Last month Microsoft introduced a new release of the Microsoft Graph Developer Proxy. The latest release introduces support for monitoring specific processes, a new plugin allowing testing against rate limiting supported APIs and provides a new OData paging guidance.
In the process of refactoring an internal tool that connects to the Microsoft Graph API I re-worked the process of retrieving an authentication token that is needed for making a request to the MS Graph API.
While refactoring and upgrading one of our internal tools that is using the MS Graph API, I experimented with several techniques to fake API responses to simulate requests without actually hitting the MS Graph Production API.
