A PowerShell based testing framework that helps you test your nuget packages.

Testing your nuget packages can be difficult especially if you're trying to write tests to be run on build server where Visual Studio might not be installed and if
you have my custom things built into your packages you'll need those things to be tested with iron-clad rules in a repeatable way. Running and verifying your nuget package in Visual Studio is not practical for you as a developer nor is it practical if you are trying to get to a hands-free deployment.

The goal of this framework is to make testing your nuget packages easy by giving you the strengths of PowerShell and the elegance of convention and testing semantics provided by Pester.

This project also aims to provide the developer with a way to run the tests as part of CI / CD gates on servers where Visual Studio is not installed. This helps with assuring that what your Continuous Delivery server is pushing out the door is what you expect it to be pushing out the door.

Basic usage

NOTE: The PackageManagement.Cmdlets.dll that is used to execute your nuget package against the fixture apps requires that you run a x86 PowerShell console in order for you to be able to load the module. The module is loaded via Setup.ps1 and can be commented out if you do not intend on executing your nuget package against a temp fixture application as a test.

1 Clone the project into your package directory (where your .nuspec file and package files are). If for whatever reason you want to keep the nuget-test project as a "git" repo then simple remove "remove-item nuget-test/.git -Recurse -Force" from the command below.

git clone https://github.com/nickfloyd/nuget-test.git; remove-item nuget-test/.git -Recurse -Force

2 Run Setup.ps1 in the root of the nuget-test directory in an x86 instance of PowerShell.

PS> .\setup.ps1

3 Write tests and place them in the nuget-test/test directory using the Pester syntax. ex.

Context "When package exists" {
	It "checks to see if content\my.config exists" {
		(Test-Path $PackageRoot\content\my.config) | Should Be $true
	}
	
	It "checks to see if content\my.dll exists" {
		(Test-Path $PackageRoot\content\my.dll) | Should Be $true
	}
	
	It "checks to see if content\my.dll is set to version 1.0.0" {
		[System.Diagnostics.FileVersionInfo]::GetVersionInfo("$PackageRoot\content\my.dll").FileVersion | Should be "1.0.0"
	}
}

4 Run the tests.

PS> Invoke-Pester

Support Libraries

These libraries are instrumental in getting this "framework" to actually work. Special thanks to:

  • Pester - a powerful testing framework for PowerShell
  • SharpDevelop's package management module - an amazing module that allows the developer to perform nuget commands outside of a Visual Studio instance
  • PowerSploit PETools - modules that help developers verify and peer into managed and unmanaged code.
  • Nuget - Package management for for Visual Studio

Requirements

Known Limitations

  • Currently if you want to run a package simulation using the PackageManagement Cmdlets you must be running in an x86 PowerShell console.
  • It seems that the PackageManagement Cmdlets will only load Visual Studio projects / solutions version 2010 or lower, though there might be a new build that should be used that might allow 2012 projects / solutions to be used.
  • Some $DTE functions do not always run as expected or will break when executed through the tests - more work needs to be done with this framework and $DTE to get better compatibility.
