Parameterization
Basics
What is a parameter?
A parameter is a variable used to
denote or represent data in our tests.
Why do we parameterize?
We do parameterization when we want
multiple sets of data to be used for the same set of operations.
Suppose we want to automate an
application for Localization Testing. We can use the same code and
parameterize the input data for the application steps and import the
different data for different language from different data table or
excel file for each language.
In another example, we can use
parameterization for input values for an application with same set
of test data as input data. When we have one application as Web and
another as Windows with same business flows.
What do we parameterize?
We use parameterization for the below
reasons -:
- Checkpoints
- Object Properties for a selected step.
- Object Properties in the Object Repository.
- Operation arguments for a selected step.
What are the different types of
Parameterization available in UFT?
The different types of
parameterization available in UFT are -:
- Test and Action Parameterization.
- Data Table Parameterization.
- Environment Variable Parameterization.
- Random Number Parameterization.
What are the different types of
Test Parameterization?
The different types of Test
Parameterization are -:
- Input Parameterization
- Output Parameterization
Both the parameterization
information can be added from the related Test Properties Pane.
In the Properties Pane –
Parameterization tab we have options to -:
a) Add – Input/Output Parameter
b) Edit – edit information related
to added parameters such as Name, Value and Type of parameter.
c) Delete – delete a parameter.
We can use these parameter values to
pass to the actions present in the test and also to other tests in
the same Solution.
What is Action Parameterization?
The different types of Action
Parameterization are -:
1. Input Parameterization
2. Output Parameterization
Both the parameterization
information can be added from the related Action Properties Pane.
In the Properties Pane –
Parameterization tab we have options to -:
a) Add – Input/Output Parameter
b) Edit – edit information related
to added parameters such as Name, Value and Type of parameter.
- Delete – delete a parameter.
What are the different types of
Parameterization through Environment Variables?
The different types of Environment
Variables are -:
- User-Defined Internal Environment Variables
- User-Defined External Environment Variables
- In-Built Environment Variables.
User-Defined Internal Environment
Variables
In the case of User-Defined Internal
Environment Variables we can set up variables from the FILE
Menu-Settings option-Environment tab.
We can add the environment variables
by giving the name and value of the variable from the above pane.
We can also export the User-Defined
Environment variable to an XML file from the menu.
User-Definned External Environment
Variables
In the case of User-Defined External
Environment variable we can create an external XML file in the
format accepted by UFT and import the created XML file to UFT with
the options present in the menu. The XML file format should start as
-:
<Environment>
<Variable>
<Name>VariableName1<\Name>
<Value>VariableValue1<\Value>
<Description>Variable
Description1<\Description>
<\Variable>
<Variable>
<Name>VariableName1<\Name>
<Value>VariableValue1<\Value>
<Description>Variable
Description1<\Description>
<\Variable>
<\Environment>
UFT In-Built Environment Variables
There are multiple built-in
environment variables in UFT which consist of information related
to the test. These are variables such as OS Name and Test Name. We
can use these environment variables in our code to check with an IF
structure and run the required code.
What is the Data Driver?
Data Driver in UFT is used to quickly
parameterize several or all occurrences of a property of a test
object, checkpoint property and method argument when they have multiple occurrences of a constant in the action.
Data Driver functions like Find and
Replace All in excel.
