- Add `%WINDIR%\System32\WindowsPowerShell\v1.0\Modules` (Windows PowerShell $PSHOME) to the end of the default PSCore 6 module path (i.e. the module path as initially set at startup). - Cause an error to be thrown by `Import-Module` when a module with `CompatiblePSEditions` not containing `"Core"` is being loaded from the 'System32' module path. - Suppress output of modules listed by `Get-Module -ListAvailable` from Windows PowerShell $PSHOME when `CompatiblePSEditions` does not contain `"Core"`. - Introduce the `-SkipCompatibilityCheck` switch parameter on both `Import-Module` and `Get-Module` to respectively allow importing incompatible modules and listing incompatible modules. - Adds a `PSEdition` column to the `PSModuleInfo` table view format. - Ensures that completions are not given for incompatible modules on the System32 module path. |

Pester Testing Test Guide
Also see the Writing Pester Tests document.
Running Pester Tests
Go to the top level of the PowerShell repository and run: Start-PSPester
inside a self-hosted copy of PowerShell.
You can use Start-PSPester -Tests SomeTestSuite*
to limit the tests run.
Testing new powershell
processes
Any launch of a new powershell
process must include -noprofile
so that
modified user and system profiles do not causes tests to fail. You also must
take care to call the development copy of PowerShell, which is not the first
one on the path.
Example:
$powershell = Join-Path -Path $PsHome -ChildPath "pwsh"
& $powershell -noprofile -command "ExampleCommand" | Should Be "ExampleOutput"
Portability
Some tests simply must be tied to certain platforms. Use Pester's
-Skip
directive on an It
statement to do this. For instance to run
the test only on Windows:
It "Should do something on Windows" -Skip:($IsLinux -Or $IsMacOS) { ... }
Or only on Linux and OS X:
It "Should do something on Linux" -Skip:$IsWindows { ... }
Pending
When writing a test that should pass, but does not, please do not skip or delete
the test, but use It "Should Pass" -Pending
to mark the test as pending, and
file an issue on GitHub.
