MetalBear·41wStop Deploying Just To Test!
Traditional staging environments create bottlenecks when developers deploy every small change for testing. Remocal testing (remote + local) offers an alternative by connecting local applications directly to staging environments without deployment. Tools like mirrord enable this by intercepting network traffic, mirroring environment variables, and proxying requests between local processes and Kubernetes clusters. This approach maintains production-like testing conditions while eliminating build-deploy cycles, reducing feedback loops from hours to minutes, and keeping developers focused on code rather than pipeline management.
Open Source·37wMeet Droidrun- the open source phone agent
Droidrun is an open-source framework for automating Android app UI workflows beyond traditional testing. It enables programmatic interaction with mobile apps through tapping, swiping, and navigation, designed for developers and AI workflows rather than just QA. The framework runs locally with plans for emulator and cloud support, addressing limitations in existing tools around scalability and integration with modern agent frameworks.
DevBlogs·38wIntegration testing for Go applications using Testcontainers and containerized databases
Testcontainers for Go enables integration testing with real database dependencies by spinning up lightweight Docker containers during test execution. The approach eliminates the need for mocking or maintaining separate test environments while providing isolation and repeatability. Using Azure Cosmos DB emulator as an example, the tutorial demonstrates container setup, test execution, and automatic cleanup through the testcontainers-go package. The solution handles TLS configuration, client authentication, and lifecycle management automatically, making it applicable to other containerized services like PostgreSQL and Kafka.
Anton Zhiyanov·40wConcise test assertions with Be
Be is a minimal Go testing library that provides three simple assertion functions: Equal, Err, and True. It offers flexible error checking that can validate error existence, messages, types, and values in a single function call. The package prioritizes simplicity with only 100 lines of code, uses natural parameter ordering (got, want), and doesn't fail tests immediately on assertion failures to show all errors at once.
C# Corner·37wMastering Dependency Injection in .NET Core: A Complete Beginner-to-Advanced Guide
Dependency Injection (DI) is a design pattern that promotes loose coupling, testability, and maintainability in .NET Core applications. The guide covers service registration in Program.cs, constructor injection, three service lifetimes (Transient, Scoped, Singleton), testing with mocked services, and advanced scenarios including factory-based registration and third-party containers like Autofac. Best practices include preferring interfaces over concrete classes, avoiding service locator patterns, and organizing registrations by feature modules.
Awesome·40wNode quietly became surprisingly good...
Node.js has undergone significant modernization driven by competition from Deno and Bun runtimes. Key improvements include ES modules as the default with node: prefix for built-ins, top-level await support, native fetch API, worker threads for CPU-intensive tasks, built-in test runner, and enhanced streams with pipeline API. These changes align Node.js closer to web standards while reducing dependency bloat and improving developer experience.

RUBYLAND·41wYou should delete tests
Challenges the common belief that tests should never be deleted, arguing that tests exist primarily to build confidence in code changes. When tests become flaky, overly brittle, too slow to run regularly, or test outdated requirements, they actually decrease confidence and should be removed. The key principle is that any test that harms rather than helps developer confidence in their changes should be deleted rather than maintained.
