Automation Vs Manual Testing?

automated testing is better because of its accuracy and to minimize human errors on the manual testingbut some times automated testing may need higher cost on establishing the technology.

As always, the question is wrong, as there is no automation testing. Every testing whether using the latest digital equipment's still require's human intervention, thus it will still be called "manual testing". Digital equipments still needs to be set, installed and programmed before it can perform its intended task. Unlike, analog equipments, results can be read and interpreted much more easier.

The question should have been, analog vs. digital testing. 

Automation gives mass production and similarity.

Manual gives more accuracy and add value of acknowledgement of the specialty.
