Unit Testing with C Training in Dhaka, Bangladesh

Unit testing with C training focuses on equipping participants with the skills to write and execute unit tests for C applications using testing frameworks like CUnit or Unity. The course covers the fundamentals of setting up testing environments, writing test cases, and validating functionality through assertions. Participants learn how to isolate individual components of their C code and test them independently, ensuring correctness at the unit level. Hands-on exercises focus on identifying edge cases, debugging failing tests, and using mocking techniques to simulate dependencies. By the end of the training, attendees gain the expertise to implement effective unit testing strategies in C, improving software quality and maintainability.
