Quick Test Professional - The starters Guide

Environment variables in QTP are same as to global variables which can be accessed through any part of the code. These variables can prove to be useful when we want a variable to be shared across many reusable tasks and functions.

  Environment variable types are:

1. Built in variables
2. User Defined variables:

• Internal
• External 

Built in variable:

are designated as read-only, which represent the information about the test on which the test is run, such as Test path and Operating system.

Syntax: Variable = Environment ("variable name")

The Environment Variable names can be accessed by:

Go to "File" select "Test Settings" select "Environment" Tab.

Internal User defined variable:

This variables are saved with the test and are accessible within the test only.

To save the "User Defined Variables", Select "User Defined" in the Environment Tab Window and click on "+" icon; enter the Name and Value as shown below

External User defined variable:

This can be created using a list of variable-value pairs in an external file format as .xml.

It can be loaded into the test as shown:

Environment variables: Methods and Properties:

• ExternalFileName Property
• LoadFromFile Method
• Value Property

ExternalFileName:

This is used to get the name of the loaded external environment variable file mentioned in the Environment pane of the Test Settings dialog box. 

If there is no external environment variable file is loaded, then it returns an empty string.

Syntax:  Environment.ExternalFileName

x= Environment.ExternalFileName 

print x

LoadFromFile:

This is used to loads environment variable file which is specified.

The environment variable file must be an XML file.

Syntax: Environment.LoadFromFile (Path)

Value Property:

This is used to retrieves the environment variables value.

We can also set the value only for user-defined environment variables.

Syntax:

 To setting the value of a user-defined environment variable:

Environment.Value(VariableName) = NewValue
