As a workaround to your original question, realize you can write a file
just as easily as passing an argument to something:

$ pytest --variables-on-cmdline=[[JSON_CONTENTS]]

can become:

$ echo [[JSON_CONTENTS]] > input.json
$ pytest --variables=input.json

But keep in mind this will need careful and complex shell escaping.

I'm sure there is a better ways to accomplish this if you would explain
your use case in more details.

Cheers,
