Int4 APITester

Int4 APITester helps create, organize and execute tests of end-to-end business flows in SAP and non-SAP environments.

Principle of operation

Int4 APITester utilizes available API's in SAP and in integration platforms to inject, inspect, fetch and compare business messages to provide integration testing, supported with service virtualization.

There are three main pillars to the test execution and virtualization:

1. Virtualization of external systems
   Int4 APITester can inject messages pretending to be an external system in the integration process. Also, it can capture messages submitted in the direction of external systems and validate them for content and structural correctness.

2. Middleware platforms' behavior inspection
   Int4 APITester utilizes existing APIs of tested integration platforms to access message history/trace and inject messages into the platform. By capturing historical documents, injecting new messages, and analyzing how they were processed, Int4 APITester can technically and functionally validate the integration platform behavior by comparing current execution to historical data.

3. Validation of business documents and operation with SAP backend
   Many tests can be done on the integration platform itself. However, validation of business documents requires accessing the backend system involved in the process. The main feature available in Int4 APITester is the ability to validate business documents by comparing values stored in the database. Additionally, Int4 APITester can work with fetching and injecting IDocs, Proxies and re-trigger outputs from SAP documents.

   1. Database validation is enabled by additional function modules that system administrators can install either separately or as part of the Int4 Suite Add-on on the tested systems.

   2. In case the database validation is not an option, API calls specific to the tested system may be used (if available) to validate business document data.
