How to convert bason to json(with src)?

[Alex Luya]

What I really want to do is hide mongdb connections stuffs(creation,clone..close) and error handling stuff like this:

func ExcuteQuery(collection string, query interface{}) []byte {
ses := ensureMongoConnection("ExcuteQuery")
defer ses.Close()

var result []interface{}
err := ses.DB(databaseName).C(collection).Find(query).All(&result)
if err != nil {
  panic(err)
}

// check err
rawjson, err := json.Marshal(result)
// return result
if err != nil {
  panic(err)
}
return rawjson
}

And test caller will like this:

func (s *MySuite) TestGetModel(c *C) {
res := mgd.ExcuteQuery(collection, nil)
//************************************here something get printed out***********************************
fmt.Println(res)
var list []MySuite
json.Unmarshal(res, list)
//************************************but why here is length of list 0?***********************************
c.Check(list[0].Value, Equals, value)
}

Alex, please use a pastebin in the future, such as gist.github.com,
rather than pasting a lot of code inline.

Also, sample files should be self contained so we can run them, since
otherwise we'll have to do guess work just to get your stuff running.

This should be &list. Check the error result.
