If you need CLI support for API testing, the best choices are usually:
Good options
-
cURL
- Built into many systems or easy to install
- Great for quick one-off requests
- Best for simple manual testing
-
HTTPie
- More human-friendly than cURL
- Cleaner output and easier syntax
- Good if you want CLI testing but prefer readability
-
Postman with Newman
- Postman is GUI-based, but Newman lets you run Postman collections from the command line
- Best if you already use Postman and want CI/CD integration
-
REST Assured / Karate
- Better for automated API test suites
- Useful if you want tests version-controlled and run in pipelines
- Karate is especially nice for API-focused testing with readable syntax
Quick recommendation
- For manual CLI testing: use HTTPie or cURL
- For automated test suites: use Karate or REST Assured
- If you use Postman already: use Newman
If you want, I can also recommend the best tool based on whether you’re doing manual testing, automation, or CI/CD.
