Office Add-in Test Server

The `office-addin-test-server` package provides a lightweight local web server specifically designed for testing Office Add-ins. It's a key component within the larger `OfficeDev/Office-Addin-Scripts` ecosystem, offering a framework for add-ins to send test results, which can then be consumed by test runners like Mocha to validate functionality. Currently stable at version 2.0.4, this package facilitates automated testing workflows by acting as a collection point for results from add-in runtime environments. Unlike general-purpose web servers, its differentiation lies in its tight integration with Office Add-in development, simplifying the process of capturing and processing test outcomes from within Office applications.
