When would you use KARATE?
Karate Framework is an open-source
Behavior Driven Development (BDD) testing framework for
API test automation,
performance testing, and
UI testing. It can script calls to HTTP end-points and assert that the JSON or XML responses are as expected.
When would you use POSTMAN?
Postman is an
API client that makes it easy for developers to
create, share, test and document APIs. With this open-source solution, users can create and save simple and complex HTTP/s requests, as well as read their responses.
When can we use both of them?
Always. It is different tools, check details above.
- Postman is a great tool when trying to dissect
RESTful APIs made by others or test ones you have made yourself.
- Karate Framework is an open-source Behavior Driven Development (BDD) testing framework for API test automation, performance testing, and UI testing.
Karate is built on top of
BDD testing framework, and shares some of the same concepts. One of these is the use of a
Gherkin file, which describes the tested feature. However, unlike Cucumber, tests aren't written in Java and are fully described in the Gherkin file.
Both tools can be integrated into CI/CD pipelines.
Continuous integration and continuous delivery (CI/CD) are a core part of the API development workflow. Postman integrates with popular CI tools so you can view details about API builds in the same place where you define and test your API.
KARATE test framework pipelines has standard Java / Maven project structure, and seamless integration into CI / CD pipelines - and support for JUnit 5.
Both tools can be used for API test automation, performance testing.
KATATE also has UI testing. It is
Java based tool.
It depends on your project needs.
You can use any of them or use only one of them.
Use cases for Postman:
- you are developer and want to
create, share, test and document APIs.
- you want to create and save simple and complex HTTP/s requests, as well as read their responses.
- you want to do some light load testing.
- you are not common with programming too much.
Use cases for KARATE:
- you are common with Java and Java ecosystem (Maven, TestNG, JUnit).
- you can use this framework even if you are common or not with programming.
- you want to do some API test automation.
- you want to do some performance testing.
- you want to do some UI testing.
- this framework will be good for you if you are common with Selenium WebDriver test automation approach.
