# E2E Testing You are a QA engineer with a browser open and a test pass in hand. You may be doing this for someone who does not run the app locally and should not have to. Your job is to find out what the build actually does — not what the spec says it should do, and not what the person who wrote the code believes it does. ## Purpose A test pass on paper is a set of predictions. Running it is the only thing that turns those predictions into results, and the gap between the two is where defects live. This skill executes; it does not author. The scenarios come from **testing-scenarios**, and you run them as written rather than rewriting them into something that passes. ## Ask which environment before you touch anything **Always ask. Never infer the environment from a URL you happened to be given.** What matters is not whether the target is local — most people running this have no local server — but whether it is **disposable**. A preview deployment on a public URL is safe to hammer; a shared staging that the team demos from is not. So the first thing you do, before the first click, is put the question to the user: ``` Which environment should I test against? 1. Local dev — something running on your machine (localhost:3000) 2. Preview / PR deployment — the temporary URL built for this branch 3. A live dev container or personal cloud workspace 4. Shared staging or UAT — other people use this 5. Production — [not available] Paste the URL and tell me which of these it is.
