Which tool is used for API testing
Application Programming Interface (API) acts like a messenger between two software units or two applications so that data can be shared and collaborated. API testing tools bring a sort of technical finesse to the execution process. These tools ensure an efficient, reliable, secure and robust API execution. API testing tools enhance the efficiency of the API testing process, thereby saving time and costs and also increasing the speed of execution. In this article, you will get to know some of the best API testing tools.
What is Application Programming Interface (API)?
It acts as a middle layer between the database and the user interface. Data is communicated and exchanged from one software system to another.
What is API testing?
It is a software testing practice that tests for security, performance and functionality. The application logic is tested using the API testing method. It is an effective testing method that consumes less time for implementation.
Bottlenecks or security hassles are identified in the APIs prior to the execution process. Calls are sent to the API, the output is gathered and a proper log is maintained.
Following are some of the popular API testing tools:
1. Postman: This tool includes a set of tools to quicken the API lifecycle, starting from testing, design, documentation and sharing of APIs. APIs are tested with the help of Postman API client with the definition of complicated API requests for HTTP, SOAP, REST etc. An enriched experience is provided by its easy-to-use REST client. It is accessible for both automated and exploratory testing. It provides third-party support for RAML formats, Swagger etc.
2. SoapUI: It is one of the most popular API testing tools that test HTTP-based services and web services — SOAP APIs and REST. It is an open-source tool that comes with both a fixed and free package. Comprehensive tests can be created, managed and implemented through SoapUI in an easier and faster manner. It offers data-driven testing, API security, API performance testing, API functional testing and test reporting.
3. Assertible: It is an easy-to-use API testing tool that helps in monitoring web services. Even after deployment, it supports API test execution. Automatic QA tools are offered for supervising and testing web services around different environments and deployments. QA pipeline is automated for faster coding and noticing crashes. HTTP responses are provided with the required support.
4 Rest-assured: This tool can work by using languages like Ruby and Groovy in the Java domain. This open-source tool can be leveraged for verification and validation of the response to requests. REST APIs are tested with the help of Java libraries and then they can be seamlessly integrated with Maven. Fetching of data can be done from the requests and responses, despite complicated JSON structures. Core Java fundamentals can be used for simplistic implementation. Effective and simple automation testing of APIs can take place.
5. Karate DSL: This open-source tool combines UI automation, performance testing and API test automation and mocks into an integrated, distinct framework. It offers a simple, readable syntax that is designed for JSON, HTTP, XML and GraphQL. If automation capabilities are being integrated with data assertion competencies then a Java API can be used. Tests can be easily written by non-programmers.
6. vREST: This API testing tool offers an online solution for automated testing. Test suites are created with test data, record/replay functionalities and specifications, thereby making the least use of QA resources. It can easily integrate with CI/CD tools and provides seamless data-driven testing. It has a strong response authorization and provides faster validation of REST APIs. With the help of efficient API automation techniques, time is saved to a great extent.
Conclusion: If you are looking forward to implementing usability testing for your specific project, then do get connected with a professionally acclaimed software testing services company that will provide you with a methodical testing roadmap that is in line with your project specific requirements.
