Theory learned

QA Engineer role in product teams; QA roles/titles and career paths
ISTQB CTFL fundamentals: purpose + exam format; core testing principles; test closure/sign-off mindset
SDLC overview; software management goals; Waterfall vs Agile; methodology/model vs framework
Scrum (ceremonies, sprints, refinement), Kanban (flow, WIP), XP practices (TDD, CI, refactoring, pair programming, etc.), hybrid approaches
Testing vs QA/QE; STLC activities across lifecycle; regulated/compliance-driven QA concepts
Testing environments (local/DEV/QA/Staging/UAT/Prod) + post-release validation; cache/cookies impacts
Manual testing foundations: black-box/white-box/gray-box; when manual vs automation; exploratory mindset
Automation testing foundations: static vs dynamic testing; reviews + static analysis; what/how/when to automate; frameworks vs tools; low-code/no-code; CI/CD alignment; limitations
Testing levels (unit, integration, system, system integration, acceptance) and test types (functional vs non-functional)
Change-related testing: confirmation (re-test), regression testing, impact analysis
Test design techniques: Equivalence Partitioning (EP), Boundary Value Analysis (BVA), decision tables, state transitions; white-box coverage (statement/branch); experience-based (exploratory, error guessing, checklist)
Test documentation: test plan, test suite, test cases; Gherkin/BDD (Given–When–Then); regression planning and prioritization
Defect management: error/defect/failure; defect lifecycle; root-cause thinking; defect metrics (density, severity distribution, leakage/escape, DRE, reopen rate, MTTD/MTTR, etc.)
ALM fundamentals and why it matters; Jira vs Confluence roles in delivery governance and traceability
Backend testing foundations: databases/DBMS; relational vs NoSQL; SQL basics; CRUD; constraints (PK/FK/UNIQUE/NOT NULL/CHECK/DEFAULT); ACID; DB performance risk awareness
API testing foundations: REST, endpoints/resources, HTTP methods, requests/responses, headers/params/body, JSON; API types; API key/credential security awareness
Non-functional testing foundations: responsive/mobile/cross-device; security awareness (phishing); performance testing types (load/stress/spike/soak/scalability) + key metrics
Career development: LinkedIn profile structure, core values, elevator pitch (Past–Present–Future), networking/job search and Boolean logic
AI in testing: LLM/GenAI basics (tokens, embeddings, context windows, non-determinism, multimodal); agents vs agentic AI; using AI across the test lifecycle; testing AI risks (hallucinations, bias, long-context degradation)

Skills acquired

QA / Quality Engineering mindset (quality ownership, shift-left prevention, risk-based thinking, user-centric validation, evidence-based decisions)
Manual testing execution using black-box testing, white-box testing, and gray-box testing, plus exploratory testing and checklist-based testing
Test design with Equivalence Partitioning, Boundary Value Analysis, Decision Table Testing, State Transition Testing, Statement Testing, Branch Testing, and Error Guessing
Testing strategy selection by testing levels (component/unit, integration, system, system integration, acceptance) and test types (functional and non-functional), including confirmation testing (re-testing fixes) and regression testing
Professional test documentation: Test Plans, Test Suites, Test Cases, and Gherkin / Behavior-Driven Development (Given–When–Then) for clear, automation-ready scenarios
Defect management: high-quality bug reporting (steps, expected vs actual, environment, severity/priority, evidence) + defect lifecycle handling and defect metrics interpretation
Automation fundamentals: deciding what to automate, exposure to unit testing, integration testing, API testing, user interface testing, smoke testing, regression testing, and CI/CD execution mindset
API integration testing: REST requests (GET/POST/PUT/DELETE), headers/params/body, JSON validation, collections/runs, basic assertions
Backend testing with Structured Query Language: querying/filtering + CRUD validation, integrity via constraints (Primary Key, Foreign Key, Unique, Not Null, Check, Default) and ACID awareness
Non-functional readiness: responsive and cross-device testing, baseline security awareness (phishing/credential hygiene), and performance testing literacy (load testing, stress testing, spike testing, endurance (soak) testing, scalability testing)
ALM delivery workflows: traceability, dashboards/filters/queries, documentation, QA sign-off and post-deployment verification readiness
AI-enabled QA productivity: GenAI for test cases/data/analysis/reporting, understanding reliability limits (context windows, non-determinism, hallucinations), plus agents vs agentic AI awareness
Career readiness: LinkedIn optimization, elevator pitch, interview practice, targeted job search and networking execution
