Testing SAP R/3: A Manager's Step-by-Step Guide

Chapter 10. Planning and Construction of Test Cases

The construction and execution of test cases verify and validate the captured in-scope requirements or the request for new system changes. Test cases contain test conditions, test data, and expected results to verify the design, functionality, and development of SAP advanced business application programming (ABAP) objects, security settings, segregation of duties, work flow, data archiving, business warehouse (BW) reports, and service-level agreements (SLAs) for system performance. A combination of test cases forms a test scenario, whereas a test script is the sequence of actions that executes a test case.

Test cases can be designed in spreadsheets, text editors, or within test management tools. Project deliverables such as business process procedures (BPPs), flow process diagrams, and functional and technical specifications are excellent sources of information for designing test cases.

Templates and guidelines are hereby provided to build robust test cases.

Well-written test cases exhibit the following characteristics and attributes:

• Can be reused for user acceptance testing (UAT) with minimal or no modifications.

• Trace back to testable requirements or other existing documentation (BPPs, flow process diagrams, technical or functional specifications).

• Include preconditions. ...
