C++ Unit Testing: Mocking Dependencies with GMock

Writing robust C++ applications requires effective unit testing, but complex dependencies often make isolation difficult. This course solves that challenge by teaching you how to use GMock to replace real components with simple, controlled mock objects. By the end of this program, you will master the techniques required to decouple dependencies and ensure every unit of your C++ code is tested thoroughly, predictably, and reliably, significantly improving overall code quality and maintainability. What you'll learn: * Understand the core principles of effective unit testing, test isolation, and dependency management in C++. * Configure and utilize the fundamental components of the GTest framework, including assertions and test fixtures. * Master the syntax and patterns for defining and controlling mock objects using the GMock framework. * Apply techniques for stubbing function calls and verifying specific object interactions and behaviors. * Practice designing testable C++ classes by applying core dependency injection concepts. * Learn to write parameterized tests to efficiently cover multiple data scenarios with minimal code. The course begins with foundational concepts, covering GTest setup and basic assertions, before progressing into advanced GMock usage for creating complex mock objects and setting up expected behaviors. This entirely text-based training is designed for programmers new to formal testing practices or those transitioning to C++ unit testing. No prior experience with GMock or GTest is required.
