What is the issue?

Hi!

This is a specific pester 4.9.0 issue. I know it is not supported anymore, but if you guys could just give me a hint at what I should look at in order to fix that would be really great!

I do have a class that contains a method that does the following:

Class PesterTestHelper {
    [object]$TestData
    [String[]]$Path
    [String]$Version = "Latest"

    TestHelper(){}

    [void] InvokeTests([String[]]$Path) {
        #Accepts eithern a string or an array of strings that should be the path to the test script(s) or the folder containing test scripts.
        if([string]::IsNullOrEmpty($Path)){
            throw "No path provided for tests"
        }

        if($this.Version -eq 'Latest'){
            Import-Module -Name Pester -Force
        }else{
            Import-Module -Name Pester -RequiredVersion $this.Version -Force
        }

        $this.Path = $Path
        $this.TestData = Invoke-Pester -Path $Path -PassThru -Show None
    }
#...
}

This class is than invoked from a function with the following lines.


    $TestHelper = [PesterTestHelper]::New()
    $TestHelper.SetVersion("4.9.0")
    $TestHelper.InvokeTests("C:\MyTests\")

(When invoked from the function, or directly instanciated in a script file, I do have the same error message).

With Pester 5 it works just as expected, but with Pester 4.9.0 I get the following error message.

Pester\SafeGetCommand: C:\Program Files\WindowsPowerShell\Modules\Pester\4.9.0\Functions\PesterState.ps1:74:49

     | The term 'Pester\SafeGetCommand' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name,

Enter-CoverageAnalysis: The property 'CommandCoverage' cannot be found on this object. Verify that the property exists and can be set.

Am I missing some prerequisites ? Should I do my call to pester in another way ?

Thanks a lot for your guidance!
