Unit Test with dump from mongodump about fongo

[twillouer]

Hi,

perhaps you can use com.mongodb.DefaultDBDecoder do to this ?

I can integrate this in FongoRule if your test is good

I messed around with org.bson.BSON (which uses DefaultDBDecoder I guess) as well as com.mongodb.util.JSON but without success.

With org.bson.BSON you get something like a DBObject which can then be inserted in a collection, unfortunately it is getting inserted as one document instead of 18 which are in my bson dump.

When exporting json with some script (in mongo printJson(doc)) it is not deserializeable with JSON.deserialize due to ObjectID and dates I have in that document.

I came up with a more or less workaround:

Export Data from Live DB:

BasicDBObject query = new BasicDBObject();
        query.put("destination", "OSL");
        query.put("hotel", 140423);
        DBCursor result = this.mongo.getDB("DB").getCollection("collectionName").find(query);
        while (result.hasNext()) {
            DBObject current = result.next();
            Object id = current.get("_id");
            FileUtils.write(new File("/myPath/" + id), JSON.serialize(current));
        }
        result.close();

Then importing into fongo like this:

        File f = new File(ClassUtils.getDefaultClassLoader().getResource("pathInProject").toURI());
        for (File f2 : f.listFiles()) {
            DBObject dbObject = (DBObject) JSON.parse(new String(Files.readAllBytes(Paths.get(f2.toURI()))));
            collection.insert(dbObject);
        }

Maybe in the near future I will be able to import a bson dump itself but as I googled there were no options available in the Java Driver (you will find serveral similar requests)

Maybe this is also the reson why in tools like robomongo there is no Export/Import function.
