How To Choose Right API Testing Solution For Your Business?

Cloud applications and interconnected platforms have become increasingly dependent on API testing. Most of the services we use regularly are interlinked, so if one API malfunctions, the entire service could be compromised.

While working on a project, the developers must conduct API tests to ensure that the APIs perform according to the expectations. It is true that there are several testing tools available on the market that can be used for API testing, but how can a person determine which tools are the best?

The purpose of our blog is to provide you with some of the leading factors to consider before deciding on API testing tools that will accelerate your task and work.

What Is API Testing?

API testing is a process that enables developers to determine if the API used in the project can satisfy the requirements related to the application's functionality, reliability, performance, and safety. After the logic is developed, relevant tests can be designed to ensure that the data is accurate.

The purpose of the API testing service is to find errors, inconsistencies, and differences between what is expected and what is actually happening. This is done both by testing the API components individually as well as testing them as a part of the integration testing between the various software components.

Apps commonly have three main layers - presentation, business, and database layer- and API testing usually happens in the middle business layer between the presentation and database layer. In this case, all transactions interact between the two layers of the business logic administration.

Proper data exchange is made possible with its facilitation of communication between software units. It also confirms the logic of the designed architecture. In addition to validation and functional testing, there are also UI and security testing, fuzz testing, load testing, penetration testing, runtime, and error detection types of API testing.

●??????Extensibility framework for custom applications

●??????Automated assertions and validations

●??????Testing based on data is called data-driven testing

●??????Verify reusability

●??????Fast creation of tests before a service launch

●??????Confirmation of authenticity

2. Efficient Workflows

API testing tools should have the capability of improving workflows.

Having sophisticated methods that simplify test generation, message flow, data manipulation, and integrating API testing into your existing requirements process will make your API testing solution a breeze to use.

To make your life easier, your API testing tool should include the following workflows:

●??????In-depth testing of logic flows

●??????Creating tests with AI

●??????Data management and production

●??????Event observation

●??????BDD (Cucumber) support

3. Supported technologies

You cannot be effective with a tool that does not support all the necessary formats and industry-specific messaging protocols. Your tool must support technologies from the past, present, and future when considering modernization across all industries. Here are some excellent places to start:

●??????REST API testing

●??????Evaluation of SOAP APIs

●??????MQ/JMS testing

●??????Testing of Microservices and IoT

●??????Database Testing

●??????Internet Testing

●??????Analyzing Performance

●??????Support EDI, FIX, and other non-standard communication formats

4. Automation

Automating your API testing process is a vital part of the API testing solution. As part of the automation process, you can run your library of test cases as part of your nightly process or on an as-needed basis, according to your requirements.

To run your API tests programmatically or as part of your continuous integration/delivery process, you should choose an API testing solution that includes both a command-line interface and APIs.

To be successful, you must have the following capabilities and integrations:

●??????Integrating CI

●??????Add plugins to the system

●??????Command-line execution

●??????Open API integration for DevOps

5. Management and maintenance

When you've accumulated a large number of test cases, managing and maintaining them can be a burden. As part of your API testing solution, there should be techniques for determining which API tests you have access to, as well as how you can determine what requirements they are based on.

In order to validate new applications in a wide range of settings and to get comprehensive test results reports that can be shared across multiple stakeholders, you should be able to organize your test case library into a meaningful configuration.

Last but not least, you should choose an API testing solution that offers a change management feature to allow you to version projects and determine the impact of application changes on API test projects. With long-term management and maintenance features like those below, your API testing solution will have a lower total cost of ownership:

●??????Requirements management integration

●??????There are two types of reporting: basic and advanced

●??????Test orchestration

●??????Change management method

●??????Access via browser or on-premises.

6. CI/CD Integration

DevOps teams are continuously deploying software through the application pipeline based on the Agile methodology and continuous integration. This CI/CD pipeline and workflow should be able to integrate seamlessly with API testing tools to keep up with this software development paradigm.

7. A reliable coverage of tests

To accommodate a broad range of API coverages, API testing tools should be robust, flexible, and expansive. It is expected that this application will allow QA teams to build test cases that include both functional testing for non-functional requirements, as well as security, performance, and usability tests for an app.

As a result of its reliability, testers should be able to place their trust in their automated testing units and test suites. In addition to defining the scope of test coverage, API testing tools should be systematic in facilitating test completion and effectiveness.

8. Optimized workflows

It's important for a good API test tool to support a wide range of testing environments, operating systems, scripting languages, and web browsers to make the process of executing workflows as easy as possible.

API Testing Tools: Why Should You Consider Them For API Testing?

As part of an API test, developers have the option of either writing their own framework or choosing from a variety of ready-to-use API test tools available to them. When developers design an API test framework, they are able to customize the test to their liking since they are not limited to the capabilities of a particular tool and its plugins.

It means that testers can include whatever libraries they find suitable for the platforms they are using, build their own reporting standards, integrate complicated logic into the tests, and configure complex scenarios according to their own needs. However, if testers want to develop their own frameworks, they will need to possess sophisticated coding skills to do so.

Conversely, API testing tools provide easy-to-use interfaces and require minimal coding knowledge, which makes it possible for developers with less experience to easily deploy the tests using API testing tools. Sadly, the tools are often designed only for general API testing. And the problems that pertain specifically to the tester's API can go unnoticed because they are designed for general API analysis.

API testing tools are available in a wide variety of subscription and open-source formats. Here are?some examples of the best API testing tools in the market today:

●??????SoapUI

●??????Apache JMeter

●??????Apigee

●??????REST Assured

●??????Swagger UI

●??????Postman

●??????Katalon
