PSUseConsistentWhitespace - False validation in switch statements

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

1. Create script with following contents:

$TargetLogSize = 64
switch ($TargetLogSize) {
    { $_ -le 64 } { 64 }
    { $_ -ge 64 -and $_ -lt 256 } { 256 }
    { $_ -ge 256 -and $_ -lt 1024 } { 512 }
    { $_ -ge 1024 -and $_ -lt 4096 } { 1024 }
    { $_ -ge 4096 -and $_ -lt 8192 } { 2048 }
    { $_ -ge 8192 -and $_ -lt 16384 } { 4096 }
    { $_ -ge 16384 } { 8192 }
}

1. Execute following settings:

$settings = @{
    IncludeRules = @(
        'PSUseConsistentWhitespace',
    )
    Rules        = @{
        PSUseConsistentWhitespace  = @{
            Enable          = $true
            CheckInnerBrace = $true
            CheckOpenBrace  = $true
            CheckOpenParen  = $true
            CheckOperator   = $false
            CheckPipe       = $true
            CheckSeparator  = $true
        }
    }
}
Invoke-ScriptAnalyzer -Path C:\temp\test.script.ps1 -Severity Warning -Settings $settings

Expected behavior

No warnings to be returned

Actual behavior

Receive warnings on space before an open brace.

Commencez par reproduire l’exemple d’instruction switch avec la règle PSUseConsistentWhitespace et les paramètres fournis. Suivez ensuite la validation des espaces blancs de cette règle pour les clauses switch, puis vérifiez que les fausses alertes signalées n’apparaissent plus, tandis que les véritables alertes d’espacement restent détectables.
