HP Business Process Testing
Automated testing can be used in an environment with
multiple SAP Applications, Ex. R/3, SAP SA, SAP FI, EBP, BW, etc. It also
covers the usages and requirements which are critical to deploy an Automated
Testing solution. This article will help Consultants alike gain insight in the
application of Automated Testing in an SAP Environment and help to bring the
best return on investment.
Quick Test Professional for Business Process Testing:
Business Process Testing is a role-based testing
model. It enables Automation Engineers and Subject Matter Experts to work
together to test an application's business processes during the application's
development life cycle.
Automation Engineers are experts in automated
testing. They use Quick Test to define the resources and settings needed to
create components, which are the building blocks of business process tests.
Subject Matter Experts understand the various parts
of the application being tested, as well as the business processes that need to
be tested, however they may not necessarily have the programming knowledge
needed to create automated tests. They use the Business Components and Test
Plan modules in Quality

Understand Business Process Testing
Business Process Testing is
a role-based testing model that enables Subject Matter Experts—who understand
the various parts of the application being tested—to create business process
tests in Quality Center Quality

Business Process Testing
uses a keyword-driven methodology for testing, based on the creation and
implementation of business components and business process tests. A business
component is an easily-maintained, reusable unit comprising one or more steps
that perform a specific task within an application. A business process test
comprises a series of business components, which together test a specific
scenario or business process. For example, for a Web-based application, a
business process test might contain five components—one for logging on to the
application, another for navigating to specific pages, a third for entering
data and selecting options in each of these pages, a fourth for submitting a
form, and a fifth component for logging off of the application. Business
components and business process tests are generally created in Quality Center
Components in QTP
QuickTest enables you to
create and modify two types of components: business
components and scripted components. A business
component is an easily-maintained, reusable unit comprising one or more steps
that perform a specific task. A scripted component is an automated component
that can contain programming logic. Scripted components share functionality
with both test actions and business components.
Automation
Engineer:
The Automation Engineer is
an expert in using an automated testing tool, such as QuickTest Professional.
The Automation Engineer works with the Subject Matter Expert to identify the
resources that are needed for the various business process tests.
The Automation Engineer then
prepares the resources and settings required for testing the features
associated with each specific component, and stores them in an application area
within the same Quality
Center
Each application area serves
as a single entity in which to store all of the resources and settings required
for a component, providing a single point of maintenance for all elements
associated with the testing of a specific part of an application. Application
areas generally include one or more shared object repositories, a list of
keywords that are available for use with a component, function libraries
containing automated functions (operations), recovery scenarios for failed
steps, and other resources and settings that are needed for a component to run
correctly. Components are linked to the resources and settings in the
application area. Therefore, when changes are made in the application area, all
associated components are automatically updated.
The
Automation Engineer uses Quick Test features and functionality to create these
resources from within Quick Test. For example, in Quick Test, the Automation
Engineer can create and populate various object repositories with test objects
that represent the different objects in the application being tested, even
before the application is fully developed. The Automation Engineer can then add
repository parameters, and so forth, as needed. The Automation Engineer can
manage the various object repositories using the Object Repository Manager, and
merge repositories using the Object Repository Merge Tool. Automation Engineers
can also use Quick Test to create and debug function libraries containing
functions that use programming logic to encapsulate the steps needed
HP Business Process Testing Terminology:
Application
Area:
A collection of resources
and settings that are used for the creation and implementation of business
components. These include function libraries, shared object repositories,
keywords, testing preferences, and other testing resources, such as recovery
scenarios. An application area provides a single point of maintenance for all
elements associated with the testing of a specific part of your application.
You can define separate application areas for each part of your application and
then associate your components with the appropriate application areas.
An easily-maintained,
reusable unit comprising one or more steps that perform a specific task.
Business components may require input values from an external source or from
other components, and they can return output values to other components.
A
non-automated business component created in Quality Center
An automated component that
can contain programming logic and can be edited in QuickTest using the Keyword
View, the Expert View, and other QuickTest tools and options
A spreadsheet-like view that
enables tests and components to be created, viewed, and debugged using a
keyword-driven, modular, table format.
A document containing VBScript functions,
subroutines, modules, and so forth. These functions can be used as operations
(keywords) in components. You can create and debug function library documents
using the QuickTest function library editor.
Business
Process Test:
A scenario comprising a
serial flow of business components, designed to test a specific business
process of an application.
Component
Input Parameters:
Variable values that a
business component can receive and use as the values for specific,
parameterized steps in the component.
Component
Output Parameters:
Values that a business
component can return. These values can be viewed in the business process test results
and can also be used as input for a component that is used later in the test.
Variable values defined
within a component. These values can be received and used by a later parameterized
step in the same component
Values that an operation or
a component step can return for use within the same component. These values can
be viewed in the business process test results and can also be used as input
for a later step in the component.
The various types of users
who are involved in Business Process Testing
Automation
Engineer:
An expert in QuickTest
Professional automated testing. The Automation Engineer defines and manages the
resources that are needed to create and work with business components. The
Automation Engineer creates application areas that specify all of the resources
and settings needed to enable Subject Matter Experts to create business
components and business process tests in Quality Center
Subject Matter
Expert:
A person who has specific
knowledge of the application logic, a high-level understanding of the entire
system, and a detailed understanding of the individual elements and tasks that
are fundamental to the application being tested. The Subject Matter Expert uses
