The emergence of SPAs, and therefore logic-heavy client-side code, drastically changed the game for front-end developers. As a result, for the last couple of years, we have had to catch up with sophisticated techniques to build high-quality applications—one of the essential being testing.

More and more people started to add tests to their Vue. js-powered applications. With varying degrees of success. The field is still relatively new, and we all need more experience in how to test client-side applications most effectively.

With my talk, I want to walk through 1) how to come up with a solid testing strategy (tools and practices) and 2) work on a real-world example of how we combine E2E testing with component testing.

I want to highlight some general principles from testing theory and then go into the practical application—live coding in a TDD manner.
