🔧 Test Bench

Project Overview

This program is used to demonstrate how to combine a small mathematical library with a data‑driven testing engine and a timestamped logging subsystem

Core Objectives

1. Showcase clean modular C design Separate translation units (math_library.c, test_harness.c, logger.c, main.c) keep pure logic, test orchestration, logging, and UI strictly isolated.

2. Provide a reusable micro‑testing scaffold Tests are declared as plain‑C structs holding a description, a function pointer to the math operation, input operands, and an expected value. Extending coverage is as simple as adding one line to the testCases[] array.

3. Illustrate lightweight file‑based logging The logger writes [YYYY‑MM‑DD HH:MM:SS] [LEVEL] message to either program.log (runtime events) or test.log (per‑run test results). Log routing is swapped on the fly from the menu to avoid stream conflicts.

Interactive Workflow

Menu Option	Purpose	Behind the Scenes
1 · Run Individual Test	Execute one selected case	Clears test.log → switches logger → runs chosen test → restores program.log.
2 · Run All Test Cases	Execute the full suite	Same log rotation, iterates through testCases[].
3 · View Log Files	Inspect program.log or test.log in‑app	Opens chosen file read‑only and streams to stdout.
4 · Exit	Graceful shutdown	Flushes & closes the active log, frees input buffers.

🛠️ Build & Run

Windows User:

1. Download VS Code and C/C++ Extension in VS Code.
2. Download MinGW. Link: https://sourceforge.net/projects/mingw/
3. In Terminal, type gcc main.c logger.c math_library.c test_harness.c -o test-bench.exe for compile the program and build the executable.
4. In Terminal, type .\test-bench.exe to run the program.

Mac User:

1. Open Terminal, type xcode-select --install to install the Command Line Tools.
2. In Terminal, type gcc main.c logger.c math_library.c test_harness.c -o test-bench for compile the prgram and build the executable.
3. Lastly, type ./test-bench to run the program.
