* Test to ensure that (dump/restore/export/import/oplog) works with a replica set connection string
|
|
* 1. Start a replica set.
|
|
* 2. Add data to a collection.
|
|
* 3. Take a dump of the database.
|
|
* 4. Drop the db.
|
|
* 5. Restore the db.
|
|
* 6. Export a collection.
|
|
* 7. Drop the collection.
|
|
* 8. Import the collection.
|
|
* 9. Add data to the oplog.rs collection.
|
|
* 10. Ensure that the document doesn't exist yet.
|
|
* 11. Now play the mongooplog tool.
|
|
* 12. Make sure that the oplog was played
