Testing
Your database going down is not a matter of if — it's when. A disk fills up, a cloud provider has an AZ outage, a runaway query corrupts an index, a network partition isolates the primary. The question is whether your failover mechanism works correctly and whether your application
Testing
Database layers fail in ways that application layers don't. HTTP servers can scale horizontally almost indefinitely — databases hit hard limits around connections, lock contention, and I/O capacity. Stress testing the database independently from the application reveals bottlenecks that composite API tests often miss. Why Database Stress Testing
Testing
Row-Level Security (RLS) is PostgreSQL's mechanism for enforcing data access policies at the database layer. For multi-tenant SaaS applications, RLS is a powerful defense-in-depth tool — even if application-layer authorization has a bug, RLS prevents cross-tenant data leakage at the database level. But
Rust
Database tests are the ones developers skip first. They're slow, they need real infrastructure, they leave state behind that breaks subsequent runs, and they're painful to set up in CI. SQLx and the Rust testing ecosystem have largely solved these problems — #[sqlx::test] auto-migrates and
Database Testing
Prisma has become one of the most popular ORMs in the Node.js ecosystem, and for good reason. Its auto-generated TypeScript client, powerful migration system, and intuitive query API make database work genuinely pleasant. But testing Prisma-based applications requires a clear strategy — one that separates fast unit tests
Database Testing
Sequelize has been a cornerstone of Node.js database development for over a decade. While newer ORMs have taken some of the spotlight, millions of production applications still run on Sequelize, and many teams are actively maintaining large Sequelize codebases that need solid test coverage. Testing Sequelize effectively is more
Database Testing
TypeORM remains one of the most widely deployed ORMs in the Node.js ecosystem, powering everything from enterprise APIs to startup MVPs. Its decorator-based entity system and active record/data mapper duality give you flexibility, but they also create testing challenges that are distinct from newer ORMs like Prisma
Database Testing
Turso has emerged as a compelling database option for teams building edge-first applications. Built on LibSQL — an open-source fork of SQLite — Turso brings SQLite's simplicity and zero-latency reads to the edge, with built-in replication and branching for production workloads. But testing applications that depend
Database Testing
Drizzle ORM has quickly become a favorite among TypeScript developers who want the type safety of a full ORM without sacrificing raw SQL control. But testing Drizzle-powered applications presents unique challenges: the query builder is deeply integrated with the database driver, transactions span multiple operations, and migrations need to
Database Testing
Cloudflare D1 is a serverless SQL database built for the edge — designed to run alongside Cloudflare Workers with zero-latency reads and automatic global replication. But testing D1-backed Workers presents a distinct challenge: your code runs in a Cloudflare Workers runtime environment, not a standard Node.js process, and
Security Testing
SQL injection remains one of the most impactful web vulnerabilities — it appears in the OWASP Top 10 every year and leads directly to data breaches. Testing for it involves probing how your application handles malicious SQL in user-controlled inputs. This guide covers manual detection, sqlmap automation, and parameterized query
Database Testing
SQLite's in-memory mode — :memory: — creates a complete, full-featured SQL database that lives entirely in RAM and disappears when the connection closes. It's been the secret weapon for fast unit tests in every major web framework for over a decade. This guide covers how to
