## LogAdapter
This repo is a adapter to the package [nuveo/log](github.com/nuveo/log) that uses Golang's standard `log` instead of `fmt` package to write into stdout. This is useful for testing if a application logged something by setting the log to a buffer.
## [Testing logs with this adapter](https://stackoverflow.com/questions/44119951/how-to-check-a-log-output-in-go-test)
```go
package main
import (
"bytes"
"fmt"
"io"
"os"
"testing"
l "log"
"github.com/nuveo/log"
la "github.com/arxdsilva/logAdapter"
)
func readByte() {
// force an error
err := io.EOF
if err != nil {
log.Println("Couldn't read first byte")
}
}
func TestReadByte(t *testing.T) {
// remove std adapter
// this prevents double logging
log.RemoveAdapter("stdout")
log.AddAdapter("adapter", log.AdapterPod{Adapter:la.LogAdapter, Config: nil})
var buf bytes.Buffer
l.SetOutput(&buf)
defer func() {
l.SetOutput(os.Stderr)
}()
readByte()
// do something with the logs
t.Log(buf.String())
}
```
