Because there is nothing special about Tasty it's a normal dotnet console program by default.

1. Run with dotnet watch

Given that you can simply use the build in dotnet watch to execute tests in watch mode.

dotnet watch run

There is some code inside Tasty that will detect if it's run from watch mode, and will clear the screen before each run, so the UX is a little bit better.

In the future there will be a separate CLI that allows you to control watch mode on a more granular scope, such as selecting which tests to run, etc.

2. Congratulations

You wrote your very first delicious watched tests! Next you will learn how to integrate into CI/CD with exit-codes.
