📦 Installation

Install as a global .NET tool:

Update to the latest version:

dotnet tool update --global openapi-tests

Uninstall:

dotnet tool uninstall --global openapi-tests

🚀 Quick Start

1. Generate HTTP Test File

Generate an endpoints.http file from your API's OpenAPI specification:

openapi-tests --generate --api-url http://localhost:5000 --http-file TestFiles/endpoints.http

2. Customize Your Tests

Edit the generated TestFiles/endpoints.http file with real IDs and data if necessary:

### Get User by ID (Valid)

GET {{baseUrl}}/api/users/123

### Get User by ID (Not Found - 404)

GET {{baseUrl}}/api/users/999999

# Expected: 404

### Create New User

POST {{baseUrl}}/api/users 

Content-Type: application/json

{

  "name": "John Doe",

  "email": "john@example.com"

}

3. Run Tests

Execute the contract tests:

openapi-tests --api-url http://localhost:5000 --http-file TestFiles/endpoints.http --output Reports

4. View Results

Open the generated HTML report at Reports/contract-test-report.html or in the folder you specified with the --output parameter.

Options

This will:

• --generate or -g: Generate HTTP file from OpenAPI specification

• --api-url <url>: API base URL (default: http://localhost:5225)

• --openapi-path <path>: Path to OpenAPI spec (default: /openapi/v1.json)

• --http-file <path>: Path to HTTP file (default: TestFiles/endpoints.http)

# Expected: 404

### Another Test

GET {{baseUrl}}/another-path

# Expected: 200

# This is a comment
### Create New User

POST {{baseUrl}}/api/users
