Core

Snickerdoodle Core Test Harness

Package Contents

  • src: source code for the testing the Core package and running a minimal aggregation service in the form of an Express server

Summary

This package provides a CLI interface for running and testing the Core package. After running it with yarn start, it will start a persistent copy of SDC and give you a menu of options for interacting with the core. The core operates asyncronously, so you may recieve notification of events recieved.

This harness amounts to a bare-bones form factor, and thus has to follow the processes of any form factor when interacting with the core. Thus, it is an excellent proving ground for patterns in SDC.

Getting Started

Test Harness Demo

As currently configured, this package is meant to run locally, and not INSIDE a docker environment. That will be the next upgrade. It is an interactive CLI app, and can be exited via the in-app menu or via ctrl-c. Use yarn start to start the app, which will compile the code and run it with ts-node.

Step 1

At the top level of the protocol repository, start a local Hardhat node and IPFS node:

cd /protocol
yarn install
yarn start

Step 2

After the Hardhat and IPFS containers have started, open a new terminal, move to the test-harness directory and start the CLI:

cd /protocol/packages/test-harness
yarn start

Step 3

After the CLI start, first select "Core" and unlock one of the pre-seeded test wallets.

Step 4

Next, select "Insight Platform Simulator" and create a campaign which will deploy a Consent Contract from the Consent Contract Factory in the Hardhat node.

Step 5

Select Core again and opt into the consent contract you just deployed when creating a campaign from the platform simulator.

Step 6

Now that you have opted into a campaign, Core will respond to requestForData events. Select "Insight Platform Simulator", then select "Query", choose the campaign ID you just created, and finally select which query you wish to broadcast.
