Test coverage

Quick test coverage:

forge coverage

Detailed test logs:

forge test --vvv

Detailed branch coverage:

1. Run

forge coverage --report lcov && genhtml lcov.info -o report --branch-coverage

2. Check coverage results in

report/index.html

3. Delete the following before pushing to GitHub to keep commits lightweight:

lcov.info
reports

Fork a network and get coverage results:

forge coverage --fork-url $mainnetHTTPS_InfuraAPIKey --report lcov && genhtml lcov.info -o report --branch-coverage
