A helper function to create a mock to replace the use of `open`. It works

for `open` called directly or used as a context manager.
|
|

The `mock` argument is the mock object to configure. If `None` (the
|
|
default) then a `MagicMock` will be created for you, with the API limited
|
|
to methods or attributes available on standard file handles.
|
|
|
|
`read_data` is a string for the `read` methoddline`, and `readlines` of the
|
|
file handle to return. This is an empty string by default.
