Pact JS End-to-End Example

Using a simple animal dating API, we demonstrate the following Pact features:

• Consumer testing and pact file generation, including advanced features like:
  • Flexible matching
  • Provider states
• Sharing Pacts by publishing to and retrieving from a Pact Broker
• Provider side verification

This comprises a complete E2E example that can be used as a basis for projects.

• The Example Project
  • Provider (Profile API)
  • Consumer (Matching API)
• Running the tests
• Running the API
  • Animal Profile API
    • GET /animals
    • GET /animals/:id
    • GET /animals/available
    • POST /animals
  • Matching service
    • GET /suggestions/:id
• Viewing contracts with the Pact Broker

The Example Project

[Matching API] -> [Profile API]+(DB)

Provider (Profile API)

Provides Animal profile information, including interests, zoo location and other personal details.

Consumer (Matching API)

Given an animal profile, recommends a suitable partner based on similar interests.

Running the tests

1. npm install
2. npm test:consumer - Run consumer tests
3. npm test:publish - Publish contracts to the broker
4. npm test:provider - Run provider tests

Running the API

If you want to experiment with the API to get an understanding:

1. npm run api - Runs the both provider and consumer API

or individually :

1. npm run provider - Runs the provider API (animal service)
2. npm run consumer - Runs the consumer API (matching service)
