### 单元测试文档
#### 样例
```go
package dao
import (
"testing"
_ "gitee.com/timedb/wheatCache/conf"
"gitee.com/timedb/wheatCache/pkg/lru"
"gitee.com/timedb/wheatCache/pkg/proto"
"github.com/stretchr/testify/require"
)
// 规范1. 每个 package 应该都至少有一个单测
// 规范2. 包里有公用的 mock 数据应该分离出来。
func mockData(t *testing.T, d *Dao) {
values := []string{"1", "1.3", "abcdefg"}
for _, val := range values {
key := &proto.BaseKey{
Key: val,
}
_, err := d.Set(key, val)
// 规范3. 使用 require 包来完成单测
require.NoError(t, err)
}
}
// 规范4. 单元测试应该尽可能覆盖全部情况,不要使用依赖注入。
func TestDao_Reduce(t *testing.T) {
lruCache := lru.NewLRUCache()
dao := NewDao(lruCache)
mockData(t, dao)
resp, err := dao.Reduce(&proto.BaseKey{Key: "1"}, 2)
require.NoError(t, err)
require.Equal(t, resp, "-1")
resp, err = dao.Reduce(&proto.BaseKey{Key: "1.3"}, 2)
require.NoError(t, err)
require.Equal(t, resp, "-0.70")
_, err = dao.Reduce(&proto.BaseKey{Key: "abcdefg"}, 2)
require.Error(t, err)
}
