Testing uses the Hardhat framework

To run all tests

yarn test

To run individual test files, use

yarn hardhat test <PATH_TO_TEST>

Hardhat does not support native deployments. To aid in deployment, hardhat-deploy is being used. You can see the deployment scripts in the /deploy directory.

Tracer also supports programmatic verification of contracts during deployment. Use the hardhat.config.js file to set your Etherscan API key in order for this to be enabled.

To run deploys to a live network

yarn hardhat deploy --network NETWORK --tags LiveDeploy

This will run the LiveDeployment script which is made to deploy to a real network. If there are any issues with verification, you may run

yarn hardhat deploy --network NETWORK --tags LiveVerify

in order to reverify any deployed contracts.

Some helper scripts have also been created to run deployments and add supporting function calls. For example, DeployAndAddTracer.js runs the FullDeploy.js file and then creates a Tracer market with this deployment.

To run a specific script, run

yarn hardhat run <PATH_TO_SCRIPT>

To generate code coverage metrics via instrumented runs of the testing suite, use:

yarn hardhat coverage

A few important things to keep in mind:

• Code size reports generated by this command (via contract-sizer) cannot be trusted as the instrumentation greatly bloats the generated bytecode
• Running times for tests also cannot be trusted due to the increased overhead of test instrumentation
