🧪 Automation Testing Simulation

This simulation demonstrates the principles of automation testing in a CI/CD pipeline: a fixed-size test suite is distributed across a configurable number of parallel runner lanes, each pulling the next queued test the moment it becomes free. A per-test flakiness rate drives a real retry-on-failure policy — a test that fails once is retried automatically, and only a test that fails on both attempts is recorded as a final failure — the same mechanism used by real CI systems to keep transient flakes from blocking a build. Live readouts track completion progress, pass rate, retries consumed, measured throughput, and an estimated time remaining derived from the pipeline's own observed speed, showing directly how parallelism and reliability trade off in an automated test infrastructure.
