Test Automation
Schema evolution is one of the most underappreciated risks in event-driven architectures. A producer team renames a field, removes a required field, or changes a type — and downstream consumers start failing silently or crashing at runtime. Confluent Schema Registry solves the governance problem by enforcing compatibility rules, but only
Testing
Orthogonal array testing is one of those techniques that gets mentioned in ISTQB study materials and promptly forgotten because the explanation is usually too abstract to be actionable. It shouldn't be. Orthogonal arrays are a concrete, table-driven approach to combinatorial test design with a clean mathematical basis

AUTOSAR is the software architecture that underpins most modern ECUs. If you're testing automotive software without understanding AUTOSAR's layering, you're either testing the wrong things or missing entire failure modes. This post covers practical testing strategies for both AUTOSAR Classic (CP) — the real-time
Database Testing
ORMs hide SQL behind object abstractions, which makes application code cleaner but creates a testing trap: it's tempting to mock the ORM and test nothing real. Mock-based ORM tests can show 100% coverage while completely missing query logic bugs, N+1 problems, and constraint violations that only
AI Testing
Traditional test automation has a cost problem: it requires skilled automation engineers, significant time investment, and ongoing maintenance. Autonomiq (acquired by SAP in 2021, now part of SAP's testing portfolio) tackled this with scriptless, AI-driven test automation — letting teams create and run tests using natural language without
Alerting
Test failures don't keep business hours. When your CI pipeline breaks at 2 AM or a production regression surfaces on a Friday afternoon, you need the right person paged immediately — not buried in a Slack thread nobody checks until Monday. OpsGenie is Atlassian's on-call management
Testing
Decision tables are a test design artifact. Their value is only fully realized when the rules they define become automated tests that run on every build. A decision table sitting in a spreadsheet catches nothing — it's a plan, not a verification. This post covers how to turn a
Testing
OpenXR standardizes XR APIs across runtimes, but runtimes still differ in behavior, extension support, and performance characteristics. Test against each runtime you ship on. Use the Khronos OpenXR Conformance Test Suite for spec compliance, test input paths explicitly against each controller profile, and run your CI against the OpenXR loader

OpenTofu is the open-source, community-driven fork of Terraform, created after HashiCorp changed Terraform's license from MPL to BSL 1.1 in August 2023. If you've been using Terraform — and especially if you've built tests with Terratest or the native .tftest.hcl framework
Game Testing
Game UIs are notoriously undertested. Most teams apply automated testing to gameplay logic and leave menus, HUDs, settings screens, and inventory UIs to manual QA. This is understandable — game UI testing is genuinely harder than web UI testing — but it leaves a class of bugs that consistently escape to players:
Enterprise Testing
OpenText (formerly Micro Focus, formerly HP) operates the largest portfolio of legacy enterprise testing tools. UFT One (Unified Functional Testing), ALM (Application Lifecycle Management), LoadRunner, and Fortify together cover the full testing lifecycle at enterprise scale. For organizations already invested in this ecosystem, understanding how the tools work together is

Lighthouse catches a useful set of SEO and accessibility issues, but it misses a lot. This guide covers the tools and techniques that go deeper: axe-core for WCAG compliance, Pa11y for CI integration, custom Playwright assertions for your specific patterns, and how to combine them into a coherent automated
