What does "end-to-end test" mean in programming?
end-to-end test is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A test that verifies an entire user flow from start to finish, simulating real user interactions in a real browser or environment. E2E tests catch bugs that unit and integration tests miss because they test the full stack together. Common tools: Playwright, Cypress, Selenium.
Example
"The E2E test signs up, adds an item to the cart, checks out, and verifies the confirmation email — the full user journey."
