• Embedded Software Unit Testing with Ceedling (Apr. 14, 2020)
  Unit testing is a technique of breaking the code in small units of the entire code. These units can be verified to check the behaviour of a specific aspect of the software. One of the major challenges involved in unit testing of embedded software is that the code interacts with the hardware peripherals. In mostcases, hardware cannot be accessed during unit tests. Keeping hardware interaction as thin as possible helps in testing most of the code by dividing it into small pieces. These pieces can then be independently tested without hardware interaction.
