Lecture 48: Equivalence Class Testing - I
In this lecture, we delve into Equivalence Class Testing (ECT), a fundamental method in black-box testing aimed at verifying functional requirements without needing access to or knowledge of the internal code structure of the software. ECT operates on the premise that it's not necessary to test every single input value, but rather to categorize inputs based on equivalence classes, where all values within a class are expected to yield identical processing results.
Core Concepts:
- Black-Box Testing: This testing methodology assesses the functionality of the software purely from an external viewpoint β inputs are given, and responses are analyzed without concern for how outcomes are achieved internally. It's critical for confirming that a software component behaves as intended.
- Equivalence Class Testing (ECT): This technique systematically partitions the input domain into subsets, termed equivalence classes. Each class contains inputs expected to be processed in the same manner by the software. The central concept of ECT is the
