HLD is high level design. It gives only the layout of the
modules of the complete application and how it is expected
by the customers. Does not normally have enuf details for a
developers to start with the development. Prepared by the TM
or the Manager.
Where as LLD is Low level design. It gives the complete and
detailed requirement of all the modules etc. normally
prepared by project manager or the project lead.
A tester mainly works with the LLD.
