There are many similar assertions that verify if the author is visible. I suggest to create a dedicated assertion helper method to make the tests more expressive and get rid of some duplication:

```python
def assert_entry_visible_author(entry)
def assert_entry_hidden_author(entry)
```

or 

```python
def assert_author_visibility(entry, visibility)
# assert_author_visibility(entry, True)
# assert_author_visibility(entry, False)
```
