Unit-Testing on a Local Chain Is Important, Because It Helps

question 65

Multiple Choice

Unit-Testing on a local chain is important, because it helps you:

• A) to run tests quickly and especially for free, compared to continuous deployment on the MainNetwork. This way you save a lot of fees, time and costs.
• B) to run tests in an environment where logging is activated. On the Main-Net you have no access to transaction logs and this is ultimately the information you need to debug your contracts.
• C) to avoid regression bugs with contracts that are updated constantly on the main-net. Once you update a contract on the main-net, the address stays the same, but the code changes and this can have disastrous side-effects.
