Behave Restful is a Behavior Driven Development (BDD) framework based on behave, that implements a language suitable to test and validate REST APIs and Services. It leverages the power of the gherkin language to write business readable tests that validate the behavior of REST APIs.
Although, Behave Restful is implemented in python and uses behave as underlying framework, it can test services implemented in any language as easy as:
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"As you can see in the example, we send a POST request to the specified url with a JSON payload, and we can validate the result very easy. First, we verify that the status of the response is CREATED (it succeeds). Then we validate the response JSON body using the expected JSON Schema. Finally, we validate specific values in the response using JSONPath
Installation
Use pip to install behave-restful in your project
pip install behave-restfulSetup
To add support for behave-restful steps in your .feature files, you need to include behave-restful’s environment and step definitions.
You can do this simply by adding two boilerplate files to your project:
In the root of your features directory, add this environment.py file:
# {your_project}/features/en/__init__.py
import os
import behave_restful.app as br_app
def before_all(context):
this_directory = os.path.abspath(os.path.dirname(__file__))
br_app.BehaveRestfulApp().initialize_context(context, this_directory)
context.hooks.invoke(br_app.BEFORE_ALL, context)
def after_all(context):
context.hooks.invoke(br_app.AFTER_ALL, context)
def before_feature(context, feature):
context.hooks.invoke(br_app.BEFORE_FEATURE, context, feature)
def after_feature(context, feature):
context.hooks.invoke(br_app.AFTER_FEATURE, context, feature)
def before_scenario(context, scenario):
context.hooks.invoke(br_app.BEFORE_SCENARIO, context, scenario)
def after_scenario(context, scenario):
context.hooks.invoke(br_app.AFTER_SCENARIO, context, scenario)
def before_step(context, step):
context.hooks.invoke(br_app.BEFORE_STEP, context, step)
def after_step(context, step):
context.hooks.invoke(br_app.AFTER_STEP, context, step)
def before_tag(context, tag):
context.hooks.invoke(br_app.BEFORE_TAG, context, tag)
def after_tag(context, tag):
context.hooks.invoke(br_app.AFTER_TAG, context, tag)And under features/steps add this __init__.py file:
# {your_project}/features/steps/__init__.py
from behave_restful.lang import *1 maintainer
