<p>Karate and Postman are automated API testing tools, with different purposes and features. Karate is an Open Source, test-automation framework designed especially for automated API testing. It couples API test automation, mocks, performance testing, and even UI automation into a single, unified framework.</p>



<p>On the other hand, Postman is a widely used API testing and collaboration platform through which one can create, test, and document APIs with an intuitive interface. It allows automated testing supported via its scripting features, giving the ability to easily share API requests among teams much more quickly with responses attached.</p>



<p>However, they have certain limitations as well. Karate has a steeper learning curve for beginners, mainly because of the Gherkin syntax. Postman does very well in manual and semiautomated testing, but scaling it towards testing extensive automated test suites might be tricky.</p>



<p>In this article, let&#8217;s discuss the differences between these <a href="https://testsigma.com/api-testing-tools" target="_blank" rel="noreferrer noopener"><strong>API testing tools</strong></a> &#8211; Karate vs Postman. We will discuss the key differences, features, similarities, limitations, and the best alternatives to these tools as well.</p>

<h2 id="h-karate-vs-postman-overview"><span id="Karate_vs_Postman_8211_Overview">Karate vs Postman &#8211; Overview</span></h2>



<p>Among API testing tools, the two most talked-about are Karate and Postman, but they have many distinguishing features and different capabilities. Knowing the unique advantages and some possible disadvantages of the tools helps the teams understand which tool suits their testing requirements.</p>



<h3 id="h-which-is-karate"><span id="Which_is_Karatenbsp">Which is Karate?&nbsp;</span></h3>



<p>Karate is a compelling open-source framework developed for automated testing, with an explicit focus on APIs. It brings the ability to combine <a href="https://testsigma.com/automated-api-testing" target="_blank" rel="noreferrer noopener"><strong>automated testing in APIs</strong></a>, mocks, performance testing, and UI automation into a unified framework. Tests in Karate are written in a very readable Gherkin syntax, making them approachable to non-developers. It integrates well with CI/CD pipelines, so tests can run and deploy automatically. It also has in-built support of the GraphQL and SOAP API for an extensive scope in a testing scenario.</p>



<h3 id="h-what-is-postman"><span id="What_is_Postman">What is Postman?</span></h3>



<p>Postman is a platform for creating and testing APIs, with an inbuilt user interface. Postman supports automation testing by enabling the scripting of detailed and reusable scenarios of tests. It has a user-friendly interface in which a team can share and manage the requests and responses of its APIs, providing grounds for collaboration among the developers and testers. It also includes API monitoring, mock servers, and environment management features. But for extensive automation and integration with CI/CD, you may need an extra suite of tools or manual, tailor-made scripts.</p>

<h2 id="h-karate-and-postman-similarities"><span id="Karate_and_Postman_8211_Similarities">Karate and Postman &#8211; Similarities</span></h2>



<p>Both Karate and Postman are <a href="https://testsigma.com/qa-automation-tools" target="_blank" rel="noreferrer noopener">automation testing tools</a> explicitly aimed at making the testing of APIs easier, allowing one to check whether the APIs are working, reliable, and performant. They support the testing of both REST and SOAP APIs, thus covering a broad application domain within web services. There are also a couple of features, including mocking servers, offered by both Postman and Karate.</p>



<p>Another similarity between Karate and Postman is that both support data-driven testing. They allow the execution of tests with different data sets to build checks on API working under variant conditions. The tools seamlessly integrate with CI/CD pipelines to have API tests included in the automated deployment workflow for continuous validation and quality assurance.</p>

<h2 id="h-should-i-choose-karate-or-postman-for-api-automated-testing"><span id="Should_I_Choose_Karate_or_Postman_for_API_Automated_Testing">Should I Choose Karate or Postman for API Automated Testing?</span></h2>



<p>The choice between Karate or Postman mainly depends on your exact requirements, what your team is experienced with, and your workflow preferences.&nbsp;</p>



<p>If your team requires a solution that is much richer in capabilities, including API testing, within the same framework without any integration, Karate is most likely the best candidate for you. Its Gherkin syntax makes it easily accessible even to non-developers, whereby stakeholders with less programming knowledge can effectively be involved in the process of creating and maintaining tests. Karate can help with several types of APIs: REST, SOAP, or GraphQL, and, again, integrates with CI/CD pipelines.</p>



<p>Postman, conversely, proves to be a user-friendly development and testing API platform, ideal for teams who consider ease of use and team effort most important. Its intuitive graphical interface easily facilitates the development, testing, and documentation of APIs, meaning it works great for developers and testers. Postman is rich in solid collaboration features, like shared workspaces and version control, making it easy for teams to communicate and coordinate. But for complete automation and integration with CI/CD, some other tooling support or scripting might be needed.&nbsp;</p>



<p>Ultimately, the choice between Karate and Postman would depend on the kind of test you have, the complexity, the technical ability of your team, and the necessity of collaborating on features as part of a workflow.</p>



<h2 id="h-conclusion"><span id="Conclusion">Conclusion</span></h2>



<p>To sum up, Karate and Postman each come with their benefits and different purposes within the software development lifecycle. Karate is particularly potent due to its all-in-one nature and its support for API, UI, and performance testing, with its syntax based on Gherkin. Postman, with its intuitive interface and robust collaboration functionalities, makes API development and testing very easy, and it is popular with teams with shared workspaces.</p>



<p>However, if you are looking for an alternative that brings forward the strengths of both Karate and Postman, then Testsigma is an exciting alternative with a Unified Test Automation platform using a no-code/ low-code interface and a rich set of features. With these taken into careful consideration, you should be able to make a fit tool choice according to the goals and develop a solid and reliable strategy for API testing.</p>
