Class: RSpecSolr::SolrResponseHash

Inherits:
Hash
  • Object
show all
Defined in:
lib/rspec-solr/solr_response_hash.rb

Overview

Subclass Hash so we can use RSpec matchers for number of documents:

my_solr_resp_hash.should have(3).documents
my_solr_resp_hash.should have_at_least(3).documents

NOTE: to use has_document?(String) to match documents, set the id_field attribute (defaults to ‘id’)

def doc_matches_all_criteria(doc, expectations_hash)
  expectations_hash.all? do |exp_fname, exp_vals|
    doc.include?(exp_fname) &&
      # exp_vals can be a String or an Array
      # if it's an Array, then all expected values must be present
      Array(exp_vals).all? do |exp_val|

        end
      end
  end
end

#get_first_doc_index(expected_doc) ⇒ Object

Returns the index of the first document that meets the expectations in THIS response.

Examples:

expected_doc Hash implies ALL key/value pairs will be matched in a SINGLE Solr document

{"id" => "666"}
{"subject" => ["warm fuzzies", "fluffy"]}
{"title" => "warm fuzzies", "subject" => ["puppies"]}

expected_doc String

"666"  implies  {'id' => '666'}  when id_field is 'id'

expected_doc Array

["1", "2", "3"]  implies we expect Solr docs with ids 1, 2, 3 included in this response
[{"title" => "warm fuzzies"}, {"title" => "cool fuzzies"}]  implies we expect at least one Solr doc in this response matching each Hash in the Array

Parameters:

  • expected_doc —

    what should be matched in a document in THIS response

Returns:

  • the index of the first document that meets the expectations in THIS response

#has_document?(expected_doc, max_doc_position = nil, all_must_match = nil) ⇒ Boolean

Returns true if THIS Solr Response contains document(s) as indicated by expected_doc.

Examples:

expected_doc Hash implies ALL key/value pairs will be matched in a SINGLE Solr document

{"id" => "666"}
{"subject" => ["warm fuzzies", "fluffy"]}
{"title" => "warm fuzzies", "subject" => ["puppies"]}

expected_doc String

"666"  implies  {'id' => '666'}  when id_field is 'id'

expected_doc Array

["1", "2", "3"]  implies we expect Solr docs with ids 1, 2, 3 included in this response
[{"title" => "warm fuzzies"}, {"title" => "cool fuzzies"}]  implies we expect at least one Solr doc in this response matching each Hash in the Array
[{"title" => /rm fuzz/}, {"title" => /^cool/}]  implies we expect at least one Solr doc in this response matching each Hash in the Array

Parameters:

  • expected_doc —

    what should be matched in a document in THIS response

  • max_doc_position (FixNum) (defaults to: nil) —

    maximum acceptable position (1-based) of document in results. (e.g. if 2, it must be the 1st or 2nd doc in the results)

Returns:

  • (Boolean) —

    true if THIS Solr Response contains document(s) as indicated by expected_doc
