StrictRedis is deprecated.
Better use Redis instead.

Can we consider one more approach here:

try:
    connection = Connection(
        'sentinel://localhost:65534/',
        transport_options={
            'global_keyprefix': 'some_prefix',
            'master_name': 'not_important',
        },
    )
    with pytest.raises(ConnectionError):
        connection.channel()
finally:
    connection.close()  # Ensure connection is closed even if an exception occurs

Should we consider testing potential exceptions that could occur during connection creation??

These tests are inside a test class. Try:

pytest t/unit/transport/test_redis.py::test_RedisSentinel::test_can_create_connection_with_global_keyprefix

@50-Course

These tests are inside a test class. Try:

pytest t/unit/transport/test_redis.py::test_RedisSentinel::test_can_create_connection_with_global_keyprefix

class test_Redis:

    def setup(self):
        self.connection = Connection(transport=Transport)
        self.exchange = Exchange('test_Redis', type='direct')
        self.queue = Queue('test_Redis', self.exchange, 'test_Redis')

    def teardown(self):
        self.connection.close()

If I am not mistaken it means it does not apply to your connection obj so I agree with a safer approach like @50-Course proposed.

Also, reviewing a sample of the other tests shows most tests have consistent resource cleanup manually, so it would make sense to apply it here as well.
