SAP Test Acceleration and Optimization (SAP TAO)

SAP Test Acceleration and Optimization (SAP TAO):

Purpose Of SAPTAO:

The highly secure and mission-critical nature of enterprise resource planning (ERP) data requires many SAP customers to test their ERP applications and business processes regularly. Many SAP customers use expensive customized manual procedures to test processes and applications. Manual testing is time-consuming, and frequently requires a team of experienced quality assurance (QA) professionals. Subject matter experts also often need to spend a lot of time communicating the process data flow to testers. 
SAP Test Acceleration and Optimization streamlines the creation and maintenance of ERP business process testing. 

SAP Test Acceleration and Optimization helps QA specialists to break down a test into components which are:

Assembled into test cases in a simple interface, using drag and drop 
Parameterized for flexible reuse, such as reusing a test that has updated data 
Maintained easily and inexpensively, even when screens, flows, or service packs change 

SAP Test Acceleration and Optimization is designed for SAP-GUI-based applications. SAP Test Acceleration and Optimization users should be experienced quality managers who are familiar with the SAP Quality Center application by HP, SAP GUI ERP applications, and business process testing.

Automatic testing with SAP Test Acceleration and Optimization maximizes: 

Testing deployment 
SAP Test Acceleration and Optimization, with SAP Quality Center, dramatically reduces the amount of time required to build and execute test scripts. 

Reuse 
SAP Test Acceleration and Optimization eliminates the need to create new tests whenever a component changes. If one component in a group of tests changes, replace that component, and re-consolidate the tests

Maintenance 
SAP Test Acceleration and Optimization records component parameters. It provides a Microsoft Excel spreadsheet to save parameters for reuse and maintenance. SAP Test Acceleration and Optimization helps you to determine the need for repairs, and helps you to repair your components.

Robustness 
The SAP Test Acceleration and Optimization inspection process ensures that SAP Test Acceleration and Optimization tests are more robust during changes. Inspection examines the parameter in a component, not just the screen object behavior.
SAP TAO

The SAP Test Acceleration and Optimization Clent application runs on Windows System. It Performs 6 Key functions 
1 .PFA (Process Flow Analyzer)
2. Inspection/UI Scanner
3. Import/Export
4. Change Analysis
5. Repository
6. Consolidator

Configuration

License Validation:
* Once Installation is complete, Double Click on the SAPTAO Icon on the Desktop. SAPTAO UI Appears. 
* Click on the "Configuration" Link on the top right of the screen and select the "License" Tab
* Select the Solution Manager system from the System List 
* Click on Test SAP Connection (The text box on the right SAP TAO License with Text Enabled turns Green
Connection Settings:

* Click on the Connect Module on the Left hand Side Panel of SAPTAO UI.
* Select the SAP Managed system from the list and provide valid credentials
* Click on "Test SAP Connection" Button and then Click on "Save" Button
* The ICON displaying the selected current Backend system turns Green
* Provide Valid QC Connection details along with Domain and project details and click on "Save" Button
* The ICON displaying the connection state of QC turns Green
Configuration Settings

Click on the Configuration Link and set the following in the respective tabs as described below.

Inspection /UI Scanner

The Inspection tab page in the SAP Test Acceleration and Optimization client selects multiple SAP GUI screens and transactions for testing, in an easy-to-use interface. It then determines whether these screens are valid, and sends them to SAP Quality Center as screen components. 

Set up Inspection

Upload components to SAP Quality Center:

To upload the screen components to SAP Quality Center If this option is not selected, the parameters Overwrite components and Delimiter for Component/Unique Identifier on the Import/Export tab page are used to name new components

Component path

The location of components created during inspection 
Duplicate components are overwritten without confirmation. 

UI Scanner: 
A plug-in module for HP Quickest Professional enables you to collect information from one screen at a time, and sends the screen objects to HP Quality Center as a component. The UI Scanner scans all objects in the screen including dynamically generated objects. The UI scanner requires an active Quick Test Professional installation on your local work station.

Import/export 
Import/export exchanges components between the SAP Test Acceleration and Optimization client and SAP Quality Center. The import/export module does the following. 

Export components from the inspector in the SAP Test Acceleration and Optimization client to SAP Quality Center 
Import components from SAP Quality Center to the SAP Test Acceleration and Optimization client 
Export components from the local memory to SAP Quality Center 
Export a component from the UI scanner and send it to SAP Quality Center, in the background 

PFA also uses import/export while creating the test components

Procedure 
1. Choose Import/Export tab page. 
2. Select the required options. 

Process flow analyzer:
The process flow analyzer (PFA) records all user interactions, and the sequence of screens, in a business process, and stores them in the SAP Test Acceleration and Optimization repository. It automates inspection, retrieval of dynamic SAP GUI properties at runtime, and creation of components. 

Procedure 
On the PFA tab page, make the following settings: 
The PFA will create a second spreadsheet to store the recorded outputs
Do Not Use Screen Components 
Whether screen components are to be inserted in the test. If selected, only default components will be used. Do not select this option unless required. 

Steps for Process Flow analysis are:- 
1. To add a transaction, choose. 
2. Select a transaction e.g. VA01. Name for analysis is already populated with time stamp concatenated to it. You may change it. 
3. Choose "Start" for Process Flow Analysis.
Execute the process flow as a business user. 
6. After executing the transaction completely, stop the PFA by clicking on "Stop the PFA" button in the PFA controller window. 
7. A report is generated which captures the activities performed by business user 

Change analysis:
Change analysis analyzes the impact of changes due to upgrades, SAP patches, or custom development, on a test, component, or consolidated component. The impact is found by comparing the results of the technical bill of materials (TBOM), transport requests and SAP patches.

Set Folder for BPCA 
In this section, you specify: 
The folder created in SAP Quality Center to store the test set created by BPCA 
Whether to use BPCA result ID as the test set name 
Change analyzer functionality helps in repairing tests, which are impacted by a software change. SAP Test Acceleration and Optimization relies on SAP Solution Manager – Business Process Change Analyzer (BPCA) result. The BPCA result Id could be searched on the basis of a solution or project

Steps for Change Analysis:- 
1. Input your result Id, and choose "Change Impact Analysis". 

Repository 
The SAP Test Acceleration and Optimization repository is part of the SAP Solution Manager system, and stores data required to create, optimize and maintain components and tests. The repository contains the following:
User interactions and the sequence of screens in a business process 
Information specific to SAP Test Acceleration and Optimization, that cannot be retrieved by other tools 
Results or states during process flow analysis, before the component is created 

The SAP Test Acceleration and Optimization repository tools comprise the following. 

Component Explorer 
The user can see the list of all the components created by himself for a specified QC Domain and QC Project.

PFA Explorer 
The user can search for PFAs created till now, depending on search strings. The user can specify property to search on. The different properties which are possible to be searched on are:- 
• User 
• Analysis Name 
• Transaction 
• System 
• Client 
• Date Time 
• Language 

Once the search is done the user can click on one of the PFA to see more technical details.

Consolidation
Consolidation creates a single component from the objects and data in an SAP Quality Center test. The component contains all the code and screen elements in a test. It executes much faster than the individual components and helps you to maintain business processes. Consolidation also takes dependent tests into account.
