// TestApp is a simple wrapper around an App. It exposes internal keepers for use in integration tests.
// This file also contains test helpers. Ideally they would be in separate package.
// Basic Usage:
//
//	Create a test app with NewTestApp, then all keepers and their methods can be accessed for test setup and execution.
//
// Advanced Usage:
//
//	Some tests call for an app to be initialized with some state. This can be achieved through keeper method calls (ie keeper.SetParams(...)).
//	However this leads to a lot of duplicated logic similar to InitGenesis methods.
//	So TestApp.InitializeFromGenesisStates() will call InitGenesis with the default genesis state.
//	and TestApp.InitializeFromGenesisStates(authState, cdpState) will do the same but overwrite the auth and cdp sections of the default genesis state
//	Creating the genesis states can be combersome, but helper methods can make it easier such as NewAuthGenStateFromAccounts below.
