poshspec

Run poshspec Infrastructure tests in Pester in a Windows container.

You may know Serverspec? I started with it on Linux and used it also on Windows, but using Ruby, bundler, Gemfile and so on in a Windows container seems like a little overhead.

Let's enter poshspec and easily write your Windows infrastructure tests. See the Wiki for more details and introduction. It is a package in the PowerShell Gallery.

Create a infratest.ps1 file:

#Requires -Module Poshspec

Describe 'Services' {
    Service Dnscache Status { Should Be Running }
    Service bits Status { Should Not Exist }
}

Describe 'Files' {
    File C:\License.txt { Should Exist }
    File C:\inetpub\wwwroot\iisstart.htm { Should Contain 'text-align:center' }
}

Describe 'Registry' {
    Registry HKLM:\SOFTWARE\Microsoft\Rpc\ClientProtocols { Should Exist }
    Registry HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ "SyncDomainWithMembership" { Should Be 1  }
    Registry 'HKLM:\SOFTWARE\Callahan Auto\' { Should Not Exist }
}

Describe 'Http' {
    TcpPort localhost 80 PingSucceeded { Should Be $true }
    TcpPort localhost 80 TcpTestSucceeded { Should Be $true }
    Http http://localhost StatusCode { Should Be 200 }
    Http http://localhost RawContent { Should Match 'X-Powered-By: ASP.NET' }
    Http http://localhost RawContent { Should Not Match 'X-Powered-By: Cobal' }
}

Then build the image with

docker build -t poshspec .

And run your tests with

docker run -v "$(pwd):C:/code" -w C:/code poshspec powershell -File infratest.ps1

Here is an example from my Mac with a windows-docker-machine running:

$ docker run -v C:$(pwd)/spec:C:/spec -w C:/spec poshspec powershell -file container.ps1
