I’ve been learning more about software development and came across the concept of end-to-end testing
, which is different from unit and integration testing. E2E testing is about verifying complete workflows in an application — imagining how a real user interacts with the system from start to finish.
For example, on a website or app, an end-to-end test could cover user registration, sign-in, database updates, and backend integrations, all in one flow.
I’d like to understand more from people’s perspective:
What is end-to-end testing and how does it differ from other types of testing?
Why is it considered essential in modern software projects?
Have you personally used E2E testing tools (like Cypress, Selenium, Playwright)? What was your experience?
What are some common challenges teams face when implementing E2E testing?
I’m trying to grasp how this fits into the software lifecycle and why many developers emphasize its value. Any insights or examples would be very helpful!
