Int4 Shield

Int4 Shield designed to assist in creating, organizing, and executing tests for selected integration platforms. It facilitates and accelerates test-driven development, regression testing and migration scenarios trough test automation.

Int4 Shield offers a subset of the Int4 APITester features, with a focus on virtualization and and middleware testing. The Int4 APITester manual applies to Int4 Shield, except for backend validation and external API features, which are detailed in the manual.

Principle of Operation

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

Open

There are two main pillars to test execution and virtualization:

1. Virtualization of External Systems
   Int4 Shield 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 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 By capturing historical documents, injecting new messages, and analyzing how they were processed, Int4 Shield can technically and functionally validate integration platform behavior by comparing current execution to historical data.
