 In addition to running its own test suite, the CI for this gem also runs [money's](https://github.com/RubyMoney/money/tree/main/spec) and [money-rails's](https://github.com/RubyMoney/money-rails/tree/main/spec) test suites with this gem loaded, to prevent regressions. This has been achieved by cloning their test suites from GitHub and requiring this gem in their spec files. For technical information, check the CI [workflow](.github/workflows/ci.yml).
