Test Strategy
// Definition
The high-level, organisation-wide approach to testing — what gets tested, by whom, with what tools, at what stage. Broader and more permanent than a test plan.

Test Plan
A document describing the scope, approach, schedule, resources, and deliverables for testing a release or feature. Narrower and more time-bound than a test strategy.
Test Pyramid
A model for balancing test types: a wide base of fast unit tests, a smaller layer of integration tests, and a thin layer of slow end-to-end tests. Counters the inverted 'ice-cream cone' anti-pattern of UI-heavy suites.
STLC (Software Testing Life Cycle)
The structured phases of testing: requirement analysis, test planning, test design, environment setup, execution, and closure. Mirrors the SDLC at the testing layer.
