users who use applications to meet their needs. Many API use REST services to send and receive data through HTTP. Many software testers use UI-based testing and API test automation testing. When comparing API tests with UI-based tests, API tests are much faster and more reliable than UI-based tests.

What is an API test

Before we go any further into API testing, we need to know what API is.

In general, it acts as a messenger for applications, devices, and databases. Suppose you find flights through an online travel booking page. It will require you to enter the necessary details, such as departure, destination, and one-way or round-trip route information within your price setting.

Once you click on the "search here" API, it will interact with each airline's API and provide results that meet your specifications. It all happened in a matter of seconds.

If API does not work properly in a real-time scene, then API will not be used, right?

To avoid those scenarios, we need to choose the API test. So before users can use this service, we have to test API.

The necessary API testing is a kind of software testing that enables the developed API to build the function, execution, security and reliability of the application. It focuses on the business layer of software architecture. Testing is a key part of the success of Continuous Integration and DevOps applications. TestNG was inspired by JUnit and NUnit in the Java language.

Let's take a look at how the following tools simplify our development tasks.

1. SoapUI

SoapUI is a well-known testing tool for testing web service API. It can check both SOAP Web service and RESULTful Web Service. SoapUI can be used as an open source and PRO version, but you can guess that the PRO version has additional features. It is based on Java, so it is suitable for most operating systems. The most important thing is that it is easy to learn and use, and reliable for all users. Trusted by millions of users, you can use them for a variety of test cases.

Functional testing

Data-driven testing

Simulation test

Safety testing

Performance testing

2. Katalon Studio

Katalon Studio is an automated testing tool for WEB, API and mobile. It is considered as a new testing tool and a leader in the field of automation.

Important features:

End-to-end testing solutions for developers and testers

Support all SOAP and REST requests

Use frameworks such as BDD Cucumber. This is a testing method in which written test cases are in natural language and facilitate the transmission between business stakeholders and technical human resources.

Built-in integration with Jenkins,JIRA,Slack,Docker and qTest

Make effective use of Katalon UI / UX functions, such as search, drag and drop, built-in keywords, select test cases

You can use the free version of Katalon.

3.TestNG

TestNG is inspired by JUnit and NUnit for the Java language. Its main motto is to provide easy-to-use features and to meet all types of testing phases, such as units, integration, functionality, etc.

By using TestNG with Selenium, you can create a prompt report where we can see how many test cases failed, progressed, and returned.

Easy integration with DevOps tools such as Maven,Jenkins,Docker.

Using comments in TestNG improves the understandability of your code and makes it easier to catch exceptions automatically than JUnit.

You can use TestNG to create data-driven tests.

4.Postman

Postman is a tool that can perform build and test API. It is open source and easy to install. Postman workspace has new functions, import function, run function, workspace, invitation, collection, request tab, HTTP request and save function.

Key points:

Use JavaScript to write and run tests for each request

When testing API in Postman, you can choose the HTTP method you want, such as GET,PUT,POST, and so on.

You can use the manage Environment feature in Postman to provide input values for any API result.

Stores the associated endpoint in the collection.

Postman has many advantages for building API faster. If you are interested in hands-on, please check out this Udemy course.

5.Swagger

Swagger, which is the best AKA API tool for designing, building and testing API. Swagger tools are both open source and professional tools that help millions of developers and testers provide excellent API.

Properties:

Inspector is easy to design, record, and test API

You can also test API on the cloud

Support all types of services such as REST,SOAP

SwaggerHub is a platform that you can use OpenAPI to design and document

6.JMeter

JMeter is a simple and powerful automated testing tool. You can use JMeter scripts to perform performance tests of RESTFul services in different languages, such as Java,JavaScript and PHP. It was designed to test Web applications, and has since been extended to other testing capabilities.

Features:

JMeter is a fast API testing tool because it can quickly perform range testing

Open source and support the installation of a large number of plug-ins and extensions

JMeter has a separate function to add parameters in the parameters tab, which we can't find in other programs.

Perfect functional and load testing can be performed in JMeter

7.Rest Assured

The RestAssured library is an API tool tailored to the Java domain that uses people to test and verify REST services. It is also used to test Web services based on HTTP,JSON and XML, and it provides us with many key functions, such as XPath validation, JSON path syntax, simple file upload and specification reuse. And it is mainly influenced by dynamic languages such as Groovy,Ruby.

One of the great features provided by Rest Assured is that after you get the answer, you don't have to parse the XML or JSON response.

8.Tricentis Tosca

Tricenti Tosca is a custom continuous testing tool for the DevOps platform because some of the major tools do not meet the requirements in the DevOps environment. Beginners can also understand Tosca tools and can immediately create advanced API tests from a business perspective and then integrate them into all scenarios.

Tricentis Tosca is suitable for continuous testing and automated testing based on mobile devices, Web,UI,SAP, etc.

9.Apiary

Apiary is a complete API platform where we can design, build, develop and document API. It provides a framework for faster development, testing, and implementation of production-ready API. In general, to create an API, you need to define patterns for inputs and outputs, which can be designed as simulations in Apiary API.

This simulated API will meet the application specification without changing any coding, while integrating and testing data. Building an API has different workflow stages. However, apiary can provide independent work for each stage of the team.

10.MuleSoft API

MuleSoft API, also known as AnyPoint API Manager, is a platform on which developers can build, design, manage and distribute API. It enables organizations to integrate with popular cloud services such as Salesforce,SAP. The AnyPoint platform uses Mule as the runtime engine.

API Manager ensures that every API is secure, which is simply complete lifecycle API management.

11.Apigee

Google Cloud's Apigee enables API administrators to design, protect, publish, analyze, monitor and profit from API. It can run in a hybrid cloud environment to perform digital acceleration. Apigee enables regular developers to become API experts.

Apigee edge creates API agents and uses them; you can get real analysis data. Agents created by Apigee edge manage security and authentication to provide better service.

Conclusion: in any case, all API tools can access the same functionality, but in different ways. The best way to experience them is to try to understand which approach best suits your business needs. These are the tools for building and testing API shared by the editor. If you happen to have similar doubts, please refer to the above analysis to understand.
