Clock is a small library for mocking time in Go. It provides an interface
|
|
around the standard library's [`time`][time] package so that the application
|
|
can use the realtime clock while tests can use the mock clock.
|
|
|
|
The module is currently maintained by @djmitche.

|

|
## Usage
|
|
|
|
### Realtime Clock
|
|
|
|
Your application can maintain a `Clock` variable that will allow realtime and
|
|
mock clocks to be interchangeable. For example, if you had an `Application` type:
|
|
|
|
```go
|
|
import "github.com/benbjohnson/clock"
|
|
|
|
type Application struct {
|
|
Clock clock.Clock
|
|
}
|
|
```
|
|
|
|
You could initialize it to use the realtime clock like this:
|
|
|
|
```go
|
|
var app Application
|
|
app.Clock = clock.New()
|
|
...
|
|
```
|
|
|
|
Then all timers and time-related functionality should be performed from the
|
|
`Clock` variable.
|
|
|
|
|
|
### Mocking time
|
|
|
|
In your tests, you will want to use a `Mock` clock:
|
|
|
|
```go
|
|
import (
|
|
"testing"
|
|
|
|
"github.com/benbjohnson/clock"
|
|
)
|
|
|
|
func TestApplication_DoSomething(t *testing.T) {
|
|
mock := clock.NewMock()
|
|
app := Application{Clock: mock}
|
|
...
|
|
}
|
|
```
|
|
|
|
Now that you've initialized your application to use the mock clock, you can
|
|
adjust the time programmatically. The mock clock always starts from the Unix
|
|
epoch (midnight UTC on Jan 1, 1970).
|
|
|
|
|
|
### Controlling time
|
|
|
|
The mock clock provides the same functions that the standard library's `time`
|
|
package provides. For example, to find the current time, you use the `Now()`
|
|
function:
|
|
|
|
```go
|
|
mock := clock.NewMock()
|
|
|
|
// Find the current time.
|
|
mock.Now().UTC() // 1970-01-01 00:00:00 +0000 UTC
|
|
|
|
// Move the clock forward.
|
|
mock.Add(2 * time.Hour)
|
|
|
|
// Check the time again. It's 2 hours later!
|
|
mock.Now().UTC() // 1970-01-01 02:00:00 +0000 UTC
|
|
```
|
|
|
|
Timers and Tickers are also controlled by this same mock clock. They will only
|
|
execute when the clock is moved forward:
|
|
|
|
```go
|
|
mock := clock.NewMock()
|
|
count := 0
|
|
|
|
// Kick off a timer to increment every 1 mock second.
|
|
go func() {
|
|
ticker := mock.Ticker(1 * time.Second)
|
|
for {
|
|
<-ticker.C
|
|
count++
|
|
}
|
|
}()
|
|
runtime.Gosched()
|
|
|
|
// Move the clock forward 10 seconds.
|
|
mock.Add(10 * time.Second)
|
|
|
|
// This prints 10.
|
|
fmt.Println(count)
|
|
```
