Product testing practices havent changed much in thirty years; software testing practices havent changed much in twenty. Automated tests provide both of these things in software. All too often, tests are written after the fact, which leads to best endeavors testing of the software as constructed.

Replay Traffic Testing Replay traffic refers to production traffic that is cloned and forked over to a different path in the service call graph, allowing us to exercise new/updated systems in a manner that simulates actual production conditions. This is particularly important for complex APIs that have many high cardinality inputs.
