Why structured testing SAP® ?

SAP® systems:Are ‘always’ customized, Are often linked to other legacy systems and other software packages,Often require different local (customized) implementations,Often involve the migration of data between systems, Regularly need ‘changes’ due to legal requirements,Often require functional improvements,Regular upgrades and hot fixes after deployment are a ‘MUST’Often control the complete business process

Developer Testing

Developer Testing: Technical tests of low-level components (e.g. a conversion module)

8


Transaction Testing

Transaction Testing: Testing a single transaction (e.g. VA01 Create Sales Order). Transaction testing shall be conducted to confirm the operation of transactions + configuration checks (e.g. default values, mandatory fields etc.)


In-Stream Testing

In-Stream Testing: Testing of a flow within 1 single process. In-Stream Testing is testing chains of transactions that flow together and which reflect important business process and scenarios.

9


Cross-Stream Testing

Cross-Stream Testing: End-to-end testing of integrated processes through execution of predefined business flows (within SAP or collaboration between SAP and legacy systems).


Acceptance Testing

Acceptance Testing: In-Stream or Cross-Stream Tests by the user community with the objective of formal acceptance. In some cases, and for practical reasons, the Acceptance Tests are combined with Cross- or even In-Stream Tests.

Test Coordinator

! For a Test Coordinator, it is important to combine ‘in depth test knowledge’ with ‘high-level SAP®knowledge’ (has to know the core business flows of an organization)

Ability to set up a test process,Compose the overall planning,Define the high-level test requirements,Coordinate and follow up the testing activitiesCoordinate and follow up testers

Knowledge of Test Management ToolsKey-Role in the test process


Challenges Test Coordinator

Complexity: for E2E Acceptance Testing you need coordinate different user groups and you have to put them in a logical business chainMostly there is an external developer/integrator. Testing is not their core capability.Implementations can be on different locationsIntegration with other packages and legacy systemsDifferent processes within SAP® that need to be integrated.

Phase 1: Generic Test Planning

Determine scope of projectSAP® testing in maintenance projectDefine regression test approach

Determine high level test strategy-> Test strategy matrix per SAP ® module

List all SAP® transactions in logical business/testing flowInventory of (available) test scenarios and ancestor test scenariosInventory of relevant SAP® documentation: business flow, work instructions, business process proceduresGeneric priority analysis: SLA rating and usageAnalysis cross-module impactListing of tester profile per transaction



Test strategy matrix: content:One test strategy matrix per SAP® module Different worksheets per matrix

The test strategy matrixSLA rating of each transactionUsage of each transaction Transactions with roles: list of simple roles in SAP® against transactions per module -> for authorization testing

Only useful for the completion of the test strategy matrix
