4-2: Unit TestingSouthern New Hampshire UniversityCS 405: Secure Coding 09:11:55 GMT -05:00To begin with changes to the starter code, I included the gtest/gtest.h header file. In the main function, I included the InitGoogleTest amd returned RUN_ALL_TESTS().The InitGoogleTest function initializes the Google Test framework, parsing command-line arguments (argc and argv) to extract relevant information for test execution. This function call is crucial for setting up the testing environment before running any test cases. Following the initialization, RUN_ALL_TESTS() is called to execute all registered test cases. This function orchestrates the entire testing process, running each test case and providing a summary of the results. The return value of RUN_ALL_TESTS() is then used as the exit code for the program, allowing externaltools or scripts to interpret the outcome of the tests.CanAddToEmptyVector has been added to verify the ability to add a single value to an initially empty collection. This test ensures that the collection is no longer empty after the addition, and the size is correctly updated to reflect the insertion of a new element. These 09:11:55 GMT -05:00changes contribute to a more thorough evaluation of the class's basic functionality.CanAddFiveValuesToVector test case has been executed to validate the ability to
