Over View Of Manual Testing

    Manual testing is the process of manually testing Software Application for finding defects. Here Manual Test Engineers will play the role of an end user, and use most of all features of the application to ensure correct behaviour. To ensure completeness of testing, the tester often follows a written test plan that leads them through a set of important test cases.

This type includes the testing of the Software manually i.e. without using any automated tool or any script. In this type the tester takes over the role of an end user and test the Software to identify any un-expected behaviour or bug. There are different stages for manual testing like unit testing, Integration testing, System testing and User Acceptance testing.

Testers use test plan, test cases or test scenarios to test the Software to ensure the completeness of testing. Manual testing also includes exploratory testing as testers explore the software to identify errors in it.

After completing some part of the code   the testing is started the designed test cases or test scenarios will be executed & any differences between actual & expected results are reported as defects. Once the reported defects are fixed, the testers will retest the defect to make sure that the defects are fixed. The main goal of Software testing is to make software defect free & deliver good quality Product to customer.

Operators in VB Script

1) Arithmetic operators:

Operator	Description	Example
+	Addition - Add values on either side of the operator.                        If  a=10 and B=20 then	a + b will give 30
_	Subtraction - Subtracts right hand operand from    left hand operand               If  a=10 and B=20 then	a - b will give -10
*	Multiplication - Multiplies values on either side of Operator                          If  a=10 and B=20 then	a * b will give 200
/	Division - Divides left hand operand by right hand  operand               If  a=10 and B=20 then	b/a=2
%	Modulus - Divides left hand operand by right hand  operand and returns remainder	b % a will give 0

2) Comparison Operators:

=	Checks if the values of two operands are equal or not, if yes then condition becomes true. If  a=10 and B=20 then	(A=B) is not true
!=	Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.	(A! =B) is true.
<>	Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.	(A<>B) is true
>	Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.	(A > B) is not true.
<	Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.	(A < B) is true.
>=	Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.	(A >= B) is not true.
<=	Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.	(A <= B) is true.
!<	Checks if the value of left operand is not less than the value of right operand, if yes then condition becomes true.	(A! < B) is false.
!>	Checks if the value of left operand is not greater than the value of right operand, if yes then condition becomes true.	(A! > B) is true.
