Testing the entire user flow from the interface through backend, database, and integrations to the expected outcome. Detects issues that individual unit or module tests would miss.
Why it matters
Validates the system as a human would use it: from clicking in the browser to data being saved in the database. Catches failures at module interfaces that unit tests cannot detect.
What's missing without it
Without end-to-end tests, each module may work individually, but the system as a whole may fail — the user discovers this first.
When it is used
For critical user paths: login, publishing, purchase, shipping — run before deployments.
How we use it
An E2E test logs in an editor, creates an article, triggers TTS, and verifies the audio file appears in the media section.
