2. An SAP R/3 System Component
CATT: What Is It?
An SAP R/3 System Component
Tools > ABAP Workbench > Test > Test Workbench > CATT
Little-known but Valuable Tool
Highly underutilized
Like AutoTester or Mercury Interactive
Automates repetitive work
Simple macro-like recording
Can execute remotely (RFC)
Improves system quality
Enhances human productivity

3. CATT: Uses Data Loading Testing Simulates keyboard entry of data
Master, Transaction, Configuration
Can read data variants from an external file
Populate refreshed “Sandbox” or “Training” Client
Testing
Unit test
Scenario test (“string” or “chain”)
Integration test
Volume test
Stress test
Modular and reusable

4. Testing is historically an IT weakness
CATT: Why Teach It?
Testing is important
importance of test quality, quantity, and scope
unit, scenario, integration, regression types etc.
Testing is historically an IT weakness
most common causes of ERP failures/pain
Ambiguous requirements, insufficient investment in Organizational Change Management, End User Training and Testing
typically reduced to meet budget / timeline
need to test more productively
get more done in less time

8. DO NOT use in Production Environment
CATT: Considerations
Prerequisites
R/3 navigation and transaction entry experience
programming / database knowledge helpful but not necessary
DO NOT use in Production Environment
will update the database
not subject to authorizations screening

13. Using the CATT Made Easy Guidebook
CATT: Exercise
Using the CATT Made Easy Guidebook
Validate that your User ID is authorized to use CATT (pages 4 – 6)
Record a CATT test case for transaction FK01 – Create Vendor (pages 7 – 12)
Save your new test case (pages 13 – 14)
Prepare test case to be used to load data by selecting fields to be used as import parameters (pages 15 – 19)
Export parameters to an external file in order to supply parameter variables (variants) (pages 20 – 24)
Run the test case to load data records (pages 25 – 28)
Add text Comments to your test case (page 29)
