Few days ago I posted about a tiny module I wrote to skip the entry point function in a script. I got few reactions telling me that there are better ways to organize your scripts, and they were all correct. Putting your code into a module and distributing it that way, or splitting the script into different files and combining them during build are both better than having a single file with everything.

Testing a self-contained script file with Pester is difficult. I visited this idea few times before, for example here and never reached a solution that I would like, but every time I am getting closer and closer.
