How to Test a Business Network Definition

After you have deployed a business network definition it is often useful to run a "smoke test" to ensure that the deployment was successful. The composer CLI exposes several commands for running such smoke tests.

In addition you can write full-blown system tests using Docker Compose and Chai, that start a Fabric, deploy your business network definition and then programmatically create assets, submit transactions and inspect the state of asset registries.

Creating Assets

Use the composer-client module and the BusinessNetworkConnection API to add assets to an asset registry.

Viewing Registries

composer network list

Submitting Transactions

composer transaction submit

Writing Assertions

Use popular Javascript assertion libraries such as Sinon and Chai.

Generating Tests

You may choose to add skeletal tests to your application using the composer generator tests command.
