Integration Testing
IntegrationDefinition
Integration Testing is a phase in the software development lifecycle where individual software modules are combined and tested as a group to ensure that they function together correctly.
Detailed Description
Integration Testing is crucial in the ERP ecosystem because it validates that different modules or systems, which are developed either independently or incrementally, can work in harmony with each other. Typically, it occurs after unit testing and before system testing. The focus is on interface and data flow between modules, ensuring the overall system functions as expected when various segments are interconnected.
Key Features
- Detection of inconsistencies in business logic
- Evaluation of system performance when modules interact
- Identification of interface errors
- Validation of data transfer and communication between modules
Common Modules
Financial Accounting
Ensures financial data accurately reflects transactions from other modules like procurement and payroll.
Sales and Distribution
Tests the integration between sales order processing and other modules like inventory and finance.
