Dynamically generate cassette's name

At the moment you have to explicitly name the cassette file in the path parameter when using a decorator:

@vcr.use_cassette('article_header.yaml')
def test_get_article_header_text_from_url():
    # rest of function...
# cassette is saved as 'article_header.yaml'

Is it possible to dynamically generate cassette’s name so it’s taken from the decorated function instead?

@vcr.use_cassette(func_name)
def test_get_article_header_text_from_url():
    # rest of function...
# cassette is saved as 'test_get_article_header_text_from_url.yaml'

@klvbdmh You should be able to do what you want now with this tiny bit of additional configuration:

my_vcr = VCR(path_tranformer=VCR.ensure_suffix('.yaml'))

@kevin1024 I should have held off on putting this in master until you got a chance to take a look at it. I’m pretty happy with how things turned out, but the code is definitely more complicated, and though this is completely backwards compatible, there are some pretty significant changes underneath the hood.

Let me know what you think.
