QA Career
The QA engineering career has more defined progression levels than many people realize when they enter the field. Understanding what distinguishes each level helps you set realistic goals and know what to develop next. The Career Ladder Level Typical Years Experience Focus Junior QA Engineer 0–2 years Execution, learning

Compensation for QA engineers varies widely — sometimes a 2x or 3x difference between similar roles based on company type, location, and specialization. This guide provides concrete salary data and the factors that drive the largest compensation differences. Note: All figures are estimates based on publicly available data from Glassdoor, Levels.

The ISTQB Certified Tester Foundation Level (CTFL) is the most widely recognized entry-level testing certification in the world. Over 1.2 million exams have been taken globally. But is it worth pursuing in 2025? And if you decide to go for it, how do you actually pass? This guide covers
QA Career
Quality assurance engineering is one of the most accessible entry points into tech. You don't need a computer science degree, and many QA engineers come from completely unrelated backgrounds. But the path is more specific than "just learn to test." This guide maps the realistic journey.
Testing
Ansible playbooks are often "tested" by running them against production and hoping. Molecule changes that — it provides a framework for testing roles and playbooks in isolated containers or VMs, verifying your automation actually works before it touches real infrastructure. What Is Molecule? Molecule is the official testing framework
Testing
Infrastructure-as-Code introduced a new class of bug: the infrastructure configuration error. A missing variable, a wrong CIDR block, or an IAM permission misconfiguration can take down a service just as effectively as a software bug. Testing your Terraform code prevents these failures. This guide covers the full Terraform testing stack:
Testing
Policy-as-code turns compliance requirements into machine-checkable rules. Instead of "all S3 buckets must have versioning enabled" living only in a wiki, it lives in code that runs in your CI pipeline and blocks non-compliant deployments automatically. Open Policy Agent (OPA) is the most widely adopted policy-as-code engine. conftest

Pulumi brings real programming languages to infrastructure — TypeScript, Python, Go, C#. With that comes a genuine testing story: unit tests that mock the cloud provider and integration tests that deploy to a real environment. Pulumi's Testing Model Pulumi provides two distinct testing approaches: Unit testing — uses the Pulumi
Testing
GitOps treats infrastructure like application code: changes go through pull requests, get reviewed, pass CI, and deploy automatically. But infrastructure PRs need different validation than application PRs. A bad dependency upgrade might break a test; a bad Terraform change might delete your database. This guide covers how to build CI/
QA Career
Three certifications dominate the QA field: ISTQB's CTFL, the CSTE, and the CAST. They have different origins, different audiences, and different levels of market recognition. Here's how they compare. Quick Overview Certification Full Name Body Level Focus ISTQB CTFL Certified Tester Foundation Level International Software Testing

AWS CDK (Cloud Development Kit) lets you define AWS infrastructure with TypeScript, Python, Java, or Go. Because CDK produces CloudFormation templates, testing means asserting on the generated template — and CDK provides a first-class testing library for exactly this. CDK Testing Philosophy CDK tests don't deploy real infrastructure during

Compose Multiplatform extends Jetpack Compose beyond Android, bringing the same declarative UI model to iOS, desktop (macOS, Windows, Linux), and web. But testing a UI that runs on four platforms is a different challenge than testing a single-platform app. This guide covers how to write and run Compose Multiplatform UI
