Veriflow is an efficient and straightforward command line interface (CLI) tool designed for executing effective and deterministic end-to-end API testing. This tool leverages a simple JSON configuration file to define and run declarative test flows, allowing for easy testing of APIs without requiring any code changes on the server.

Key Features

• Declarative Testing: Veriflow enables the creation of structured test flows that mimic real user journeys, such as user onboarding, checkout processes, and admin actions.
• Stateful Execution: The tool supports ordered flows, where data can be seamlessly passed between steps (e.g., authentication tokens, user IDs), ensuring accurate test scenarios.
• Zero Code Changes: Tests are executed on the API as a black box, simplifying the process and avoiding unnecessary impacts on the server.
• Comprehensive Assertions: Users can validate API responses through a variety of assertions, including status code checks and JSON/XML content validation.
• Built-in Support for JSON and XML: Automatic detection of response content types allows for straightforward data extraction and verification.

Example Flow Configuration

The following JSON snippet demonstrates how to configure a user authentication flow:

{
    "baseUrl": "http://localhost:8080",
    "flows": {
        "user-auth": {
            "steps": [
                {
                    "name": "register",
                    "request": {
                        "method": "POST",
                        "path": "/api/auth/v3/register",
                        "json": {
                            "email": "user+{{RUN_ID}}@example.com",
                            "password": "secret"
                        }
                    },
                    "assert": {
                        "status": 201,
                        "all": [
                            { "jsonpath": "$.data.username", "exists": true }
                        ]
                    },
                    "exports": { "username": "$.data.username" }
                },
                {
                    "name": "login",
                    "request": {
                        "method": "POST",
                        "path": "/api/auth/v3/login",
                        "json": {
                            "username": "{{bind:username}}",
                            "password": "secret"
                        }
                    },
                    "assert": {
                        "status": 200,
                        "all": [
                            { "jsonpath": "$.data.email", "contains": "{{RUN_ID}}" }
                        ]
                    }
                }
            ]
        }
    }
}
