What is Behavior-Driven Development (BDD)?
Behavior-Driven Development extends TDD by writing tests in plain language that describes user behavior, enabling collaboration between developers, testers, and business stakeholders.
What is End-to-End Testing?
End-to-end testing validates complete user workflows through the full application stack, from UI interactions through APIs and databases, ensuring the entire system works together.
What is Integration Testing?
Integration testing validates that multiple components, services, or systems work correctly together, catching bugs that unit tests cannot find in isolated code.
What is Penetration Testing?
Penetration testing simulates real-world attacks against a system to identify exploitable vulnerabilities before malicious actors do, validating security controls through adversarial testing.
What is Performance Testing?
Performance testing measures how a system behaves under load, identifying bottlenecks, scalability limits, and degradation points before they affect production users.
What is Regression Testing?
Regression testing verifies that previously working functionality has not been broken by new code changes, protecting existing behavior throughout the development lifecycle.
What is Smoke Testing?
Smoke testing runs a quick subset of critical tests to verify a build is stable enough for further testing, catching catastrophic failures fast without running the full test suite.
What is Test-Driven Development (TDD)?
Test-Driven Development is a software development practice where tests are written before production code, driving design through short red-green-refactor cycles.
What is Unit Testing?
Unit testing validates individual functions and components in isolation to verify they behave correctly, providing fast feedback and a safety net for refactoring.
White-Box vs Black-Box Testing: What's the Difference?
White-box testing uses knowledge of internal code to design tests. Black-box testing treats software as opaque and tests only inputs and outputs. Both approaches are essential.
