How to load the PowerShell script that was in different directory while executin

I am having my .ps1 saved in directory1 and mt .tests.ps1 in directory2 with in the same folder.
Folder view
In general we use to write the script as follows when the test file and script file are in the same folder

$here = Split-Path -Parent $MyInvocation.MyCommand.Path
$sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path) -replace '\.Tests\.', '.'
. "$here\$sut"

But I am having them in different folder, so how can I load the path so that the script file should get loaded

Example of a solution for your question:

$here = Split-Path -Parent $MyInvocation.MyCommand.Path
$sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path).Replace('.Tests.ps1','.ps1')
. "$(Join-Path -Path $here -ChildPath "..\Pester\$sut" -Resolve)"

Getting the following error

Join-Path : Cannot find path ‘D:\PowerShell\Pester\TestPester\Pester\PowerShellTest1.tests.ps1’ because it does not exist.
At D:\PowerShell\Pester\TestPester\MyProject.Tests\PowerShellTest1.tests.ps1:3 char:6

I’m sure you can find out yourself. The code is not really complex. Most likely the folder layout is different from what you’ve posted earlier or you’ve removed the … in my example.

Good luck.

I have written as per you posted, My .ps1 is in A folder and my test script in B folder, I believe the code you have given is searching in current directory B instead of A

I have achieved as follows

$project = (Split-Path -Parent $MyInvocation.MyCommand.Path).Replace(".Tests", "")
$sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path).Replace(".tests.", ".")
. "$project\$sut"
