Automated Regression Suites

Automated regression suites are collections of test scripts that are executed every time the code is modified to ensure that new changes do not break existing functionality or introduce security regressions. In the context of complex financial protocols, these suites must cover not only functional requirements but also security invariants, such as ensuring that the total supply of a token remains constant or that collateral ratios never drop below a safe threshold.

By running these tests automatically, developers can immediately identify if a change in one module has had an unintended side effect on another. This provides the confidence to iterate quickly and continuously improve the protocol without the fear of introducing catastrophic bugs.

A well-maintained regression suite is one of the most important assets for any professional development team, serving as a living record of the protocol's security requirements and expected behavior.
