ESTester

ESTester is a Python package to help testing ElasticSearch queries.

It provides a TestCase which allows you to load data to a test index and validate the behavior of your search queries.

How to install

Using pip to install from Cheeseshop

pip install estester

Or, install from the source

git clone git://github.com/tatiana/estester.git
python setup.py install

How to use

ESTester defines a main testing class, called ElasticSearchQueryTestCase.

In order to use it, you should subclass it and redefine one or more class attributes:

• index: name of the index (default: sample.test)
• host: ElasticSearch host (default: http://localhost:9200/)
• fixtures: list of items to be loaded (default: [])
• timeout: time in seconds to wait index load (default: 5s)
• reset_index: delete index after running tests (default: True)

Basic example, only re-defining fixtures:

from estester import ElasticSearchQueryTestCase

SAMPLE_QUERY = {
    "query": {
        "query_string": {
            "fields": [
                "name"
            ],
            "query": "nina"
        }
    }
}

class QueryTestCase(ElasticSearchQueryTestCase):

    fixtures = [
        {
            "type": "dog",
            "id": "1",
            "body": {"name": "Nina Fox"}
        },
        {
            "type": "dog",
            "id": "2",
            "body": {"name": "Charles M."}
        }
    ]

    def test_query_by_nina_returns_one_result(self):
        response = self.search(SAMPLE_QUERY)
        self.assertEqual(response["hits"]["total"], 1)
        self.assertEqual(response["hits"]["hits"][0]["_id"], u"1")
        self.assertEqual(response["hits"]["hits"][0]["_source"], {u"name": u"Nina Fox"})
