I personally use Postman for this. It costs 10$ and you can write Tests with it, run Automatic tests. You can export the tests as JSON. Important thing to note is that this is only a Chrome extension.

With a command line tool called Newman from the same company you can run these tests from a console. In the command line you can run the JSON exports.

Ah I see, yeah its more for testing than a specification tool

API specification tool lets you define the APIs - the parameter it takes, the result, the error codes it returns etc. That way a developer knows how to use the API and what to expect. In my opinion, POSTMAN does not qualify to be an API specification tool, but instead an API testing tool.

I am sorry but I am not sure what you mean by that.

When your API gives an error like Not valid!, you can test with Postman for the response body. It will look like this:

tests['testname'] = responseBody === 'Not Valid!'

Everytime this error appears the test will pass.

I've used POSTMAN. For example, can you specify the errors that will be returned by the API in POSTMAN?
