Testing Local Database Migration

notes: right now, room is configured but not used for default.

This boilerplate using Room to store Local Database, to handle each migration you can refer to existing sample. In this sample we add new column in existing table.

• After first project build, make sure database schemas generated for 1st version, it should be located in YOUR_PROJECT_DIR\app\schemas\YOUR_PACKAGE_PATH.data.AppDatabase\1.json, if its not exist, try to rebuild the project.

• do changes on this 3 files:

1. AppDatabase.kt

change version number from 1 to 2. (Migration query has been included, MIGRATION_1_2)

2. LocalPokemon.kt

since we adding column, we need update the entity with the new column.

3. AppModule.kt

• add migration query to the database builder, for details you can also check the TODOs.

• then rebuild the project, new schema version should be generated, 2.json

• go to MigrationTest.kt and run test using device or emulator.
