method

in

@Test
public void wal() throws IOException {
 SafeHelperFactory factory=
  SafeHelperFactory.fromUser(new SpannableStringBuilder(PASSPHRASE));
 SupportSQLiteOpenHelper helper=
  factory.create(InstrumentationRegistry.getTargetContext(), DB_NAME,
   new Callback(1));
 SupportSQLiteDatabase db=helper.getWritableDatabase();
 assertFalse(db.isWriteAheadLoggingEnabled());
 assertTrue(db.enableWriteAheadLogging());
 assertTrue(db.isWriteAheadLoggingEnabled());
 db.close();
 factory=SafeHelperFactory.fromUser(new SpannableStringBuilder(PASSPHRASE));
 helper=
  factory.create(InstrumentationRegistry.getTargetContext(), DB_NAME,
   new Callback(1));
 db=helper.getWritableDatabase();
 assertTrue(db.isWriteAheadLoggingEnabled());
 db.disableWriteAheadLogging();
 assertFalse(db.isWriteAheadLoggingEnabled());
 db.close();
}

@Test
public void notQuiteAsSafeButStillNice() {
 final Context ctxt=InstrumentationRegistry.getTargetContext();
 android.database.sqlite.SQLiteOpenHelper helper = new LessSafeNonRoomHelper(ctxt);
 helper.getWritableDatabase();
 helper.close();
 ImportingLessSafeDatabase room = ImportingLessSafeDatabase.gimme(ctxt);
 SupportSQLiteDatabase db=room.getOpenHelper().getWritableDatabase();
 try {
  assertTrue(db.isWriteAheadLoggingEnabled());
 }
 finally {
  room.close();
 }
}

@Test
public void safe() {
