我正在尝试存根os.Stat
并ioutil.ReadFile(path)
使用下面的代码,或者如果您喜欢在 go playground [1]
package main
import (
"fmt"
"io/ioutil"
"os"
"strings"
)
func AssignFileValueFrom(path string, val *string) {
var (
tempValue []byte
err error
)
if _, err = os.Stat(path); err == nil {
if err != nil {
fmt.Println("There was a os stat error:", err)
}
tempValue, err = ioutil.ReadFile(path)
if err != nil {
fmt.Println("There was an io read error:", err)
}
*val = strings.TrimSpace(string(tempValue))
}
}
我已经使用了 testify 并尝试按照此处的示例 [2]
package main
import (
"testing"
"github.com/stretchr/testify/mock"
)
type osMock struct {
mock.Mock
}
func (o osMock) Stat(path string) (interface{}, error) {
return nil, nil
}
func TestAssignFileValueFrom(t *testing.T) {
var test string
osm := new(osMock)
osm.On(`Stat`, `./.test`).Return([]byte(`1`), nil)
AssignFileValueFrom(`./.test`, &test)
// assert.Equal(t, `1`, test)
osm.AssertExpectations(t)
}
我做错了什么?
