Int4 Shield Lite

Int4 Shield Lite is designed to assist in creating, organizing, and executing tests for selected integration platforms. It facilitates SAP CPI test-driven development and accelerates SAP PI/PO to CPI migration scenario through test automation.

Int4 Shield Lite offers a subset of the Int4 APITester features, focusing on virtualization and and the middleware testing. The Int4 APITester manual applies to Int4 Shield Lite, with the exception of supporter platforms, backend validation and external API features, which are detailed in the manual.

Principle of Operation

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

Open

There are two main pillars to test execution and virtualization:

1. Virtualization of External Systems
   Int4 Shield Lite can simulate external systems by injecting messages into the integration process. Additionally, it can capture messages directed to external systems and validate them for content and structural correctness.

2. Middleware Platforms' Behavior Inspection
   Int4 Shield Lite 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 By capturing historical documents, injecting new messages, and analyzing how they were processed, Int4 Shield Lite can technically and functionally validate integration platform behavior by comparing current execution to historical data.
