Lately I’ve noticed that more and more service seem to include API testing in their list of services. For instance this week at Chirp, Twitter announced their development console available on dev.twitter.com which gives you the ability to test the API without really having to write any code just yet.
This feature is also well known for people using Hurl which is a website that you can use to make HTTP requests and test your API responses. Also on OSX there’s the HTTP Client Tool which does more or less the same as the ones above.
Another company that announced this feature this week was Apigee:
Use the API Console to review an API’s structure, experiment with the endpoint, and review the request and response messages. We’re launching with support for Twitter APIs and are adding more soon
Apigee is basically an analytics tool for your API. It allows you to track requests, users, errors, etc. So for them, implementing the API tester is something that makes sense as they provide statistics for you API, if you notice an error, you should be able to just test the API call and see if you can reproduce from within Apigee.
