// 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.
