Knowledge of Embedded Domain Testing and Web Domain Testing

1. Embedded Domain Testing

• Overview: Embedded systems are specialized computer systems designed to perform specific functions within larger systems or devices. Testing embedded systems involves verifying their functionality, performance, reliability, and compatibility with hardware components.
• Challenges: Testing embedded systems poses unique challenges due to limited resources, real-time constraints, hardware dependencies, firmware interactions, and safety-critical requirements.
• Testing Techniques: Familiarize with testing techniques specific to embedded systems, such as black-box testing, white-box testing, boundary value analysis, stress testing, performance testing, hardware-in-the-loop (HIL) testing, and software-in-the-loop (SIL) testing.
• Tools and Simulators: Gain experience with tools and simulators used for embedded system testing, such as JTAG debuggers, oscilloscopes, logic analyzers, emulators, and simulators like QEMU, Proteus, or Simulink.
• Standards and Compliance: Understand industry standards and compliance requirements for embedded systems testing, such as ISO 26262 for automotive, DO-178C for aerospace, IEC 61508 for industrial control systems, and FDA regulations for medical devices.

2. Web Domain Testing

• Overview: Web domain testing focuses on testing web applications, websites, and web services to ensure their functionality, usability, performance, security, and compatibility across browsers and devices.
• Types of Testing: Master various types of web testing, including functional testing (smoke testing, regression testing, integration testing), non-functional testing (performance testing, security testing, usability testing), compatibility testing, and cross-browser testing.
• Testing Tools: Gain proficiency in web testing tools and frameworks like Selenium WebDriver, Cypress, Puppeteer, JMeter, LoadRunner, OWASP ZAP, Burp Suite, and tools for API testing like Postman or SOAPUI.
• Browser Dev Tools: Utilize browser developer tools (Chrome DevTools, Firefox Developer Tools, etc.) for debugging, performance profiling, network monitoring, and inspecting web elements during testing.
• Accessibility Testing: Understand accessibility testing principles and tools (e.g., Axe, Wave, Lighthouse) to ensure web applications comply with accessibility standards (WCAG) and are usable by people with disabilities.
• Security Testing: Familiarize with security testing techniques like penetration testing, vulnerability scanning, security headers analysis, secure coding practices, and compliance with security standards (OWASP Top 10, PCI DSS, GDPR).

Master Black Box, White Box, and Gray Box Testing

1. Black Box Testing: Focus on understanding requirements, creating comprehensive test cases, prioritizing boundary and equivalence classes, and emphasizing functional testing without knowledge of internal code structures.
2. White Box Testing: Highlight knowledge of code structures, algorithms, and system architecture, and demonstrate expertise in unit testing, code coverage analysis, path testing, and integration testing strategies.
3. Gray Box Testing: Showcase skills in combining black box and white box techniques, emphasizing scenario-based testing, data-driven testing, and utilizing limited knowledge of internal workings to design effective test cases.
