Invoke-pester When Powershell file test is in a Function seems to not locate any tests

[rcoughtrey]

I have been reading and reading but just cannot pin point an answer to my issue or lack of knowledge.

Issue Outline:
When calling my tests with pester everything runs but no tests are ever found. I have dug around to find out that If the *.test.ps1 file being called is inside a powershell Function nothing is found. The moment I remove the function everything works as expected.

Here is a cut back version of my test sample:

Calling the invoke-pester

$Container = New-PesterContainer -Path "C:\QE\Pester\PesterStart.Test.ps1"

$Configuration = New-PesterConfiguration
$Configuration.Run.Container = $Container
$Configuration.TestResult.Enabled= $true
$Configuration.TestResult.OutputFormat = "NUnitXML"
$Configuration.TestResult.OutputPath = "Test-Pester.XML"
$Configuration.Output.Verbosity = "Detailed"

Invoke-Pester -Configuration $Configuration

===========
PesterStart.Test.ps1 file:

function Set-location
{
    [CmdletBinding()]
    Param
    (
        [Parameter(Mandatory=$False)][String]$NewCodes        
    )

BeforeAll{
Import-Module "C:\QE\Pester\Location.ps1" -Force
}

Describe 'Get urlLocation' {
    Context 'urlLocation Creation' {
        It "Auction Was set to east" {
            Set-location -Location "east" | Should -Be "east"
        }
    }
}
}

This will run but I get the following:
Starting discovery in 1 files. Discovery found 0 tests in 62ms. Running tests. Tests completed in 60ms Tests Passed: 0, Failed: 0, Skipped: 0 NotRun: 0

Now if I change PesterStart.Test.ps1 file to:

BeforeAll {
Import-Module "C:\Users\266542\OneDrive - CarMax\QE\Pester\Location.ps1" -Force
}

Describe 'Get urlLocation' {
    Context 'urlLocation Creation' {
        It "Auction Was set to east" {
            Set-location -Location "east" | Should -Be "east"
        }
    }
}

My output is

Starting discovery in 1 files.
Discovery found 1 tests in 131ms.
Running tests.

Running tests from 'C:\Users\266542\OneDrive - CarMax\QE\Pester\PesterStart.Test.ps1'

 Context urlLocation Creation
   [+] Auction Was set to east 5ms (2ms|3ms)

Any ideas :)

I have worked around my issue, I just remove the function from the first script that contained the tests. Just had make some changes in azure to support how that script/function was being called.

It still would be good to know why invoke-pester cannot call a script which has its tests in a function

You never called the function inside the pesterstart.tests.ps1 file.

Either way, having trouble understanding why you'd want this at all.

[rcoughtrey]

Calling the functions pesterstart.tests.ps1 to start the tests does not have issue. Its just that the script that is passed into invoke-pester cannot have a powershell function. I removed the function and just used params to get the data into the test script

Pester runs the file to find the tests, your file only defines a function, it never calls it, so Describe never runs and discovery finds nothing.

A test file can have functions in it, you just need the Describe blocks to run when the file is invoked. Either move them out of the function, or call the function at the end of the file.
