PSProxmoxVE/tests/dev.ps1

#Requires -Version 5.1
<#
.SYNOPSIS
    Helper script for the dev/test containers.

.DESCRIPTION
    Manages Docker-based dev containers for building, testing, and running
    integration tests for PSProxmoxVE. Works on Windows, macOS, and Linux.

    Use switches to compose actions: -Provision -Integration -Cleanup can
    be combined in a single invocation.

    For x86-only commands (integration, provision, cleanup), use -DockerHost
    to run containers on a remote Docker host via SSH. The script syncs the
    repo to the remote host automatically.

.PARAMETER Shell
    Open an interactive pwsh shell in the dev container.

.PARAMETER Build
    Build the module inside the container.

.PARAMETER Test
    Run unit tests (Pester, excluding Integration tag).

.PARAMETER Provision
    Provision nested PVE VMs (x86 only). Required before -Integration
    unless VMs are already running.

.PARAMETER Integration
    Run integration tests against provisioned PVE VMs.

.PARAMETER Cleanup
    Destroy provisioned VMs (x86 only).

.PARAMETER Stop
    Stop all containers.

.PARAMETER Rebuild
    Rebuild container images from scratch.

.PARAMETER Tests
    Filter integration tests by area name. Comma-separated list of test
    area names that match the numbered file prefixes. Examples:
        -Tests Connection,Nodes     # runs 00_Connection + 01_Nodes
        -Tests VMs,Snapshots        # runs 06_VMs + 07_Snapshots
        -Tests Cluster              # runs 16_Cluster
    When omitted, all integration test files are run.

.PARAMETER Version
    PVE version to test against (8, 9, or all). Default: all.

.PARAMETER DockerHost
    SSH destination for a remote Docker host (e.g. 172.16.40.113).

.PARAMETER NoCleanup
    When used with -Integration, skips cleanup after tests complete.

.EXAMPLE
    ./tests/dev.ps1 -Shell
    # Opens a pwsh shell in the dev container

.EXAMPLE
    ./tests/dev.ps1 -Build -Test
    # Builds the module and runs unit tests

.EXAMPLE
    ./tests/dev.ps1 -Provision -Integration -Cleanup -DockerHost 172.16.40.113
    # Full lifecycle: provision, test, cleanup on remote host

.EXAMPLE
    ./tests/dev.ps1 -Integration -Tests Connection,VMs -Version 9 -DockerHost 172.16.40.113
    # Run only Connection and VMs integration tests for PVE 9

.EXAMPLE
    ./tests/dev.ps1 -Provision -Integration -Tests Cluster,HA -Version 9 -Cleanup -DockerHost 172.16.40.113
    # Provision, run cluster+HA tests for PVE 9, cleanup
