Practical stochastic method for CI test optimization with immediate applicability.
Summary
Avoid reducing CI regression test suites at integration/E2E levels, as it obscures subtle bugs. Instead, use stochastic time-series trend analysis to detect regressions across runs and multicontext pattern matching to leverage test redundancies. Improve CI speed via parallelization, continuous reporting, mocking, and hardware-in-the-loop rather than cutting tests.
