Vitest
Vitest allows you to write tests for your types, using expectTypeOf or assertType syntaxes.

Introducing SafeTest: A Novel Approach to Front End Testing
In this post, we’re excited to introduce SafeTest, a revolutionary library that offers a fresh perspective on End-To-End (E2E) tests for web-based User Interface (UI) applications. The Challenges of Traditional UI TestingTraditionally, UI tests have been conducted through either unit testing or integration testing (also referred to as End-To-End (E2E) testing). However, each of these methods prese
The Golden Rule of Assertions
What if I told you there was a single rule that can reliably tell apart a good test from a bad one? This is not a trick, not a sales pitch. It’s a rule I’ve been using for years to help me refine my tests, make them less flaky and more valuable countless times. In fact, it’s such an indispensable rule in practice that I hereby coin it The Golden Rule of Assertions: A test must fail if, and only if
