Over the course of the product development life cycle, unit testing saves time and money, and helps developers write better code, more efficiently.

When should I write unit tests?

For Test-Driven Development (TDD), you write unit tests before writing any implementation. This makes your implementation details in your code shorter and easier to understand. In this instance, the best time to write unit tests is immediately. For others, most developers write unit tests after the code’s been written.

Why is app.config not consulted when unit testing?

The app.config of your console application will not be consulted when you’re running the unit tests. While you can define the app settings in another config file for your unit test project, unit testing to interfaces using dependency injection may help break down the areas that your unit tests will be covering into more manageable portions.
