Quiz
AI Agent Testing: Multi-Step Reasoning, Tool Calls & Trajectory Evaluation
Test your understanding of agentic AI systems — how they differ from standard LLM calls, what makes them risky, and how QA engineers validate tool calls and agent trajectories.
Quiz
RAG Pipeline Testing: Retrieval Accuracy, Chunking & Hallucination Prevention
Learn to evaluate Retrieval-Augmented Generation systems end-to-end — chunk quality, embedding search, RAGAS metrics, and strategies for preventing retrieval-caused hallucinations.
Quiz
AI Hallucination & Bias Detection: Testing LLM Reliability and Fairness
Learn to detect, measure, and mitigate LLM hallucinations and bias. Topics include sycophancy, calibration, demographic parity, and practical evaluation techniques for production AI.
Quiz
Playwright AI Test Automation: MCP Integration, Route Mocking & Auto-Wait
Advance your Playwright skills for AI-era test automation — MCP browser control, route interception, auto-waiting behavior, and writing resilient selectors that survive UI changes.
Quiz
API Contract Testing with Pact: Consumer-Driven Contracts for Microservices
Learn consumer-driven contract testing with Pact. Covers pact files, the Pact Broker, can-i-deploy, and when contract testing beats shared integration environments.
Quiz
OWASP API Security Top 10: Testing Authentication, Authorization & Injection
Learn to test the OWASP API Security Top 10 — BOLA, mass assignment, BFLA, rate limiting, and broken authentication. Essential knowledge for security-aware QA engineers.
Quiz
GraphQL API Testing: Queries, Mutations, Introspection & N+1 Detection
Master GraphQL-specific testing challenges — schema introspection, mutation validation, N+1 query detection, error format differences from REST, and security considerations.
Quiz
k6 Performance Testing: Virtual Users, Thresholds & Load Scenarios
Learn k6 fundamentals for modern performance testing — virtual users, ramp-up strategies, p95 latency, threshold-based pass/fail, and how k6 compares to JMeter.
Quiz
pytest Advanced: Fixtures, Parametrize, conftest & Parallel Execution
Level up your pytest skills — fixture scopes, parametrize for data-driven tests, conftest.py discovery, pytest-xdist parallel execution, and xfail/skip markers.
Quiz
Visual Regression Testing: Playwright Snapshots, Percy & CI/CD Challenges
Learn visual regression testing strategies — what it catches that functional tests miss, how Playwright's toHaveScreenshot works, AI-powered diff tools, and CI rendering pitfalls.
Quiz
WCAG 2.1 Accessibility Testing: axe-core, Screen Readers & Keyboard Navigation
Learn to test web accessibility using WCAG 2.1 standards — understand Level A vs AA vs AAA, automate with axe-core in Playwright, and find the defects only manual testing catches.
Quiz
GitHub Actions for QA: Quality Gates, Matrix Strategy & Flaky Test Management
Build robust CI/CD quality gates with GitHub Actions — jobs vs steps, reusable workflows, matrix strategy for cross-browser testing, and strategies for taming flaky tests.
Quiz
Exploratory Testing: Session-Based Techniques, Charters & SFDPOT Heuristic
Master exploratory testing — how it differs from scripted testing, session-based test management, SFDPOT and other heuristics, and what defects only exploratory testing finds.
Quiz
Appium Mobile Test Automation: iOS, Android & Cross-Platform Strategies
Test your Appium knowledge — desired capabilities, locator strategies, real device vs emulator trade-offs, and the Appium 2.0 driver architecture for iOS and Android automation.
Quiz
JMeter Performance Testing: Thread Groups, Ramp-Up, Distributed Load & Listeners
Master Apache JMeter — Thread Groups, Constant Timers, ramp-up configuration, distributed test execution, and best practices for using JMeter in CI/CD pipelines.
Quiz
Data Quality & ETL Testing: Data Contracts, Great Expectations & Pipeline Validation
Learn to test data pipelines end-to-end — ETL stage validation, data contracts, Great Expectations for automated quality assertions, uniqueness, completeness, and referential integrity.
