To integrate GoogleTest with CMake, you configure your CMakeLists.txt to find the GoogleTest package, link the test executable against the gtest_main library, and register it with CTest using add_test to run tests during the build process.

Writing C++ unit tests with GoogleMock involves creating test fixtures using the TEST_F macro and defining mock classes with MOCK_METHOD to simulate interface behaviors, allowing you to verify interactions and isolate dependencies for robust integration testing.

Yes, you can enable code coverage and sanitizers in CTest by configuring your CMake build with specific compiler flags like -fsanitize=address for sanitizers and -coverage for coverage, ensuring quality assurance data is collected during test execution.

Test-driven development in C++ using GoogleTest requires writing failing tests before implementation, configuring CMake to build the test targets, and iterating on your code until all CTest assertions pass with sanitizers enabled to ensure robustness.

While CMake is not strictly required to run GoogleTest, it is the recommended approach for build system integration because it pairs natively with CTest to automate test execution, manage dependencies, and streamline the configuration of coverage and sanitizers.

GoogleTest failures are often caused by memory errors or undefined behavior. Compiling your C++ tests with address sanitizers enabled through CMake helps detect memory leaks and out-of-bounds access, providing precise diagnostics to resolve debugging issues.
