Frequently Asked Questions
Who is this course for?
All levels. Considering QA as a career — start with Module 0. Manual tester wanting automation — jump to Module 8. Senior aiming for Lead — Module 12. Each module is self-contained, start anywhere.
Do I need programming experience?
No. Modules 0–4 are fully conceptual: testing fundamentals, test design techniques, documentation. Programming starts in Module 8, which includes a dedicated lesson on programming fundamentals for testers from scratch.
How is this different from QA Bible, Halushka, Guru99?
Coverage. QA Bible covers ~120 topics, Halushka 24. This course has 320 lessons across 12 modules, including 24 topics no one else covers: AI/ML testing, Playwright, contract testing, chaos engineering, gRPC, career growth to Director. Plus hands-on exercises and quizzes in every lesson.
Why is the entire course free?
I believe quality QA education shouldn't be behind a paywall. This course is the result of 7+ years of experience at Google, AI startups, and fintech. It's free because the best way to build authority in the industry is to share knowledge openly.
How long does it take to complete?
80+ hours of content. At your own pace — typically 3–6 months at 2–3 lessons per day. Each lesson is designed for one sitting: 15–55 minutes. Go linearly or jump to specific topics.
What languages is the course available in?
English, Spanish, and Russian. All 320 lessons are fully available in three languages. Not machine translation — each version is adapted with terminology and context relevant to the QA community in that language.
Are there hands-on exercises?
Yes. 150+ exercises with hints and solutions. Quizzes in every lesson to check understanding. Final assessment at the end of each module. Mermaid diagrams and syntax-highlighted code examples.
Can I use this to prepare for ISTQB certification?
Yes. Modules 1–4 cover the entire ISTQB Foundation Level syllabus: testing principles, STLC, test design techniques, documentation. Module 12 includes a dedicated lesson on ISTQB certifications with preparation recommendations.
