Pester VS PowerShell

Pester is what's used for most Powershell testing. While it has some pretty amazing features, it does have issues with .NET class method mocking and sometimes scope can be weird. Here's a simple example:

This is the fun that is Powershell mocking, or at least the form that someone completely new to Powershell would write. One thing I must say is that Pester's mocking capabilities are quite easy to work with. It reminded me of pytest mock patching, only well, simpler. Most of the time spent fighting tests was due to the nuances of pipeline flow. For example, you can see that your mocked method was called X many times through something like this:

The folder blocked all users from reading the files so if you open up the files it looks empty, even tho you have show hidden files turned on. You can't delete it since it says that you need access from TrustedInstaller. This is cleaver by the hacker since trusted installer is actually the name of a windows feature. HOW-EVER by using the command line I found out that the folder contains framework like these two. https://github.com/d1pakda5/PowerShell-for-Pentesters https://github.com/pester/Pester

I'm really surprised that nobody in this thread has mentioned Pester. PowerShell has its own automated unit testing framework that is incredibly versatile. You do need to know PowerShell in order to really make it shine, but if there are some simple tests that your class requires such as "make sure this value conforms to this regex value", Pester is pretty easy to pick up and utilize.

Once you start building code/scripts that are used consistently, consider adding Pester testing to your work. Most sysadmin managers may not get it, but if you're talking to dev managers, they'll absolutely get the importance of unit testing and why it's a good tool to have. Again, down the road. Learn the basics first.

Finally, the Pester testing framework, which ships with Powershell, is a great way to ensure your code actually does what it's meant to do.

This smells like when PowerShell aliased curl and wget to a completely different command, with incompatible arguments.

PowerShell is available on macOS and Linux as well (source on Github: https://github.com/PowerShell/PowerShell). It may not be as well-integrated with things like system services management, but the language still works well. You can still use all the command line tools you're used to on Linux, of course.

nushell does look interesting, though the lack of a .deb repository does put it pretty low on my to-do list.

Issue #7940 discusses potential improvements to array slicing.

Note: This can be problematic as it prevents upstream commands from running their end {} block. See here. The new clean {} block introduced in PowerShell v7.3 does not suffer from this issue.

Can you give an example of something that PS can do that is built-in for text processing, instead of a proprietary symbolic query language?

https://github.com/PowerShell/PowerShell/blob/master/LICENSE... is the MIT license. (Microsoft supplies debs directly which may reduce the motivation for Debian to do so.)

Oh, heh, also https://github.com/PowerShell/PowerShell/blob/master/docs/bu... the build script is written in PowerShell, so there's a bootstrapping problem :-) (Debian has solved those before of course, but with community sentiment like the above maybe noone is motivated to bother.)

According to https://github.com/PowerShell/PowerShell/issues/19628, the default behaviour is invoked whenever the completion script returns no output. To attempt to do so, I tried exiting the script via returning an empty string, or using the return keyword to exit the script completely, unfortunately with no avail. Is there a technique to achieve what I want, and is there any documentation about it other than the official one? Thank you in advance.
