Using gMock in C++ projects
In the world of software testing, particularly within the methodology of TDD, a mock object plays a crucial role. It’s designed to mimic the behavior of real objects by implementing the same interface, allowing it to stand in for the actual object in tests. However, the power of a mock object lies in its flexibility; developers can specify its behavior at runtime, including which methods are called, their call order, frequency, argument specifications, and the return values. This level of control turns mock objects into powerful tools for testing interactions and integrations within the code.
Mocks address several challenges in testing complex or interconnected systems. When developing prototypes or tests, relying solely on real objects might not be feasible or practical due to constraints such as external dependencies, execution time, or costs associated with real operations. In such cases, mocks provide a lightweight, controllable substitute...
