- Refactor tests into smaller pieces of test cases. 100 lines MUST BE the hard cap limit for every test case, no matter how complex are our contracts. Many lines are just contract initialization setup, therefore, we should move them as test fixtures outside our test cases (the actual logic).
- Use
node-configto easily plug on many Ethereum networks to run tests. Every network will be an environment which maps to specific configuration data (such as gas price, used accounts to test, etc). - Comply to just one standard Ethereum ether basis (finney, szabo, ether,
etc). During tests, we will need to do the proper conversions before and
after the web3 transaction calls. Our goal here is to avoid float-point
arithmetic, after all, they all are prone to tiny fractions of
difference (for instance,
0.0000000000000001), thus, they weak our confidence on tests and on value representation.
