如何从夹具中读取测试函数的文档字符串？

Question

I was trying to get the docstrings of all the test functions from a fixture defined in conftest.py, as shown in the code below, so that they can be analyzed for purposes.

But, from here how can I access the __doc__ attribute of that function when the function is only available as a string ( request.node.name )??

Is there a way to read docstrings through request OR from other default pytest fixtures??

Contents of conftest.py

  1 import pytest
  2 
  3 @pytest.fixture(scope='function', autouse=True)
  4 def publish_to_pubsub(request):
  5     print("\n\nSTARTED Test '{}'".format(request.node.name))
  6     test_name = request.node.name
        // Here -  need to get the docstring of this function . 
  7     
  9     def fin():
 12         print("COMPLETED Test '{}'\n".format(request.node.name))
 13 
 14     request.addfinalizer(fin)

Answer 1

Figured it out.

Reference: docs.pytest.org/en/6.2.x/reference.html#request

print(request.function.__doc__)
