Waterfall
Older or traditional method of software development. Tests are run at the final stage of the development cycle, that is, on completion of coding. Due to the fact, that you do the test at the very end, you do not manage to detect special design or/and development issues early on, accordingly, this style is very challenging. The client has the chance of seeing the app for the first time only after its release has been approved by QA team.
Agile / Scrum / Lean
These methods of software development are hipper and newer. The tests are integrated during the coding. The client is involved in the process at an early stage actively running tests with every minor release.
Agile / Scrum
Sets of features are deployed and tested according to schedule. Features do not depend on each other, and if one feature has bugs, this should not affect other features.
Lean
Very alike to Agile and Scrum, all but development, release and testing of one feature are done at a time. This method allows isolating defects even further.
