About the mannual testing

Manual Testing is nothing but testing the functionality of 
an application manually with out using automation testing 
tools means by writing a test cases chek manually

Manual Testing : It is the process of Identifying Bugs in a 
Given application by manually, with out using any 
Automation Testing  Tools
(loadrunner,QTP,Silktest,Winrunner......) By writing Test 
Cases.

Testing a application using all the testing methodolgys
i.e., using test cases, test scenarios and other methods
without using any tool such as ( Winrunner: Used for Windows
application, QTP: Used for Web applications, Load Runner:
Used for Performance testing ). where we use the these tools
to generate the Scripts which can be reused to test the
application. where as for Manually testing the application
we test the application by giving certain inputs and we see
whehter we are getting the expected results or not.

Manual testing : It is the process of intention to find the
defects manually and questioning a program in order to
evaluate it...with respect to the customer Requirements
(Tester can only find the defects where as developer fixes
that defect called as Bug...If a customer face the problem
in an application he called it as fault/failure)

Manual Testing is the oldest and most rigorous type of 
software testing . Manual testing testers to perform manual 
test operation on the test software without help of test.

Manual testing is laborious activity that requires the 
tester to posses a certain set of qualities: to be patient, 
obseravant, craetive, openmided and skillfull.

Maual testing helps discover and record any software bugs 
or descrepancies related to the functionality of the 
product.

A test engineer conducts a test on application build without
using a tool is called manual testing

Manual Testing is process in which all the phases of STLC
(Software Testing Life Cycle) like Test Planning,Test 
Development,Test Execution,Result Anaysis, Bug Tracking and 
Reporting are accomplish successful manually with the human 
efferts.
In Manual Testing we will test the application with valid 
and invalid inputs and expecting the results about 
application.
In Manual Testing we are not using any Automated Tools(like 
Win Runner,QTP etc).We will apply all types of testing 
manually on the application to get proper output
