Why do Test Automation - Manual Testing take too Long !

This is one of the main reason for automating our test suites and becomes more important for ongoing projects with more funcitonalities each day.  Most of the application have various functionalities integrated so well that test scenarios increase exponentially. Although it's pity that sometimes higher management doesn't understand this fact. Non-Tester only understand this challenge when they see some bug after release, which is worst part. Let me control my emotions here :), as we are not discussing that part of test-teams here.

If we consider as example of Agile Software Development, after firt realease there can be an expectation to release shorter versions, dot releases or minor fixes in short duration of time OR even every day. And in this kind of situation it is close to impossible to test everything and certify. Many times Automation laso takes too much time for such projects, but that is something which can handled using Vm enviornments to run various test scenarios in parallel.

Regression is one of the area which is more challenging and difficult to handle manually. When an application is manually certified and we do some changes in code, it becomes difficult to cover everything again manually and we may miss some important bug due to this. For regression, automation gives at least some level of confidence apart from manual testing done my the team.
