Example JS project for the Pact workshop

Step 1: Run the consumer test

Demonstrates:

• that we can put assumptions in our unit tests that aren't valid
• Pact tests are nothing scary, and look much like the use of nock

Running step 1:

npm run test:consumer
npm run test:pact:consumer
npm run test:pact:publish

Step 2: Write the provider test

Demonstrates:

• the assumptions in step 1 by the consumer team are wrong (failed test)
• teams need to communicate with each other
• use of flexible matching to make tests less brittle

Running step 2

npm run test:pact:consumer
npm run test:pact:publish
npm run test:pact:provider

Two problems

1. qty -> quantity difference
2. value -> itemValue

Step 3: fix provider test

Demonstrates:

• fixes qty and itemValue properties in provider test
• contract testing validates assumptions from both collaborators

Running step 3

npm run test:pact:consumer
npm run test:pact:publish
npm run test:pact:provider

Step 4: Broker / Can-i-deploy

Demonstrates:

• sharing and collaborating on contracts via the Pact Broker
• how you might integrate Pact into your CI and CD pipelines

Running step 4

npm run test:pact:consumer
npm run test:pact:publish
npm run test:pact:provider
npm run can-i-deploy:consumer
npm run can-i-deploy:provider
