software testing manual code example

Example 1: what is manual testing

Literally, it means testing an application with your hands. 
It is performed by humans, no tools or codes are used.

Example 2: when manual testing

-Unstable test cases
-Tests that you will only run only once.
-The only exception to this rule is that
if you want to execute a test with a very large 
set of data, even if it’s only once,
then it makes sense to automate it.
-Unfinished functionality
-Visual test cases
-Also Tests that need to be run ASAP
which usually a new feature which is
developed requires a quick feedback
so testing it manually at first making sense.
