[Feature]: Model Driven Application Multi Page Support

[Grant-Archibald-MS]

Is your feature request related to a problem? Please describe.

Currently, there is a limitation in testing capabilities for model-driven applications that span across multiple pages. This restriction makes it challenging to perform comprehensive end-to-end testing and ensure the seamless functionality of multi-page applications.

Having the ability to test across multiple pages of a model-driven application would greatly enhance the testing process and help identify issues that may arise from navigation and interactions between different pages.

Describe the solution you'd like

I would like the ability for the query string changes in a model-driven application to trigger a reload of the Power Fx Object model. This feature would facilitate the reloading and updating of the object model based on the query string parameters, enabling more dynamic and flexible testing scenarios. It would improve the testing process by allowing tests to simulate different states and configurations of the application without requiring a full page reload.

Additional context?

I would like the ability for the query string changes in a model-driven application to trigger a reload of the Power Fx Object model.

This feature would facilitate the reloading and updating of the object model based on the query string parameters, enabling more dynamic and flexible testing scenarios. Specifically, it would be beneficial if the ModelDrivenApplicationProvider could be updated to monitor changes in the URL during the TestState_BeforeTestStepExecuted and TestState_AfterTestStepExecuted events, and subsequently call the BuildObjectModel method.

This enhancement will improve the testing process by allowing tests to simulate different states and configurations of the application without requiring a full page reload.
