ElasticSearch is an Open Source (Apache 2), Distributed, RESTful, Search Engine built on top of Apache Lucene. It promises to solve all the pain points of implementing search in a web application. Tire is one of the popular ruby clients for elasticsearch. Though it is important to have integration test for models while using tire in a ruby app, it is equally important to make sure that the test doesn't corrupt the development indices.
One approach to overcome this is to create a dummy class in the test that includes the Tire::Model::Search and Tire::Model::Callbacks module and use it to create indices and test search in the integration test. While this seems simple, there is a cleaner approach, that lets us use the actual models in test and does not corrupt the development indices as well. There is a configuration in tire that lets you provide the prefix to the index name. By specifying the
Tire::Model::Search.index_prefix Rails.env
in the initializers/tire.rb file, we can tell tire to use different indices for different environments. For example, the search in the dev mode will use "development_model_name" index and that in the test environment will use "test_model_name" index.
