@ -440,21 +440,23 @@ Logrus has a built in facility for asserting the presence of log messages. This
* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
```go
import (
"testing"
import(
"github.com/sirupsen/logrus"
"github.com/sirupsen/logrus/hooks/null"
"github.com/stretchr/testify/assert"
"testing"
)
func TestSomething(t *testing.T) {
func TestSomething(t*testing.T){
logger, hook := null.NewNullLogger()
logger.Error("Hello error")
logger.Error("Helloerror")
assert.Equal(1, len(hook.Entries))
assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level)
assert.Equal("Hello error", hook.LastEntry().Message)
assert.Equal(t, 1, len(hook.Entries))
assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level)
assert.Equal(t, "Helloerror", hook.LastEntry().Message)
hook.Reset()
assert.Nil(hook.LastEntry())
assert.Nil(t, hook.LastEntry())
}
```
