Bruce Payette dfb3866c5d Support backgrounding pipelines with ampersand (#3360)
Implements support for backgrounding pipelines with &. Putting & at the end of a pipeline will cause the pipeline
to be run as a PowerShell job. When a pipeline is backgrounded a job object is returned. Once the pipeline is
running as a job, all of the normal job cmdlets can be used to manage the job. Variables (ignoring process-specific
variables) used in the pipeline are automatically copied to the job so
    copy $foo $bar &
just works. The job is also run in the current directory instead of the user's home directory as is the case with Start-Job.Implement

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 "powershell"
    & $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 $IsOSX) { ... }

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.
