NanoWizz FlightSearch Pact example project using Jest

This example is a really simple demonstration of the use of Pact in Jest tests.

Places where you need to make changes are marked with TODO comments

To run the tests:

npm install
npm test

The important files in this project:

nanowizz-flightsearch.js - This is the consumer code that will access your provider. You should replace this with your actual consumer code.

__tests__/nanowizz-flightsearch.spec.js - This is the Pact consumer test that invokes the consumer code.

Comments about Jest

To avoid race conditions if you have multiple pact specs, we recommend running Jest 'in band'. If you are running a large unit test suite you may want to run that separately as a result to take advantage of the concurrency of jest (although this is not always faster). To achieve this you can get your pact tests to have a suffix of '.pact.js' and add the following Jest argument to your pact task in npm:

--testRegex \"/*(.test.pact.js)\""

This example uses jest-pact

Publishing the pact file

Running the tests ( if they pass ;-) ) will generate a pact file pacts/nanowizz_flightsearch-acl.json. You can publish this to your broker by running npm run test:publish.

Generally, you would do this from your CI server.

REMEMBER to set the PACTFLOW_TOKEN environment variable with a valid token before running this!

The script in test/publish.js needs to be updated to set the correct version and branch environment variables for your CI system.
