#321 Simple integration test was added for DyBase

good question. how about this. we create a test that does something like this:

```
base = new DyBase(...region pointing to the dynamodb local...);
repos = base.repos();
repo = repos.add("test");
task = repo.add(command, ...);
assertThat(task.command(), equalTo(command));
```

then, ignore it and add necessary puzzles. make sense?
