Suppress pytest warnings for other peoples code only

Question

I'm trying out pytest for the first time. How do I suppress warnings issued about other peoples code that my code depends on without suppressing warnings about my own code?

Right now I have this in my pytest.ini so I don't have to see pytest warn me about some deprecation on the jsonschema package that I'm using.

[pytest]
filterwarnings =
    ignore::DeprecationWarning

But now if I write anything in my own code that should fire of a deprecation warning I'll miss it.

The syntax for pytest-warning is action:message:category:module:lineno. You can use this config for ignoring only jsonschema:

[pytest]
filterwarnings =
    ignore::DeprecationWarning:jsonschema

You can also use regex in those fields. If you want to exclude all warnings except yours:

[pytest]
filterwarnings =
    ignore::DeprecationWarning:!yourtestmodule

Pytest uses the same filterwarning as python. You can learn more about python warnings here: https://docs.python.org/3/library/warnings.html#warning-filter
