7 API Testing Tools You Can't Live Without In 2023

API testing is usually performed on the message layer and usually includes testing SOAP Web services, REST APIs, which could be sent over JMS, HTTP and HTTPS. Due to the functionality and technicalities involved in API testing, it is considered to be best-suited by strategic usage of API testing tools. When compared to the other types of testing, the ROI of API testing is considered to be higher. But, again it also depends upon the scope and requirements of the project and other aspects of software testing. To leverage the API testing process, the tactical usage of API testing tools are considered. In this article, you will get to know about the 7 API testing tools that can be considered in 2023.

What is API testing?

API stands for Application Programming Interface and it acts as a communication intermediary between two applications. Two applications talk to each other and the required actions are performed efficiently. A set of guidelines and rules are contained in the API based on which applications are developed.

API testing is a software testing method that focuses on the performance, reliability and functionality of Application Programming Interfaces (APIs). It acts as a bridge between various software systems thereby allowing them to exchange and communicate data with each other.

Following are the seven API testing tools:

1. Apigee: it is a cross-cloud API testing tool that helps users to test and measure API support, performance and also helps in developing API. Apigee also provides PII, SOC2, HIPAA and PCI for apps. It is designed to implement, monitor and extend API. Performance issues are defined by tracking error rate, API traffic and response time. An API proxy can be easily created based on open API specifications.

2. Assertible: It is an API testing tool that focuses on reliability and automation. API tests are automated throughout CI/CD pipeline. It helps in running API tests after deployments and can also easily integrate with familiar tools such as Zapier, Slack and GitHub. HTTP responses can be validated with turn-key assertions.

3. SoapUI: It allows users to test SOAP APIs and REST. The full source code can be acquired and the preferred features can be built. Tests can be effortlessly created with point-and-click and drag and drop. Security scans and load tests can be reused for functional test cases with reusability of scripts feature.

4. Karate DSL: Scenarios for API-based BDD tests can be created by users using this API testing tool without the need to write definition steps. These definitions are created by KarateDSL itself. Reports can be tested and generated likewise to any standard Java project. Multithreaded parallel execution and configuration switching/staging is also supported by this tool.

5. API Fortress: Functional tests can be easily created and automated by developers and testers as API Fortress offers a continuous platform for API testing. It provides easy-to-use intuitive UI. For continuous API testing continuous plug-and-play is simulated. It supports Microservices, GraphQL, SOAP, Test REST and Web Services.

6. Pyresttest: This tool is used for testing RESTful APIs. It is also called as a Micro-benchmarking tool. JSON config files are supported by this tool. Exit codes are returned for failed results. Test scenarios can be built with extract/generate/validates mechanisms. It has minimal dependencies and can also be easily deployed on the server. No code is required.

7. Postman: This is one of the popular API testing tools and is divided into three parts namely Workspaces, Collections and Built-in tools. This tool lets a user to run requests, debug and test, document, create automated tests and monitor API.

Conclusion: The above mentioned are the seven API testing tools. If you are looking forward to conducting API testing for your software product or application, then do visit online a leading software testing services company that will provide you with comprehensive methodology in order to implement API testing successfully.
