Running Pester Tests inside Visual Studio

Question

After installing PowerShell Tools for Visual Studio 2015 I created a new Powershell Module Project which creates a MyProject.psd1 a MyProject.psm1 and a MyProject.tests.ps1 file.

MyProject.tests.ps1 file looks like this

Describe "Connect-Database" {
    Context "When Connection To Database" {
        $result = Connect-Database -host localhost -user admin -pass pass
        It "Should Return True" {
            $result | Should Be $True
        }
    }
}

Connect-Database is a function from MyProject.psm1 and is exported via MyProject.psd1

# Functions to export from this module
FunctionsToExport = 'Connect-Database'

Running a powershell console and executing

Import-Module .\MyProject.psd1
Invoke-Pester

works great and returns

Describing Connect-Database
   Context When Connection To Database
    [+] Should Return True 627ms
Tests completed in 627ms
Passed: 1 Failed: 0 Skipped: 0 Pending: 0

Here comes my problem: PowerShell Tools come with a test adapter and my test shows in Test Explorer.

But If I execute it, it always fails with The term Connect-Database is not recognized as cmdlet function script file or operable program

Even adding Import-Module .\MyProject.psd1 to the MyProject.tests.ps1 file does not help. Any ideas how to load my module prior to running the tests?

Answer 1

I added Get-Location | Write-Host to MyProject.tests.ps1 file and figured out that the working directory was C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE

I didn't check that in the first place because I believed the test adapter would just execute Invoke-Pester in the working directory

Eventually I solved this with

Split-Path $PSCommandPath | Set-Location
Import-Module (".\" + (Split-Path -Leaf $PSCommandPath).Replace(".tests.ps1", ".psd1"))
