Software Integration TestingAssembly Lines

Combine multiple software units into software components to perform integration testing that focuses on how the components interact with each other from a

control and data flow perspective using VectorCAST/C++.

Software integration testing vs Unit testingSoftware Integration Testing

Software integration testing Software unit testing

Test a software component Test a software unit, smallest testable section of source code

Test cases’ complexity varies Test cases have low complexity

Finding source code bugs may require tracing through the code Finding source code bugs are found quickly

Software components use the intended functionality Software unit may enter impossible cases

Communication errors can be detected Communication errors cannot be tested

Conformance of architectural design Architectural design cannot be tested

Both can use the same testing methodologies

Typical definitions: “An individual software component is a software package, a web service, a web resource, or a

module that encapsulates a set of related functions (or data).”

“Software component is a piece of code that carries out an application or part of an application.”
