Streamlining REST API Testing with Behave Restful

In today’s rapidly evolving digital landscape, the need for robust and reliable REST APIs has never been greater. As businesses strive to deliver seamless and efficient user experiences, thorough and accurate testing of these APIs becomes imperative.

Introducing Behave Restful, a powerful Behavior Driven Development (BDD) framework built on top of the widely-used Behave framework. Behave Restful provides a language suitable for testing and validating REST APIs and Services, allowing you to write business-readable tests that validate the behavior of your APIs.

Features and Functionalities

Behave Restful offers a range of features and functionalities designed to simplify the testing and validation process for REST APIs. Some key features include:

• Easy integration: Behave Restful can test services implemented in any programming language, allowing you to seamlessly integrate it into your existing tech stack.
• Business-readable tests: Behave Restful leverages the power of the Gherkin language to write tests that are easily understandable by both technical and non-technical stakeholders.
• JSON Schema validation: Validate the response body using JSON Schema, ensuring that your API responses adhere to the expected structure.
• JSONPath support: Easily validate specific values in the response using JSONPath expressions.

Who Can Benefit from Behave Restful?

Behave Restful is incredibly versatile and can be beneficial for multiple stakeholders involved in the development and testing of REST APIs. Some key stakeholders who can benefit from Behave Restful include:

1. Developers: Behave Restful provides developers with a powerful tool for testing and validating their REST APIs. With Behave Restful, developers can write tests in a language that is easy to understand and can catch issues early in the development cycle.

2. QA/Testers: Behave Restful makes it easy for QA testers to write comprehensive tests for REST APIs. The language used in Behave Restful is business-readable, which means that QA testers can collaborate with business stakeholders and ensure that the APIs meet the expected behavior.

Real-World Use Cases

To illustrate the applicability of Behave Restful, let’s consider a real-world use case. Suppose we want to test an API that adds a new book to a collection:

“`gherkin
Feature: API to add a new book to our collection
As a user, I want to add a new book to my “to-read” collection.

Scenario: Add a new book to collection.
    Given a request url http://my.reads/api/books
        And a request json payload
            """
            {
                "category": "reference",
                "author": "Nigel Rees",
                "title": "Sayings of the Century",
                "price": 8.95,
                "status": "to-read"
            }
            """
    When the request sends POST
    Then the response status is CREATED
        And the response json matches
            """
            {
                "title": "BookObject",
                "type": "object"
                "properties": {
                    "id": {"type": "number"},
                    "category": {"type": "string"},
                    "author": {"type": "string"},
                    "title": {"type": "string"},
                    "price": {"type": "number"},
                    "status": {"type": "string", "enum": ["to-read", "reading", "read"]}
                },
                "required": ["id", "category", "title"]
            }
            """
        And the response json at $.id is equal to 100
        And the response json at $.category is equal to "reference"
        And the response json at $.title is equal to "Sayings of the Century"

“`

In this example, we send a POST request to the specified URL with a JSON payload, and then validate the result. We first verify that the status of the response is CREATED, indicating a successful operation. Next, we validate the response JSON body using the expected JSON Schema. Finally, we validate specific values in the response using JSONPath expressions.
