#Requires -Version 7
<#
.SYNOPSIS
  End-to-end tests against a running Podman API via MaksIT.PodmanClientDotNet.PowerShell.

.DESCRIPTION
  Builds the module, connects with PODMAN_TEST_URL, then runs scenarios from scenarios\Scenario-*.ps1.

  Filter:
    pwsh -File .\src\e2e-tests\Test-PodmanE2E.ps1 -Scenario 'System'
    pwsh -File .\src\e2e-tests\Test-PodmanE2E.ps1 -Scenario '*Image*','*Container*'

.EXAMPLE
  $env:PODMAN_TEST_URL = 'http://192.168.2.128:8080'
  pwsh -File .\src\e2e-tests\Test-PodmanE2E.ps1
