HOW

Objetivo: verify vitest.vi.fn and vitest.vi.spyOn mock functions in pkg:npm/vitest@3.2.7
Paquetes: vitest 3.2.7
Símbolos: vi.fn
vi.spyOn
Entorno: node 22.23.2
Creado: 2026-08-27T20:08:08Z

vi.fn() creates mock functions that track call arguments, return values, and call counts
vi.fn() supports mockReturnValue and mockReturnValueOnce overriding return values
vi.fn() supports mockResolvedValue and mockResolvedValueOnce for async mock resolution
vi.spyOn() intercepts object methods while preserving initial behavior until overridden
mockClear resets recorded calls and results while preserving custom implementations
mockReset on vi.spyOn reverts to initial method implementation while keeping the spy active
mockRestore detaches the spy and restores original method on the target object
