System Integration Testing (SIT)- A Detailed Overview
System Integration Testing (SIT) is a crucial phase in the software development lifecycle (SDLC) where individual software modules or components are combined and tested as a group to ensure that they interact and function correctly together as a complete system. Here's a detailed overview of System Integration Testing: Purpose: Verify Interactions : SIT verifies that various components of the system interact with each other as expected. Detect Interface Defects : It identifies defects related to interfaces between components. Validate Data Flow : SIT validates the flow of data between different modules or subsystems. Evaluate System Behavior : It evaluates the behavior of the integrated system against the specified requirements. Ensure Compatibility : SIT ensures compatibility between different hardware and software components. Key Components: Test Environment : A dedicated environment is set up to mimic the production environment as closely as possible. Test Cases : Test cases are
