Research direction

Start with the supplied Invoke-Formatter reproduction and the two proposed Pester test contexts for Docker commands embedded in PowerShell. Trace how formatting handles the comma in the Docker --secret argument. Done means the command remains unchanged and the proposed tests pass.

Written by the indexing model from the issue text.

Description

Area - Formatter

Steps to reproduce

$def = @"
docker build --secret id=NUGET_USER,env=NUGET_USER
"@

Invoke-Formatter -ScriptDefinition $def

Expected behavior

Unchanged:
docker build --secret id=NUGET_USER,env=NUGET_USER

Actual behavior

A whitespace added:
docker build --secret id=NUGET_USER, env=NUGET_USER

Possible tests to repro:

    Context "When a comma is not followed by a space" {
        It "Should not find violation if there are no whitespaces after a comma for a docker command parameter" {
            $def = 'docker build --secret id=NUGET_USER,env=NUGET_USER'
            Invoke-ScriptAnalyzer -ScriptDefinition $def -Settings $settings | Should -Be $null
        }
   }

    Context "When non-PS commands are embedded" {
        It "Docker parameters are kept intact" {
            $def = @"
docker build -t local.rgm-service.image . -f BaseMonitor.Dockerfile --secret id=NUGET_USER,env=NUGET_USER --secret id=NUGET_TOKEN,env=NUGET_TOKEN
"@
            Invoke-Formatter -ScriptDefinition $def | Should -Be $def
        }
