Overview

Package clock is the canonical injected-dependency example (ADR-0002). It provides the Clock interface so components can be tested with a deterministic fake instead of wall-clock time.

Types

type Clock 

type Clock interface {
	Now() time.Time
}

Clock is the port for time operations. Components depend on this interface; the app injects System() in production and a Fake in tests.

func Fake 

func Fake(t time.Time) Clock

Fake returns a clock fixed at the given time — useful for deterministic tests.

func System 

func System() Clock

System returns the real-time clock.

type Manual added in v0.2.5 

type Manual struct {
	// contains filtered or unexported fields
}

Manual is a fake clock that stands still until Advance moves it, for tests of time-bounded behavior. Safe for concurrent use.

func NewManual added in v0.2.5 

func NewManual(t time.Time) *Manual

NewManual returns a Manual clock standing at t.

func (*Manual) Advance added in v0.2.5 

func (m *Manual) Advance(d time.Duration)

Advance moves the clock forward by d.

func (*Manual) Now added in v0.2.5 

func (m *Manual) Now() time.Time

Now returns the clock's current time.
