# ElasticMock
Python Elasticsearch Mock for test purposes
[](https://travis-ci.org/vrcmarcos/elasticmock) [](https://coveralls.io/github/vrcmarcos/elasticmock?branch=master) [](https://badge.fury.io/py/ElasticMock) [](https://github.com/vrcmarcos/elasticmock/blob/master/LICENSE)  
 [](https://pepy.tech/project/elasticmock/month)
## Installation
```shell
pip install ElasticMock
```
## Usage
To use ElasticMock, decorate your test method with **@elasticmock** decorator:
```python
from unittest import TestCase
from elasticmock import elasticmock
class TestClass(TestCase):
@elasticmock
def test_should_return_something_from_elasticsearch(self):
self.assertIsNotNone(some_function_that_uses_elasticsearch())
```
### Custom Behaviours
You can also force the behaviour of the ElasticSearch instance by importing the `elasticmock.behaviour` module:
```python
from unittest import TestCase
from elasticmock import behaviour
class TestClass(TestCase):
...
def test_should_return_internal_server_error_when_simulate_server_error_is_true(self):
behaviour.server_failure.enable()
...
behaviour.server_failure.disable()
```
You can also disable all behaviours by calling `behaviour.disable_all()` (Consider put this in your `def tearDown(self)` method)
#### Available Behaviours
* `server_failure`: Will make all calls to ElasticSearch returns the following error message:
```python
{
'status_code': 500,
'error': 'Internal Server Error'
}
```
## Code example
Let's say you have a prod code snippet like this one:
```python
import elasticsearch
class FooService:
def __init__(self):
self.es = elasticsearch.Elasticsearch(hosts=[{'host': 'localhost', 'port': 9200}])
def create(self, index, body):
es_object = self.es.index(index, body)
return es_object.get('_id')
def read(self, index, id):
es_object = self.es.get(index, id)
return es_object.get('_source')
```
Than you should be able to test this class by mocking ElasticSearch using the following test class:
```python
from unittest import TestCase
from elasticmock import elasticmock
from foo.bar import FooService
class FooServiceTest(TestCase):
@elasticmock
def should_create_and_read_object(self):
# Variables used to test
index = 'test-index'
expected_document = {
'foo': 'bar'
}
# Instantiate service
service = FooService()
# Index document on ElasticSearch
id = service.create(index, expected_document)
self.assertIsNotNone(id)
# Retrive dpcument from ElasticSearch
document = service.read(index, id)
self.assertEquals(expected_document, document)
```
## Notes:
- The mocked **search** method returns **all available documents** indexed on the index with the requested document type.
- The mocked **suggest** method returns the exactly suggestions dictionary passed as body serialized in Elasticsearch.suggest response. **Atention:** If the term is an *int*, the suggestion will be ```python term + 1```. If not, the suggestion will be formatted as ```python {0}_suggestion.format(term) ```.
Example:
- **Suggestion Body**:
```python
suggestion_body = {
'suggestion-string': {
'text': 'test_text',
'term': {
'field': 'string'
}
},
'suggestion-id': {
'text': 1234567,
'term': {
'field': 'id'
}
}
}
```
- **Suggestion Response**:
```python
{
'suggestion-string': [
{
'text': 'test_text',
'length': 1,
'options': [
{
'text': 'test_text_suggestion',
'freq': 1,
'score': 1.0
}
],
'offset': 0
}
],
'suggestion-id': [
{
'text': 1234567,
'length': 1,
'options': [
{
'text': 1234568,
'freq': 1,
'score': 1.0
}
],
'offset': 0
}
],
}
```
## Testing
```bash
python setup.py test
```
