Writing files

When a code-block contains a filename option, the content of the code block is written to the file specified as a parameter for the option. For example, ```python filename=uuid4.py.

from uuid import uuid4;

print(str(uuid4()))

If the file path contains directories, the directories are created automatically.

If the same filename is used again, the content of the code block is appended to the file.

The filepath is always treated as relative to the workspace of the test case.

nameserver 1.1.1.1

The created files can be used by later code blocks. For example, we could run the python script and print the text files defined in the above code blocks:

python3 uuid4.py
cat a/b/c/d.txt
cat ./etc/resolv.conf

The filename option overrides the default behavior of the code-block. I.e., sh code-blocks are not executed if filename option is defined and env blocks will not set environment variables if filename option is defined.
