What This Course Covers

UI Automation Mastery

• Handling flaky dynamic elements with explicit and fluent Selenium waits.
• Crafting end‑to‑end Cypress tests that intercept network requests for reliable verification.
• Managing Playwright contexts for multi‑browser parallel execution.
• Building a maintainable page‑object model that scales across large web applications.

These lessons push you beyond basic click‑and‑type scripts, preparing you for the complex front‑end challenges presented in top‑tech interviews.

API Testing & Security

• Implementing OAuth 2.0 authentication flows in Postman and REST Assured.
• Designing JSON Schema contracts and validating responses against them.
• Creating data‑driven collections that iterate over thousands of test cases automatically.
• Securing API endpoints by testing for common vulnerabilities such as injection and broken authentication.

By the end of this module you’ll be able to prove API reliability and security—key criteria for SDET hiring managers.

Performance & Load Testing

• Configuring JMeter thread groups for realistic user‑load simulations.
• Writing k6 scripts to perform spike, stress, and soak testing on micro‑services.
• Analyzing performance metrics to identify CPU, memory, and I/O bottlenecks.
• Reporting findings with Grafana dashboards that integrate into CI pipelines.

Performance testing knowledge differentiates a competent tester from a true performance‑aware engineer.

QA Strategy & Architecture

• Applying the Test Pyramid to balance unit, integration, and UI tests efficiently.
• Practicing Shift‑Left testing to catch defects early in the development lifecycle.
• Using Behavior‑Driven Development (BDD) to align test cases with business requirements.
• Integrating automated suites into Jenkins, GitHub Actions, or Azure DevOps pipelines for continuous delivery.

This strategic layer equips you to design test frameworks that survive scaling, refactoring, and rapid release cycles.
