Testing
Hiring QA engineers is harder than hiring software engineers because the role is more ambiguous, the candidate pool is smaller, and most interview processes are borrowed from SWE hiring without adjustment. This guide gives engineering managers a complete framework: role definition, job description, interview structure, five essential questions with rubrics,
Security Testing
Trivy is an open-source vulnerability scanner that covers container images (OS packages and application dependencies), Kubernetes manifests, Terraform, Dockerfiles, and secrets. It's fast, requires no setup beyond installation, and produces structured JSON or table output. Use Trivy in CI to block builds with critical vulnerabilities before they reach
Testing
DeepSource combines static analysis with automated code fixes — it doesn't just report issues, it opens PRs to fix them. This guide covers DeepSource setup, autofix configuration, coverage enforcement, and integrating quality gates into your CI pipeline. What Makes DeepSource Different Most code quality tools report problems and stop.
Testing
BigCommerce testing spans the Management API (products, orders, customers), the Storefront API (cart, checkout), and the Stencil theme layer. This guide covers each with Python and JavaScript examples, including complete checkout automation. BigCommerce Testing Stack BigCommerce has a different architecture from WooCommerce or Magento: * Management API — REST API for products,
Security Testing
Semgrep is a fast, language-agnostic static analysis tool that finds security vulnerabilities by pattern matching against source code. It ships with thousands of community rules for OWASP Top 10 vulnerabilities, secret detection, and language-specific security patterns. You can also write custom rules in YAML to catch patterns specific to your
Fuzz Testing
Hypothesis is the most accessible entry point to property-based and fuzz testing for Python developers. Unlike AFL++ or libFuzzer which require C/C++ code and complex toolchains, Hypothesis works with any Python function, integrates with pytest, and produces minimal counterexamples automatically. It's been finding real bugs in production
Fuzz Testing
Go 1.18 shipped something remarkable: built-in fuzz testing integrated directly into go test. No external tools, no compilation flags, no special setup — just write a FuzzXxx function and run go test -fuzz. This guide covers native Go fuzzing, the older dvyukov/go-fuzz library, and how to write fuzz targets
Fuzz Testing
Heartbleed. Log4Shell. The Stagefright vulnerability. A disproportionate number of the most severe security vulnerabilities in recent history share one thing in common: they would have been caught by a fuzzer. Fuzz testing — fuzzing — is one of the most effective bug-finding techniques ever discovered, yet most development teams never use it.
Fuzz Testing
Rust's memory safety guarantees eliminate an entire class of bugs that make fuzzing critical in C/C++ — but Rust code can still have logic errors, integer overflows, panics, and unexpected behavior. cargo-fuzz brings libFuzzer to Rust with a clean command-line interface, and the arbitrary crate enables structured fuzzing
Testing
SonarQube and CodeClimate are both code quality platforms, but they serve different teams. SonarQube is deeper and more configurable for enterprise; CodeClimate is simpler, faster to adopt, and better integrated with GitHub. This guide compares them across features, CI integration, and team fit. Overview Both tools analyze code for quality
Testing
Magento 2 has a built-in test framework covering unit tests, integration tests, and functional tests via MFTF (Magento Functional Testing Framework). This guide covers each layer with practical examples — from isolated PHP unit tests to full browser checkout flows. Magento 2 Test Architecture Magento 2 ships with four test types:
Security Testing
SAST (Static Application Security Testing) analyzes source code without running it. DAST (Dynamic Application Security Testing) tests the running application by sending malicious inputs. SAST finds vulnerabilities early in development; DAST finds vulnerabilities that only appear at runtime. Use both: SAST in CI on every pull request, DAST against a
