Module: VCR::Cassette::Serializers::Compressed

Extended by:
Compressed
Included in:
Compressed
Defined in:
lib/vcr/cassette/serializers/compressed.rb

Overview

The compressed serializer. This serializer wraps the YAML serializer to write compressed cassettes to disk.

Cassettes containing responses with JSON data often compress at greater than 10:1. The tradeoff is that cassettes will not diff nicely or be easily inspectable or editable.
