📖 What is Software Development Lifecycle (SDLC)?

The Software Development Lifecycle (SDLC) is a conceptual framework describing all activities in a software development project from initial planning to retirement. It provides structure to the development process by defining phases such as requirements analysis, design, coding, testing, and deployment.

🥋 Sensei Says:

"Understand that testing activities should be integrated throughout the entire SDLC, not just at the end. The ISTQB exam frequently tests your knowledge of how testing fits into different SDLC models."

Equivalence Partitioning vs Boundary Value Analysis: ISTQB

Equivalence Partitioning (EP) divides input data into groups that should be processed identically, reducing test cases by testing one representative value per group. Boundary Value Analysis (BVA) complements this by testing the edges of these partitions, where defects frequently occur, ensuring the system handles limits and transitions correctly.
