Investing in Testing with Reason
summary
Reason Native’s testing framework Rely concentrates on concrete payoffs: encode business rules in the type system so adding mismatched currencies is a compile error, use phantom types to enforce lifecycle order, and apply builder patterns to avoid mass test breakage. The stack runs 5,000 tests in about a second (first run ~15s subsequent ~3–7s) and claims nearly 100% code coverage, shifting effort from brittle unit maintenance to relevant integration checks.
