As LLMs generate more of our daily repetitive coding, robust tests are essential for keeping regressions out of production. 🙅 At Glovo, we streamlined our backend microservice testing to ensure our suites speed up pipelines, reduce regressions, and ultimately sustain a system that constantly scales. Milestones of a strong test suite: 👉 Resilient Refactors: Tests don’t break if the underlying business logic hasn't changed.  👉 Reliable Contracts: Integration tests that actually catch infrastructure issues (serialization, header, timeout).  👉 True E2E Validation: Verification of critical side effects through real application wiring. The goal for implementing a strong testing strategy is to maximize confidence for the users. In his latest article, Hernán Malatini breaks down the mindset shift and practical guardrails designed to do exactly that. Get the behind-the-scenes look here 👉 https://lnkd.in/dS-97EcP
