Course Overview
- This comprehensive course is expertly crafted to transform aspiring and current QA professionals into formidable SDET candidates, ready to conquer the most challenging interviews at top tech companies.
- Delve deep into the critical intersection of software development and quality assurance, focusing on architecting, building, and maintaining scalable, robust test automation frameworks from an engineering perspective.
- Explore a carefully curated curriculum addressing fundamental data structures, algorithms, and advanced coding challenges specifically relevant to the SDET role, emphasizing efficient and testable code.
- Gain profound insights into system design principles for testing, including considerations for microservices, performance, security, and seamless integration within modern CI/CD pipelines.
- Develop not just technical prowess but also master the art of effective communication, enabling you to articulate complex ideas clearly and confidently during technical discussions and behavioral assessments.
Requirements / Prerequisites
- Foundational Programming Knowledge: A basic understanding of at least one object-oriented programming language (e.g., Java, Python, C#) is crucial for engaging with coding and framework implementations.
- Basic Software Testing Concepts: Familiarity with general testing principles, methodologies (Agile), and the software development lifecycle (SDLC) provides a vital groundwork for advanced topics.
- Commitment to Practice: Success hinges on consistent dedication to solving coding problems, implementing automation scenarios, and participating in mock interview drills.
Skills Covered / Tools Used
- Advanced Test Automation Frameworks: Master industry-standard tools like Selenium WebDriver, Playwright, or Cypress for UI automation, along with Page Object Model (POM) architectures and Behavior-Driven Development (BDD) using Cucumber/Gherkin.
- API Testing Expertise: Develop proficiency in testing RESTful APIs using libraries such as RestAssured (Java) or Requests (Python), and leverage tools such as Postman for comprehensive backend validation.
- Core Programming & Data Structures: Solidify your understanding of essential data structures (arrays, lists, maps, trees) and algorithms (sorting, searching) with practical application in test engineering and problem-solving.
- Object-Oriented Design (OOD) & Design Patterns: Apply OOD principles and common design patterns (e.g., Factory, Singleton) to build modular, scalable, and maintainable test automation codebases.
- System Design for Testability: Learn to design robust, scalable, and resilient test systems from scratch, incorporating microservices architecture, distributed systems, and effective data management strategies for testing.
- CI/CD Integration & DevOps: Gain hands-on experience integrating automation scripts into Continuous Integration/Continuous Deployment (CI/CD) pipelines using tools like Jenkins, GitHub Actions, or GitLab CI.
- Containerization with Docker: Understand how to containerize test environments and applications using Docker, ensuring consistent, isolated, and reproducible test execution across various platforms.
- Database Testing & SQL: Acquire skills in writing SQL queries to validate data integrity, state transitions, and consistency across various relational and NoSQL databases, crucial for full-stack testing.
