5.4.0-rc1

In this release there are many fixes and improvements thanks @fflaten to providing most of them!

ANSI colors for output

Output is now printed with colors in AzureDevOps:

To achieve that, Pester detects if the host supports ANSI codes and uses them to output the string. You can control this by this new option:

[PesterConfiguration]::Default.Output.RenderMode

Default Description                                                                                 Value
------- -----------                                                                                 -----
Auto    The mode used to render console output, options are Auto, Ansi, ConsoleColor and Plaintext. Auto

And optionally switch back to classical ConsoleColor, or a new PlainText mode that outputs just text without any embedded formatting.

Check Multiple aliases for Should -HaveParameter

Should -HaveParameter can now ensure that there are multiple aliases set for a parameter.

function f { 
    param( [Alias('UserName')] $Name ) 

    $Name     
}


Get-Command f | Should -HaveParameter Name -Alias 'n', 'UserName'

InvalidResult:
Line |
   1 | Get-Command f | Should -HaveParameter Name -Alias 'n', 'UserName'
     | Expected command f to have a parameter Name, with aliases 'n' and 'UserName', 
     | but it didn't have an alias 'n'.

• Add support for multiple aliases (-Alias) to Should -HaveParameter by @dtewinkel in #2247

Always return to the original path

Pester captures the current path in which Invoke-Pester is invoked, and returns to this path after the execution of the test, even if the tests change it:

PS C:\projects\myModule> Invoke-Pester -Container (
    New-PesterContainer -ScriptBlock {
        Describe "d" {
            It "i" {
                Set-Location C:\Windows
            } 
        } 
    })

This will return back to C:\projects\myModule after your tests finish running.

• Always return to original CWD after running Pester by @fflaten in #2189
