Variable empty within It but given in Context

Pester
1

Hi *,

I have a Pester test with Test-ModuleManifest throwing an error now (worked before).
Very strange: it seems that it is an issue also connected to AppVeyor as it works locally.

The issue:

Context "Integrated Manifest Test" {
        Write-Host "ModuleManifestPath: $ModuleManifestPath"
        It 'Passes Test-ModuleManifest' {
            $null = Test-ModuleManifest -Path $ModuleManifestPath -ErrorAction Stop -WarningAction SilentlyContinue | Should -Not -Throw
        }
}

This throws an error about -Path cant be bound as it is null.

Funny: my debugging output just outside of It is working fine and returning the right Path to my Manifest which is defined on top of all tests.

Any ideas?

Thanks,
M.

Where is the $ModuleManifestPath defined ? did you change pester version and what is the pester version you use ?

Hi @kvprasoon

it is latest Pester on all systems (5.0.2 as I remember).

On AppVeyor and Azure Pipeline it is not working (both), locally (Win10) it is working.

I define the vars directly on top of my Test-Script, before first describe:

$moduleName = $env:BHProjectName
$ModuleManifestPath = "$($pwd)\$($moduleName).psd1"

The problematic test can be seen in my original post, within Context, before It the var has the content I want. Within It it seems to be empty.

Best,
M.

Solved it: since v5 you have to put all in some BeforeAll{} context, otherwise it may not work.

Thanks for letting us know the cause.
