|
10 min Complete test suite per custom object |
40+ Test cases generated per object, automatically |
100% Execution path coverage guaranteed |
Zero Workshops needed for test case design |
|
EXECUTIVE SUMMARY Testing custom SAP objects is one of the most time-consuming, error-prone, and expertise-dependent activities in any S/4HANA transformation programme. A single ABAP program can require 3 to 5 days of manual effort to design, write, and review test cases — cases that are often incomplete, assumption-based, and inconsistently structured. The Test Case Generation AI Agent eliminates this entirely. In 10 minutes per object, it reads live ABAP execution logic directly from the system, constructs a complete test suite covering all functional, negative, edge case, authorization, and integration scenarios, and delivers a structured document with Pre-Conditions, numbered Test Steps, and precise Expected Results — without a single manual test case being written. |
|
The Hidden Scale of the Testing Bottleneck For a landscape of 500 custom objects, manual test case creation — averaging 3 to 5 consultant-days per object across design, writing, and review — consumes between 1,500 and 2,500 consultant-days before a single test is executed. This pre-testing investment is invisible in project plans, systematically underestimated in budgets, and consistently on the critical path of every SAP transformation programme. The Test Case Generation AI Agent converts this structural bottleneck into a 10-minute automated process. |

MANUAL TEST CASE CREATION Traditional Approach |
AI AGENT TEST CASE GENERATION Test Case Generation Intelligence |
|
3–5 days per object for test case design, writing, and review |
10 minutes — complete, structured test suite per object |
|
Test cases based on developer memory and outdated documentation |
Test cases derived from live ABAP execution logic — system truth |
|
Inconsistent format, depth, and coverage across authors |
Standardised Pre-Conditions / Test Steps / Expected Results — every time |
|
Edge cases and exception branches routinely missed |
100% execution path coverage — every branch, every condition, every option |
|
Negative test cases almost always absent from manual suites |
Functional, negative, edge case, authorization, and integration TCs all auto-generated |
|
Authorization scenarios never documented in test cases |
Authorization checks identified from AUTHORITY-CHECK statements — TCs written automatically |
|
Review cycles add 1–2 additional days per object |
Output is review-ready — numbered, structured, and immediately programme-usable |
|
Test assets not reused — recreated for every programme wave |
Versioned, structured output reusable across regression, UAT, and future upgrades |
|
Execution-Derived Intelligence Reads live ABAP code, selection screen logic, database table interactions, authorization checks, and all execution branches — no documentation or developer input required |
Complete Coverage Automatically Generates Functional, Negative, Edge Case, Authorization, Integration, and Regression test cases in a single automated pass — six dimensions, zero manual effort |
Review-Ready Structured Output Every test case includes Pre-Conditions, numbered Test Steps with exact T-codes and field names, and precise Expected Results — formatted for immediate QA team use |

|
01 |
System Connection & Object Scope Initialization Minutes 1–2 — Establish full object context before reading a single line of code ▸ Establishes secure, read-only connection to the SAP system containing the target custom object ▸ Identifies object type: PROG/P (Executable Program), Function Module, Class Method, BDC Program, or Interface Object ▸ Extracts object metadata: name, package, object type, created by, created date, last modified date — populating the Overview section automatically ▸ Loads the SAP Test Case Taxonomy: the complete framework covering all test types, priority classification rules, and coverage dimensions ▸ Initialises SAP module context: which business domain does this object serve? FI, MM, SD, PP, WM, HR, Basis, or Cross-Module? ▸ Sets coverage targets: minimum test cases per execution branch, mandatory coverage of all selection screen options and action modes |
|
02 |
Deep Code Reading & Execution Path Mapping Minutes 2–5 — Understanding every branch, condition, and business function the object performs ▸ Extracts complete ABAP source: main program body, all INCLUDE programs, subroutines, class definitions, and method implementations ▸ Parses all selection screen elements: radio button groups, checkboxes, input fields, range parameters, and screen-conditional logic ▸ Maps every execution branch: IF/ELSE conditions, CASE statements, LOOP constructs, nested logic, and exception handlers ▸ Identifies all database interactions: SELECT statements with join conditions, table keys (e.g. ZMM_STK_CONF_H, ZMM_STK_CONF_I, ZSD_DEL_POD), and data retrieval patterns ▸ Detects all posting operations: BAPI calls, standard function module invocations, goods movement posting, and document creation ▸ Extracts all authorization checks: AUTHORITY-CHECK statements, authorization objects (S_TCODE, M_MSEG_BWA, etc.), and conditional access patterns ▸ Identifies ALV grid configurations: column definitions, toolbar layout, sort/filter/export capabilities, and layout settings ▸ Surfaces application log usage: SLG1 log object names (e.g. ZMM_ERR), message classes, error/warning/success message patterns |
|
03 |
Business Function Semantic Analysis Minutes 5–7 — Translating code logic into human-readable business test scenarios ▸ Applies SAP-domain AI reasoning to translate each code block into a precise business function description ▸ Identifies the business scenario each selection screen option represents — as seen in ZMMRP_STOCK: R_1=Stock Confirmation (AO08), R_2=Stock Transfer (AO12), R_3=Delivery Confirmation (AO34), R_4=OBD Confirmation (AO22) ▸ Classifies each executable path by business criticality: High (core business function), Medium (supporting function), Low (edge scenario) ▸ Identifies dependencies between execution paths: which actions are prerequisites for others (data retrieval before posting) ▸ Maps the pre-condition landscape: which authorizations are required, which data must exist, which status codes must be in place ▸ Identifies the full expected outcome spectrum: success messages with document numbers, error messages with T-code references, status code updates, ALV column sets ▸ Detects data state change operations: which tables are written, which status fields are updated (e.g. ZDPW_INT_FILE status to 'C' or 'E') |
|
04 |
Test Case Generation Across All Coverage Dimensions Minutes 7–9 — Building the complete test suite from execution intelligence ▸ Functional Test Cases: one per identified execution path — every radio button option, every action mode, every message type, every posting scenario ▸ Negative Test Cases: invalid file numbers, missing authorizations, empty data sets, already-processed records, locked objects ▸ Edge Case Test Cases: boundary file number ranges, maximum selection criteria, empty result sets, duplicate processing attempts, concurrent access scenarios ▸ Authorization Test Cases: authorized user — programme opens, all options accessible; unauthorized user — authorization error message displayed, S_TCODE check referenced ▸ Integration Test Cases: ALV export to Excel, SLG1 application log display, MB03 material document verification, VL03N delivery document check, SE16 table status verification ▸ Regression Test Cases: full load batch processing (R_12), sequential multi-message-type processing, post-reset reprocessing flow ▸ Priority assignment: High for core document posting and data retrieval, Medium for supporting functions (log display, reset, mark as error/complete), Low for edge scenarios ▸ Systematic numbering: TC-FUNC-001 through TC-FUNC-NNN following the standardised naming convention |
|
05 |
Structured Document Assembly & Delivery Minutes 9–10 — The review-ready test case document, formatted for immediate programme use ▸ Assembles the complete document: Section 1 Overview with object information table, Section 2 Functional Test Cases with index table and complete detailed cases ▸ Formats every test case with the three-column structure: Pre-Conditions | Test Steps | Expected Results — matching the sample document format exactly ▸ Writes Pre-Conditions in precise, actionable language: SAP login requirements, table-level data prerequisites, authorization object requirements, status code dependencies ▸ Numbers Test Steps sequentially with bold action verbs, exact transaction codes, precise field names and labels, and explicit navigation paths ▸ Writes Expected Results as specific, verifiable, observable system responses — success messages with variable data, column names in ALV grids, status code values, document types created ▸ Generates the test case index table: S.No, Test Case Title, Priority classification — enabling risk-based test execution planning ▸ Outputs in the format specified: structured HTML or Word document, with AI-assisted content disclaimer and version control metadata |

|
Executable by Any Tester — Not Just SAP Experts Because the agent writes test steps using exact transaction codes, precise field names, specific radio button labels, and explicit keyboard shortcuts extracted directly from the program's selection screen, any tester — regardless of SAP experience level — can execute the test case precisely and verify the outcome without consulting an ABAP developer or functional consultant. This decouples test execution from consultant availability and dramatically increases testing throughput across the programme. |
|
What Manual Test Writing Produces |
What the AI Agent Generates |
|
Pre-condition: 'Have the right access to run the program' |
Pre-Conditions: Authorization for S_TCODE (ZMMRP_STOCK); data in ZMM_STK_CONF_H and ZMM_STK_CONF_I tables; at least one file with message type AO08; display rights for MM data |
|
Step 1: 'Open the transaction and pick the correct option' |
Step 1: Type ZMMRP_STOCK in SAP command field, press Enter. Step 2: Enter 100001 in File No field. Step 3: Select radio button R_1 (AO08 — Stock Confirmation) in Block B1. Step 4: Select R_7 (Display) in Block B2. Step 5: Press F8 |
|
Expected: 'Data shows on screen correctly' |
Expected: ALV grid displays with columns — File Number, Company Code, Line Number, ASN Number, Delivery Quantity, UoM, Storage Location, Batch Number. Status bar shows '25 records selected' |
|
No cross-system validation step |
Integration step: Navigate to SE16, enter ZMM_STK_CONF_H, verify records match ALV display. Confirm row count matches status bar message |
|
No negative test case for this scenario |
TC-FUNC-NEG: Enter invalid file number 999999. Execute. Expected: ALV grid empty, status bar shows 'No records found'. No error dump or system crash |
|
Priority not assigned — manual judgment applied ad-hoc |
Priority: High — identified as critical business process; inventory confirmation from external warehouse systems |
|
The Quality Difference Is Structural, Not Cosmetic The gap between AI-generated and manually-written test cases is not wording polish — it is a structural quality difference. AI-generated cases are grounded in what the system actually does: which tables are read, which fields appear in the ALV, which status codes are set, which documents are created, which T-codes verify downstream state. Manually-written cases are grounded in what the author remembers the system does. In testing, this distinction determines whether critical defects are caught before go-live — or discovered by the business after it. |

Reusable Test Asset Every wave, every release |
|
For QA Leads Complete test suite available before sprint begins — team focuses on execution, defect triage, and stakeholder sign-off rather than test writing |
For Programme Managers Test case creation removed from critical path — programme velocity increases and go-live readiness confidence improves measurably |
For Business Owners Every business scenario tested — including the edge cases, negative paths, and authorization scenarios that manual testing consistently leaves uncovered |
|
Compounding Returns Across Programme Waves In a transformation programme with multiple testing phases — Unit Testing, Integration Testing, System Integration Testing, User Acceptance Testing, and Regression — the AI-generated test suite serves as the master baseline for every wave. When an object is modified, the agent is re-run and produces a delta analysis highlighting new or changed execution paths requiring updated test cases. This eliminates the need to recreate or manually update test cases between waves — the single most invisible and underestimated testing effort in every SAP programme. |
|
What Scales Poorly with Manual Testing |
What the AI Agent Delivers at Scale |
|
Per-object effort does not decrease as landscape grows |
10 minutes per object — consistent at object 1 and object 1,000 |
|
Knowledge dependency: who knows which object best? |
Zero knowledge dependency — agent reads the system directly, every time |
|
Test quality degrades under time pressure and schedule compression |
Quality is constant — generated from code, not from memory or morale |
|
No baseline for regression — test cases recreated each wave |
Versioned assets serve as regression baseline across every subsequent wave |
|
Audit evidence for test coverage is anecdotal and incomplete |
Structured, complete test documentation for every object — audit-ready by default |
|
Custom code decisions made without test coverage insight |
Test asset implicitly inventories custom behaviours — informing Clean Core decisions |
|
The Test Case Generation AI Agent delivers a complete, structured test suite per object in 10 minutes. Execution-derived. Fully covered. Precisely written. Ready for immediate programme use. This is how SAP transformation programmes test faster, test better, and go live with genuine confidence. |
