**A simple fake clock for Go.**
## Usage
Replace uses of the `time` package with the `clockwork.Clock` interface instead.
For example, instead of using `time.Sleep` directly:
```go
func myFunc() {
time.Sleep(3 * time.Second)
doSomething()
}
```
Inject a clock and use its `Sleep` method instead:
```go
func myFunc(clock clockwork.Clock) {
clock.Sleep(3 * time.Second)
doSomething()
}
```
Now you can easily test `myFunc` with a `FakeClock`:
```go
func TestMyFunc(t *testing.T) {
c := clockwork.NewFakeClock()
// Start our sleepy function
var wg sync.WaitGroup
wg.Add(1)
go func() {
myFunc(c)
wg.Done()
}()
// Ensure we wait until myFunc is sleeping
c.BlockUntil(1)
assertState()
// Advance the FakeClock forward in time
c.Advance(3 * time.Second)
// Wait until the function completes
wg.Wait()
assertState()
}
```
and in production builds, simply inject the real clock instead:
```go
myFunc(clockwork.NewRealClock())
```
See [example_test.go](example_test.go) for a full example.
