MANUAL TESTING:
1.manual testing is less expensive then automation testing
2.manual testing didnot require any special kdg like as 
automation.
3.Adhoc ,monkey,gui testings cannot be done with automation 
testing
4.sometimes some errors are being left by the automation 
which could be caught by the manualtest
5.Any object which is not recognise by the automated tool 
such object testing is also done by manual testing.

AUTOMATION TESTING;
 1.Automation testing is fast compared to manual when we 
are doing testing on large projects.
2.Automation testing is Reliable as it is free from human 
errors.
3.Automation testing is repeatable as we can perform same 
kind of tests.
4.Using automation testing we can reuse script for future 
projects or other modules.
5.Using automation testing we can progrem which help us to 
get hidden information.

a tester conductes any test on applicatoin build without 
using any testing tool is called manualtesting


a tester conductes any test on application build with the 
help of testing tool is called automation testing

Manual Testing/Black box testing:- Is a testing, where
tester uses the application in order to test it.( testing
for properties, appearance and functionality).

Automated testing:- Tester creates test scripts that test
the application similar to manual testing( testing for
properties, appearance and functionality).
Automated testing is good for regression testing, as same
scripts can be run again and again.

Manual testing are done by human resources
needs large investment
time consuming and tedicious process

automation testing done by automated tools
fast,
comprehensive
resualble
reliable
eliminates human errors

manual testing:
tester->test the application ->if ER=AR the product is 
released -> if ER !=AR then it is given to the developer 
for rectifying the defects and then given to the tester 
after rectification
Automation testing:
tester->tool-> appl->ER=AR the product is released else if 
ER!=AR it is given to the developer for rectification of 
defects after he rectifify the defects it is given to the 
tester
TOOL-> tool is manmade software which works on tester 
instructions

The main difference between manual and automation testing 
is in manual testing we can not record the results,but in 
automation testing we can record the results and use it for 
future.
But intila testing of any build will be Manula testing only.
