PSClassUtils

Summary

PsClassUtils, is a Powershell module which contains tools to ease the work with Powershell Classes.

One cool feature is available is the fact that it can generate UML-like Class Diagrams in png format of your scripts / modules in a glimps! (See Write-CUClassDiagram)

Since version 2.6.0 we have also added the possibility to automatically generate your pester tests for your entiere module / script / file(s).( See Write-CUPesterTest below.)

Write-CUClassDiagram

Allows to generate UML diagrams of powerShell scripts / modules that contain PowerShell classes.

Prerequisites

This module has a dependency on Kevin Marquette's PSGraph powershell module. The prerequisites can be installed either manually, or by using the following methodology:

Import-Module PSClassutils
Install-CUDiagramPreRequisites

Functionality

Drawings

Write-CUClassDiagram currently allows to draw diagrams (or components of diagrams) of the follow items:

• Document a Class
  • it's Properties
  • it's Methods
  • it's Constructors
  • it's Inheritance

Has a relationships (Composition) is currently not supported. (But is planned for a future release)

Inputs

It is possible to draw diagrams from classes in the following different manners:

• On a folder level
  • This will create a diagram and document each independant .ps1 file that contains a class. If no classes are found, it will be an empty square.
• File base (.ps1)
  • you can point the function to a single .ps1 file, and will generate the diagram for all the classes located in that file.
• File base (.psm1)
  • you can point the function to a single .psm1 file, and will generate the diagram for all the classes located in that file.

Examples

A script called inheritance.ps1 contains the following code:

Class Woop {
    [String]$String
    [int]$number

    Woop([String]$String,[int]$Number){

    }

    [String]DoSomething(){
        return $this.String
    }
}

Class Wap :Woop {
    [String]$prop3

    DoChildthing(){}

}

Class Wep : Woop {
    [String]$prop4

    DoOtherChildThing(){

    }
}

Calling Write-CUClassDiagram

Write-CUClassDiagram -Path ".\Inheritance.ps1"

Results

Live examples from existing modules on the internet:

I took the 'liberty' to run Write-CUClassDiagram on some well known modules available on the internet that are classed based. These are all great modules, and I recommend you have a look at them!

PSClassUtils

This is the result of running Write-CUClassDiagram on this module itself

Class.HostsManagement

Below is the export of the Class Diagram of a module I wrote that helps to manage HostsFiles accross the network using PowerShell classes. (The project is accessible Here)

Poshbot

Write-CUClassDiagram allows to generate diagrams of complex class based modules, and gives you the ability to have a global picture of any project quickly, without reading through the code. PoshBot is probably the best example:

Write-CUPesterTest

Since version 2.6.0 the PsClassUtils module received a few new cmdlets related to pester tests. The most interesting one is without a doubt the: Write-CUPesterTest

As it's name implies, this function allows to automatically generate your pester tests. (Click on the image below for an example.)

Community contributions

for 'HacktOberFest' I created an issue to push people to use the module on their classes, and PR us their classes + examples.

AclApp

Thanks to LxLeChat !!

Acl class is used to create a 3 levels folder structure in a standardized way. The acl creates both folders and corresponding groups and set acl.
