Decode compressed response

When the :decode_compressed_response option is set to a truthy value, VCR
will decompress "gzip" and "deflate" response bodies before recording. This
ensures that these interactions become readable and editable after being
serialized.

This option should be avoided if the actual decompression of response bodies
is part of the functionality of the library or app being tested.

Background

Given

a file named "decompress.rb" with:

require 'zlib'
require 'stringio'

$server = start_sinatra_app do
  get('/') {
    content = 'The quick brown fox jumps over the lazy dog'
    io = StringIO.new

    writer = Zlib::GzipWriter.new(io)
    writer << content
    writer.close

    headers['Content-Encoding'] = 'gzip'
    io.string
  }
end

require 'vcr'

VCR.configure do |c|
  c.cassette_library_dir = 'cassettes'
  c.hook_into :webmock
  c.default_cassette_options = { :serialize_with => :syck }
end

Scenarios

The option is not set by default

When

I append to file "decompress.rb":

VCR.use_cassette(:decompress) do
  Net::HTTP.start('localhost', $server.port) do |http|
    http.get('/', 'accept-encoding' => 'identity')
  end
end

And

I run ruby decompress.rb

Then

the file "cassettes/decompress.yml" should contain a YAML fragment like:

Content-Encoding:
- gzip

The option is enabled

When

I append to file "decompress.rb":

VCR.use_cassette(:decompress, :decode_compressed_response => true) do
  Net::HTTP.start('localhost', $server.port) do |http|
    http.get('/', 'accept-encoding' => 'identity')
  end
end

And

I run ruby decompress.rb

Then

the file "cassettes/decompress.yml" should contain a YAML fragment like:

Content-Length:
- '43'

And

the file "cassettes/decompress.yml" should contain:

string: The quick brown fox jumps over the lazy dog
