RESTful API Testbed with Swagger - api

I'm trying to develop an automated testing suite for a REST API. I've been told that Swagger would be the right tool to use to do this.
The API is being developed using the Spring Framework.
I can't figure out how I would use Swagger to do this.
From my understanding Swagger is used to create nice API documentation.
I've looked at this Dreamfactory blog post and it looks like they've got some kind of in browser testing functionality, but I don't think its really a test suite.
I've also taken a look at ServiceStack( and cucumber) but since its another framework I don't think it would work.
This google group discussion didn't see to point anywhere in particular either.
So, does anyone know how to develop a RESTful API testbed using Swagger?
Thanks!

As the other answers have mentioned, Swagger provides a way to define and document your API endpoints, methods, responses, errors, and more. It does not do any sort of automated testing out of the box.
There are a few tools that can read a Swagger definition to created automated tests, though:
Assertible is a tool where you can import your Swagger spec to automatically create tests and assertions for every endpoint and method. You can then set up monitoring, post deployment testing, and alerts. (Read the blog Testing an API using Swagger). It has a free plan with options to upgrade for more tests.
swagger-test is an NPM package, if you're looking for something to integrate with your code. I haven't personally used it, but it does look active and useful.
Dredd is another really cool open-source tool that will automate testing your Swagger spec against a live backend. This is also a CLI too, and it works with API Blueprint in addition to Swagger.
There's others as well, because Swagger provides a good common language for API developers there's some great tools that are written on top of it.
Another answer mentioned to check out the Commercial Tools page on swagger.io, which has some more hosted services (free and paid).
Full disclosure - I'm one of the co-founders of Assertible and would love to hear your feedback if you get a chance to use it.

Swagger will let you nicely document your API, and will help you do manual, live tests with swagger-ui in that you can easily fill in arguments and see the responses through a web ui. Try the Swagger demo as an example of what I am referring to. http://petstore.swagger.io/
I have not tried this, but this might be of interest for more automated testing against Swagger definitions.

You can find a lot of software using Swagger specification for (automated) testing of your REST API on http://swagger.io/commercial-tools/. But they are not free.

Postman is great tool to test with Swagger apis. It can also store requests and responses. More details as follows
https://www.getpostman.com/docs/importing_swagger.
You might also want to look at the community tools according to languages at this page. http://swagger.io/open-source-integrations/

I have written an article on how you can generate all the test logic by using the Swagger or OpenAPI specifications. And then feed test data through excel sheets. That way your test data and test logic remain separated and in future if your Swagger spec changes then you will be able to even quickly re-sync the test logic.

Does exist a universal tool to describe different APIs (REST, WebSocket, gRPC, custom framework)?

My project uses different protocols to communicate with other services:
REST API
WebSocket (STOMP)
gRPC
own framework build over gRPC.
I need a tool, or a bunch of tools, which allow me to generate documentation for the APIs. In the best scenario, it's a maven plugin that generates a report with all APIs.
We use Swagger to describe the REST API. It has poor export options and needs a lot of annotations in the code, but describes the API well and offer the test machine.
Alternatively, Spring RestDocs (AsciiDoctor) could be used for the REST API describing. It offers a better format for reporting, but we prefer Swagger.
That's all I found for the REST API. But I didn't find anything for describing WebSocket API, gRPC and the custom framework.
I will be very grateful for any help and ideas to solve the problem.

Is there a testing framework that will support GraphQL, web app testing, and mobile?

I have started to use Karate to test our mobile app which is using GraphQL and it is working good so far, though a bit of a learning curve for me as I am not a programmer by trade, but I need to look further into the future and be sure to find a framework that will also support our need to automate tests for our custom web applications as well. I would think Selenium would be the way to go so I am looking for a testing framework where I can test not only the GraphQL queries which our micro services/APIs are written, but also our web applications and our mobile app. We are a MS shop but if need be, as with Karate, we can venture into a different stack. Thanks!
Disclaimer: dev of Karate here.
I don't know about mobile, but teams have been successful mixing Karate and Selenium / WebDriver into a single integrated script, which is possible because of Karate's Java inter-op.
This is a Stack Overflow answer recommending the above approach and this answer is an update from the same team reporting success.
One more reason you may want to consider Karate is that it may be the only framework that allows you to re-use functional test scripts as performance tests, via Gatling integration (still in development).
Karate in my opinion is a "safe" choice as a testing framework, because it is technically Gherkin and "language neutral". This may be a surprise for those new to Karate, but it actually leans towards using JavaScript for scripting instead of Java.
Of course, it is worth mentioning that I have yet to find a framework that makes testing GraphQL as easy as how Karate does.
Selenium and Rest assured integration framework is the answer to your question. I created a test automation framework to test an ionic application which is using GraphQL api along with Rest webservices. I have used Testng and cucumber in my framework to perform web app side validations and used Rest assured along with GSON to validate the GraphQL and rest services. You can easily integrate appium in your framework along with selenium and rest assured to cater the need of mobile testing.

Is there any solution for generating the restfual api code both for client and server

The functions for operating the restful api is quite same. Is there any project that can generate the source code for different platform such android,ios and backend stuff.
I suggest you to use API description languages such Swagger ou RAML.
After having described your RESTful application with a language like this, you will be able to generate things like server skelekons and client sdks with different technologies and languages. You can even generate documentations.
With Swagger, swagger-codegen will do that. swagger-ui may also interest you for the documentation part.
To finish, I would like to mention the Restlet studio that allows to define graphically and quickly the structure of RESTful applications and generate then the corresponding Swagger and RAML contents. The APISpark plaform provides a mecanism to introspect Restlet applications and generate the corresponding contents with these languages. It also allow you to generate a set of server skelekons and client sdks.
Hope it helps you.
I will suggest you to use Spring RESTful webservices starter kit. Which will manage your back-end with centralized database. Also Spring has its own android libs to communicate with REST Apis.

Generating REST API Documentation from Restlet annotations

The RESTful Web service APIs are implemented using Restlet. I need to generate the API documentation for these. Rather than starting with a separate document, I am evaluating if this can be generated from the source code annotations itself.
I looked at Swagger and enunciate. Swagger seems to be based on the JAX-RS specification. Enunciate looked a little more promising as there is an FAQ that mentions how to generate for non JAX-RS implementations but there is no help.
Are there any tools (or if the community has used any) for generating API documentation from Restlet annotations?
Has anyone integrated Restlet with enunciate for generating documentation?
Restlet now supports the ability to generate either corresponding Swagger and RAML contents based your application at runtime.
Following docs could help you:
For Swagger (extension org.restlet.ext.swagger): see http://restlet.com/technical-resources/restlet-framework/guide/2.3/extensions/swagger
for RAML (extension org.restlet.ext.raml): see http://restlet.com/technical-resources/restlet-framework/guide/2.3/extensions/raml
You can then leverage tools from the tool community to generate your API documentation. You could consider Swagger UI that is a great tool to display online what an API provides and interact with it.
Hope it helps you,

What online REST API workbenches are available?

When creating a site/script to be on the client end of a RESTful API, what tools are available to create a "workbench" to explore the API, examining headers and responses while working through the design? Preferably one(s) that allow you to enter a custom endpoint, and create sample requests to see the responses. I recall seeing one nice workbench before, but its name has escaped me.
Re-found the one I remembered: The Apigee Console is a great interface for playing around with an existing API or building your own.
Mashery's I/O Docs is an open source workbench that you can deploy yourself on a Node.js server with Redis for storage.
If you have the wadl file of the ReST Services, you can load it in SOAP UI and use it.
