The useful question about staging and production is what each environment is for, and whether your Playwright configuration reflects that purpose. Staging absorbs risk, so it takes anything that mutates state, fires real emails, or triggers a payment. Production validates that the live system works for real users, which keeps it to read-path flows and a small set of high-signal checks. Most suites blur the two and run one config against both. That’s how a green test ends up hiding a real production break. This article by @currents_dev turns that into a concrete framework: a decision table for placing any test, the configuration that should differ by environment, and the failure modes that show up when teams skip the distinction. How clearly are these two environments separated in your setup? Article link in the comments.

If your team has ever debated "should we mock this or hit the real API," the honest answer is that it depends on five things: - How critical the flow is. - The cost of getting it wrong. - Who controls the API. - Whether a formal contract exists. - What real testing actually costs you in time and quota. This article by @currents_dev breaks that decision down across a five-level spectrum, from no mocking at all to schema-validated and contract-tested mocks. It also covers parts like webhook testing, idempotency keys for real integration runs, and how to clean up sandbox data when ten parallel CI runs share the same Stripe test account. If you're making suite-wide decisions rather than writing one-off tests, this one is for you. Article link in the comments.
