Can I write API contract tests (consumer driven) using RestAssured framework? - rest-assured

I wanted to implement some contract tests and was looking at different frameworks like Pacto, Postman etc. I am familiar with RestAssured so just wanted to ask if it is possible to write api contract tests using Restassured and are there any good examples of it ?

Here is an article about that : https://hmh.engineering/how-to-write-and-validate-pact-contracts-using-junit5-and-restassured-72b578e7dd65

Getting the Swagger/OAS definition of the REST APIs

Quick and simple: Is it possible to get the complete OAS/YAML/JSON definition of these APIs? For example the ESIGN API.
I want import these definitions and generate a connector to do a low/zero coding implementation.
Thanks in advance.

Alejandro, you're in luck.
DocuSign uses the OpenAPI (OAI) Specification - formerly known as "Swagger" - to describe its REST APIs. The goal of the OAI specification is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service. For more info see the official OAI spec.

RestAssured vs Mockmvc for unit and integration testing

I am asked to choose one and the best from these two for unit and integration tests-
1. RestAssured
2. Mockmvc
The application is in Spring and Spring Boot. I have read many blogs and no clear distinction is given or I couldn't find one. For rest assured, its neat and clean code and BDD style that makes it more readable. But doesn't sound a convincing point. Some of the tests are written using Mockmvc and I am trying to write the same in RestAssured to compare the same.
I know this may sound a theoretical question but I am unable to get points in favor of one and suggest which one is better and why. Looks like a choice of flavor to me. Any views and suggestions?
You would choose MockMvc for web layer testing. These tests will allow you to validate your controller classes properly handle respective HTTP requests. Since these are practically fine grained controller unit tests, you can additionally include them as part of your apps’ code coverage percentage with tools like JaCoCo. On a side note, these tests will likely run faster than integration tests since they won’t require the web server to run on.
RestAssured is used for integration testing in your Spring Boot app. When it comes to RESTful based API integration testing and validation, RestAssured offers convenient methods to create and execute your HTTP calls with custom headers, auth, content types, query parameters, payload content, cookies, etc.
To aid your comparison check out this article - Testing Spring Boot RESTful APIs using MockMvc/Mockito, Test RestTemplate and RestAssured - it has a good explanation and robust examples on the usage for RestAssured and MockMvc.

How to use specs2 to test spray-swagger REST API endpoints?

spray-swagger appears to be a good way to auto-generate documentation as well as client stubs for a REST API. Is there a way to automatically test these APIs using specs2?

how to read data from api without any gem rails 3

I want to read data from an API ean without using any gem. What I want is when the user searches for a particular hotel then my query should return me a data from ean.
How can I go about this thing? and how/where do I add the api key and secret ?
You can perform HTTP requests in Ruby using the Net::HTTP standard library.
Most people prefer to use third party Gems because they offer additional features or cleaner API, compared to Net::HTTP.
However, most of them is based on Net::HTTP itself.
Its a soap API you can use savon to build your own class to access that api. YOu will find a screencast for savon here: http://railscasts.com/episodes/290-soap-with-savon I had a look at the documentation its pretty well documented.

Skip API calls on tests

I make API calls when create a user but I don't want do this calls on test environment.
What do you do with on this situations? I have external APIs like Mailchimp and internal APIs to communicate with others apps, how do you to test or not this APIs?
Mocking API is the purpose of fakeweb presented in this railscast.
I think you need to mock your API calls then using some mocking libraries for Ruby.
