getQuery(): It is used to instantiate the Database.QueryLocator object. This is useful when testing the start method and the start method automatically locks the set of records in the batch.

QueryLocator object when you are using a simple query (SELECT) to generate the scope of objects used in the batch job. If you use a querylocator object, the governor limit for the total number of records retrieved by SOQL queries is bypassed but we can retrieve up to 10,000 records.
