Is there any way to check integrity of the database at the start up, so that we can create new database if there any issue?

I am trying to test room database migration on robolectric . Robolectric version used 4.4. I am facing java.io.FileNotFoundException: Cannot find the schema file in the assets folder. Make sure to include the exported json schemas in your test assert inputs. See https://developer.android.com/training/data-storage/room/migrating-db-versions#export-schema for details

Eventhough 1.json file present .

build.gradle :

javaCompileOptions {
annotationProcessorOptions {
arguments = ["room.schemaLocation": "$projectDir/build/schemas".toString()]
}
}

sourceSets {
release.assets.srcDirs += files("$projectDir/build/schemas".toString())
}

testImplementation "androidx.room:room-testing:2.2.6"

Unit test code:

private static final String TEST_DB = "migration-test";

MigrationTestHelper helper = new MigrationTestHelper(InstrumentationRegistry.getInstrumentation(), ld + (MyDatabase.class.getCanonicalName()));
SupportSQLiteDatabase db = helper.createDatabase(TEST_DB, 1);

// Prepare for the next version.
db.close();

// Re-open the database with version 2 and provide
// MIGRATION_1_2 as the migration process.
db = helper.runMigrationsAndValidate(TEST_DB, 2, true, MyDatabase.MIGRATION_1_2);
