Hyunwoo Choiforhyunwoochoi.hashnode.net·Aug 14, 2022TDD ExampleBefore starting TDD, we need software spec and test cases. Our goal is demonstrating software development process with a simple example:fizzbuzz problem. Here is software spec for fizzbuzz problem: if given number is divided up by 3, print fizz. ...Discuss·34 readsTDD - Embedded System using Ctest driven development
Hyunwoo Choiforhyunwoochoi.hashnode.net·Aug 12, 2022Ceedling with Visual Studio CodeTest Driven Development is required to go through multiple times of small changes in production code and test code concurrently. It would be nice to have GUI IDE to load all files in one workspace. Also, you might want to debug test code during run-t...Discuss·59 readsTDD - Embedded System using Cceedling

Hyunwoo Choiforhyunwoochoi.hashnode.net·Aug 10, 2022How to deal with dependency issues among modulesIn general, firmware cannot be discussed without hardware dependency in embedded system. For example, led_controller module needs to use functions from interface_gpio module to control hardware. When we need to unit test this type of interface, the m...Discuss·34 readsTDD - Embedded System using Cceedling
