Can manual testing be replaced by automation

Question

Can manual testing be replaced by automation?

Answer 1

Automation is the combination of testing tools into the test environment in such a manner that the logging, test execution, and evaluation of results are done with slight human interference. A testing tool is a software application and helps to automate the testing procedure. But this tool is not the absolute answer for automation. One of the big mistakes made in testing automation is automating the incorrect things during development, everything cannot be automated. The best components to automate are repetitive or tedious tasks. Therefore some companies initially start with manual testing and then see which tests are the repetitive or tedious and then only those are automated.

We should not try to automate:

a) Code and document review should not be automated it will only cause difficulty.

b) If the software is under development and going through many changes should not be automated because automation testing will not be useful.

c) The test scripts should not be automated that will run once in a while.
