Travis Plunk 1523c218a6 Make sure that SettingFile arg is parsed before we load the settings (#7449)
Make sure that SettingFile arg is parsed before we load the settings

- Add ability to parse some setting before console host is created
- Trigger the Parse before the console host is created
- disable snapin loading from loading setting before this point
- re-enable mac logging tests.

Also, fix the following Travis-ci issues:

- make sure the Linux and macOS caches are separate to reduce the size
- update the macOS image to the closest image as used by the official build system (equivalent to VSTS hosted mac builds)

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.
