Testing interactions between software modules or components.

Integration testing ensures that different modules or components of a software system work together correctly. It validates data flow, API interactions, and system integrations, catching issues that arise when combining individual units, ensuring cohesive functionality.

• Validates interactions between components.
• Ensures seamless data flow and integrations.
• Catches issues missed in unit testing.
• Supports modular and microservices architectures.
• Improves overall system reliability.
