This repository represents a minimal, example package that consumes @statechannels/nitro-protocolas a dependency. It provides a testing environment for interacting with the nitro solidity contracts, using jest.
Clone the repository and cd into the new directory.
Make sure you have Yarn v1.17.3 installed. For easy management of specific Yarn versions, we recommend using Yarn Version Manager (YVM).
To install the dependencies:
yarnExecuting
yarn tutorial lesson1.testwill
- start a local blockchain
- import precompiled contract bytecode from
@statechannels-nitro-protocol - deploy this bytecode
- run a
jesttest test for lesson 1 only
Your task is to make this tests pass, and then move on with yarn tutorial lesson2.test and so on up to lesson 16. Hopefully, you should learn something about the nitro contracts in the process. This exercise would be very useful for anyone interested in building a state channel wallet that runs on nitro protocol.
DApp developers may wish to build against our State Channel Wallet API (coming soon), which abstracts most of the complexity away into a much simpler interface.
Open tutorial/lesson1.test.ts in your text editor. Follow the instructions in a given test case block (starting with it("...) and make the necessary changes. If you have left the test runner open, it should automatically re-run the tests for you (with a brand new, clean blockchain). Individual tests are independent.
You might find that you need to kill the test runner and/or the underlying ganache server, and start again following the steps above if things get into a bad state.
