  "account": "Verification-email tests have four key components: a unique address for each test run, the browser flow that triggers the send, a method to read the message arriving, code extraction, and the assertion. Steps 1 and 3 are commonly misunderstood, as they often involve sharing a single mailbox among all tests. To avoid this, each test should have its own dedicated inbox that is created and discarded after the test is complete.\n\nMoeMail provides an open-source disposable-inbox API with a REST interface, making it suitable for CI suites. To use the service, simply replace the base URL and authentication header if you opt for a different provider. The inbox function creates an inbox with a specified expiration time in milliseconds and returns an object containing the inbox ID and email address.\n\nPlaywright fixtures can be used to simplify the integration of this functionality. By extending Playwright's test function with the inbox object, every test automatically receives a fresh inbox address without having to manually manage it. This allows the focus to remain on the test behavior rather than the underlying email infrastructure.",
  "summary": "Most \"email testing\" advice ends at stubbing the send call. You assert that your app tried to send a message, and the test goes green. That leaves the interesting half untested: whether the message actually left your infrastructure, whether the template rendered, and whether the six-digit code inside it matches the one your backend is willing to accept. This walks through the other approach —…",
