# Tool Validation

### Testing the RAS Custom Provider Script

The Custom Provider Test Framework is a PowerShell-based validation toolkit for testing RAS Custom Provider scripts outside the RAS Console. It helps script authors verify both low-level protocol methods and higher-level workflows such as template creation, maintenance mode operations, and host creation.

### Purpose

The framework is intended to make development and troubleshooting easier by letting you send the same kinds of requests that RAS sends to a custom provider script. This allows you to validate script behavior before integrating it into a live RAS workflow. The tests cover connection handling, guest enumeration, guest control, template conversion, cloning, snapshot operations, and asynchronous task polling.

### Framework structure

The test framework includes these core files:

* `CustomProvider.psd1` — main configuration file used to define how the provider script should be launched and which custom settings should be passed to it.
* `CustomProvider.psm1` — supporting module used by the test scripts.
* `Individual Test-*.ps1` scripts — each script exercises a specific provider method or higher-level workflow.
