Possible to just run pytest on open buffer without modifying is_test_file?

If I have a python file like foo.py that does not end or start with test_ but contains test methods that start with test_, is there a way to just run pytest on the current buffer, like what !pytest "%" would do basically, but via Neotest. I understand I could provide my own is_test_file function that scans python files for test_ method but wondering if there is a way to force Neotest to consider the active buffer a test file and just run pytest on it on an as-needed basis.

Start by tracing how neotest-python identifies test files and how Neotest runs the current buffer. Check whether an existing buffer-level or adapter-level entry point can bypass is_test_file, then verify the behavior with a Python buffer named foo.py containing test_ methods; done means the buffer runs through pytest without changing file detection.
