Usar interfaces facilita el unit testing, desacopla tu código. Si sumas Moq en dotnet, simulas la que quieras y todo va bien. #unittesting #moq #dotnet

Many Flutter widget tests fail after harmless UI changes. The feature still works. The test breaks. That usually means the finder targets the wrong thing. A text-based finder ties the test to copy. Rename “Continue” to “Next” and the test fails, even though the action still triggers the same navigation. A deep find.byType ties the test to structure. Move a widget one level up and the test fails, even though the screen behaves the same. The test couples to implementation instead of behavior. A better approach anchors the finder to intent. Pick a stable handle for the interaction, then scope it to the right area when the screen contains multiple similar elements. A well-placed key on a primary action removes dependence on wording and layout depth. A scoped descendant keeps precision without hardcoding the tree. This changes failure modes. The test now fails when the behavior changes, not when the UI gets reorganized. Minimal example in the visual. Tests should break on regressions, not on refactors. #flutter #dart #softwareengineering #mobiledevelopment #softwaretesting #unittesting #widgettesting #cleanarchitecture #testing #devtips #programming #developer

Вот собрал тут что важно по хардскилам, вместо ваших алгоритмов, литкода, высоконагруженных кабанчиков и карго-культа микрооптимизации: - Data structures (just how to use) - Type systems: nominal, structural, variance... - Modularity system (in your language) - Polymorphism (Ad-hoc, Subtype, Parametric, etc...) - Structural composition, aggregation, delegation - Functional composition, pure functions - Abstraction layers separation - Dispatch and Dynamic dispatch - Referential transparency - Law of Demeter - Referential transparency - Abstract data types (ADT) - Hidden and explicit state - Lazy evaluation - Declarative vs imperative style - Recursion versus loops - Generics (generic programming) - Separation of concerns - Isolation, interfaces, architectural boundaries - Dependency injection and Inversion of control - Coupling and cohesion - Mutable vs immutable data - Idempotent operations - Naming conventions - Error handling - Refactoring, code review process - Tests (unittesting, coverage, end-to-end...) - Multiparadigm programming - Metaprogramming (codegeneration and dynamic) - Platform-agnostic, framework-agnostic approach - Domain-Specific Language (DSL), Interpreter, AST - Contract programming - Concurrency and Asynchronous programming - Separation of system and applied code - Language and semantics - AI-assisted engineering Но все это тоже должно занимать в голове не более 30% от развития инженера, as of 2026. Про 70% напишу еще чуть позже

Most AI agents don’t fail because they’re dumb. They fail because there’s no truth layer. That’s what we built with Themis — now live on the Tessl Skill Registry 👇 tessl.io/registry/vitron-ai/… ⚖️ Turn outputs into verdicts 🧠 Replace prompts with testable logic 🔁 Make agents repeatable deterministic This isn’t just “better prompting.” It’s a shift from generation → validation. Your agents shouldn’t just write code… they should prove it works. If you’re building with AI, this is the missing layer. Install. Evaluate. Ship truth. #AI #Agents #Testing #E2E #unittesting #DevTools #OpenSource #Tessl #agenttesting #aiagentskills
