waht is the diff b/w Environment variable and Global
variable in qtp?? explain types of variable in qtp??

Answer Posted / medabalimi

Environment Variables:
As the name implies the Environment variables contain the
information related test environment and machine
environment.
Two types 1.Built-In and 2.User Defined. Though the Built-
in values seems to be constant they are actually variables,
the machine takes care of maintaining appropriate values.
Not editable directly by a user from QTP. Ofcourse the user
defined can be modified any time from QTP.
They are just Name & Value pairs and are of type string
data. Accessible globally in QTP tests. Example:
UserID="SomeName" Where Name="UserID" and Value="someName"

We can say the Environment variables are subset of Global
variables in one aspect. That means we can declare
variables with Name Value pairs of any type supported by
the script language. We have the advantage of defining
dimentional/hierachical data (multi dimentional arrays)
which is not possible with environment variables.
