WebJun 22, 2024 · It’s unlikely that a random test is going to fail after you’ve run it (hundred)thousands of times and it’s too much effort to write good, dedicated non-random tests just for CI. If a random test does fail in CI: Re-run with the same seed and see if it’s a real bug. If it’s not: fix the test bench or randomness constraints. – WebFirst, let us differentiate between a random walk process and a random set of observations.
