The four basic steps of any black box test are 1. Identify your oracles (How do you tell if something is a bug?), 2. Identify your "surfaces" (What are the variables that could change during testing?), 3. Identify your risks (What are the highest priority functions? - that will change as your testing progresses), and 4. Make a plan.

For oracles, do you have other devices to compare to? Do you have a list of formal requirements or an informal statement of how it should work?

For surfaces, is there any interface specifications or limitations? How is the RS-232 configured? What are the expected limits on the ADC?

For risks, what is the most important function to evaluate for now? Again, this will change as you get deeper into the testing.

For the plan, don't get fancy. Just figure out a set of tests that will cover the surfaces you identified in a reasonable amount of time. You probably want to start with some fast, basic steps and then expand from there as things appear to be working. (Tests never "pass", they just haven't been explored enough. Make it break!)

Sometimes, the unit tests simply gets too hard without hardware-in-the-loop.

The best way, is to ensure the hardware is encapsulated by an API which does not expose the any of the STM32 HAL header files, so you can create a PC-based mock implementation of the hardware API and run your test of the CLIENT of the API on a PC.

But sometimes it can also be run on target.

In terms of the RTC, your driver probably calls the SysTickSysTick of the ARM Cmsis. That one is pretty trivial to mock.

Introduction to std::vector C++ is a powerful programming language widely used in software development. One of its most essential components is the Standard Template Library (STL), which includes the versatile std::vector. This dynamic array can grow and shrink in size, providing a flexible way to manage collections of data. What is std::vector? std::vector is a sequence container in C++ that allows dynamic resizing. Unlike arrays, which have a fixed size, vectors can expand or contract as needed. This flexibility makes std::vector a popular choice for storing collections of data. Key Features of std::vector

• • • Dynamic Size: Can grow or shrink as needed.
    • Contiguous Memory: Elements are stored in contiguous memory locations, enabling efficient access and cache performance.
    • Automatic Memory Management: Handles memory allocation and deallocation automatically.
    • Range Checking: Provides at() function for bounds-checked access.

How to Declare and Initialize a std::vector Here are some basic ways to declare and initialize a vector: #include <iostream> #include <vector>   int main() { std::vector<int> vec1; // Empty vector of integers std::vector<int> vec2(10); // Vector of 10 integers, initialized to 0 std::vector<int> vec3(10, 5); // Vector of 10 integers, initialized to 5 std::vector<int> vec4 = {1, 2, 3, 4, 5}; // Vector initialized with list of integers   return 0; } Basic Operations on std::vector Adding Elements Elements can be added to the end of the vector using the push_back method: vec1.push_back(1); // Adds 1 to the end of vec1 vec1.push_back(2); // Adds 2 to the end of vec1 Accessing Elements Elements in a vector can be accessed using the [] operator or the at method: int firstElement = vec4[0]; // Access first element (no bounds checking) int secondElement = vec4.at(1); // Access second element (with bounds checking) Removing Elements Elements can be removed from the end of the vector using the pop_back method: vec1.pop_back(); // Removes last element from vec1 Iterating Over Elements You can use a range-based for loop or an iterator to iterate over the elements of a vector: for (int value : vec4) { std::cout << value << " "; }   for (std::vector<int>::iterator it = vec4.begin(); it != vec4.end(); ++it) { std::cout << *it << " "; } Advanced Operations on std::vector Inserting Elements You can insert elements at a specific position using the insert method: std::vector<int> numbers = {1, 2, 3, 4, 5}; numbers.insert(numbers.begin() + 2, 10); // Insert 10 at the 3rd position Erasing Elements Elements can be removed from a specific position using the erase method: numbers.erase(numbers.begin() + 2); // Remove element at the 3rd position Resizing the Vector The resize method adjusts the size of the vector: numbers.resize(3); // Resize vector to contain only 3 elements numbers.resize(5, 100); // Resize vector to 5 elements, new elements initialized to 100 Clearing the Vector The clear method removes all elements from the vector: numbers.clear(); // Clear all elements Common Pitfalls and Best Practices Avoid Using [] for Out-of-Bounds Access Using the [] operator does not perform bounds checking, which can lead to undefined behavior. Use at for safer access: try { int value = numbers.at(10); // This will throw an exception if out of bounds } catch (const std::out_of_range& e) { std::cerr << "Out of range error: " << e.what() << std::endl; } Reserve Capacity for Efficiency If you know the approximate number of elements in advance, use reserve to allocate memory and avoid multiple reallocations: numbers.reserve(100); // Allocate memory for 100 elements Avoid Excessive Copies When passing a vector to a function, use references to avoid copying: void processVector(const std::vector<int>& vec) { // Processing vector without copying } Conclusion std::vector is a powerful and flexible container in C++ that allows you to manage dynamic collections of data efficiently. By understanding and utilizing the basic and advanced operations of std::vector, you can write more efficient and maintainable C++ programs. Whether you are managing a list of students, storing sensor data, or handling any dynamic array of elements, std::vector is an invaluable tool in your C++ toolkit. Summary of Key Points

• • • Dynamic Size: std::vector can grow and shrink as needed.
    • Memory Management: Automatically handles memory allocation and deallocation.
    • Safe Access: Use at for bounds-checked access.
    • Performance: Contiguous memory allocation improves performance.
    • Flexibility: Easily insert, erase, and resize elements.

By mastering std::vector, you will enhance your ability to handle dynamic data structures in C++, preparing you for more complex programming challenges. Happy coding!
