I want to test how my tools generated files and folders in the destination with different arguments passed to the program. However, in my old code, I put all the logic of working with arguments in the static int main( string[] args) function. I could not use Interface and Dependency injection to mock the CLI tools because CommandLineUtils does not have an interface library. Luckily, I found this guidance from the owner of CommandLineUtils, and he advised that "Split the command-line argument parser and application execution into separate class structures" to test various options programmatically. It is a great suggestion, and I rewrote my program by adding class CommandLineOptions and adding logic to class Generator to make it works with CommandLineOptions. I can kill two birds with one stone by this change: code refactoring and writing better tests. Another problem I had was my folder structure. Before, I put the project's sln file, .git file , and src files in the root of the folder. However, when I added a new test project for Shinny-SSG, I had it outside my git folder, and it would be impossible to commit the change and put it in my remote repository. To resolve this, I had to change my folder structure to this:
The testing framework that I chose is XUnit. The first reason is that it is trendy compared to another test framework such as NUnits. I created test methods stub from the existing code by Create Unit Tests command. To use it with Xunit, I have to implement the XUnit.net.TestGenerator extension to my project.
