When a test suite exhibits intermittent failures, developers often turn to RSpec’s --bisect flag to find the minimal set of examples that reproduces the problem under a fixed random seed. The goal is to decide whether the observed flakiness stems from order‑dependent state leakage or from other sources such as timing, concurrency, or external service calls,
rspecCan git bisect run distinguish a true regression from a flaky test failure?
When using git bisect run to automate regression hunting, the goal is to let Git interpret a test script’s exit code as a reliable indicator of whether a commit is good or bad. However, the script may fail for reasons unrelated to the code change—such as a flaky test, a temporary dependency timeout, or an environmental hiccup—yet Git treats any non‑zero exit
