The 'CannotOverwriteExistingCassetteException' exception now takes two kwargs, cassette and failed requests, in order to get the request(s) in the cassettes with the less differences and put those details in the exception message.
In order to use the new assert mechanism that returns explicit assertion failure message, all the default matchers does not return a boolean, but only do an assert statement with a basic assertion message (value_1 != value_2).
The requests_match function has been refactored to use the 'get_matchers_results' function in order to have explicit failures that are logged if any.
Many unit tests have been changed as the matchers does not return a boolean value anymore.
Note: Only the matchers "body" and "raw_body" does not have an assertion message, the body values might be big and not useful to be display to spot the differences.
The function returns two list:
- the first one is the list of matchers names that have succeeded.
- the second is a list of tuples with the failed matchers names and the related assertion message like this ("matcher_name", "assertion_message").
If the second list is empty, it means that all the matchers have passed.
A matcher can now return other results than a boolean :
- An AssertionError exception meaning that the matcher failed, with the exception we get the assertion failure message.
- None, in case we do an assert in the matcher, meaning that the assertion has passed, the matcher is considered as a success then.
- Boolean that indicates if a matcher failed or not. If there is no match, a boolean does not give any clue what it is the differences compared to the assertion.
When I ran the test suite on macOSX, I had some issues regarding SSL configuration, I have documented the error I encounter and the solution to deal with it.
The error we have : SSLError: hostname '127.0.0.1' doesn't match either of 'localhost', '127.0.0.1'
This is fixed by adding the `ipaddress` dependency in the tox ini.
In versions of Python from 3.8 and forward, importing Mapping and
MutableMapping from the collections module will no longer work. This
change will try to import from the collections.abc module, which was
added in Python 3.3, and fall back to the collections module on older
versions of Python.
