Redis client mock object for unit testing
npm install redis-mockredis-mock
============
!Build status
!node-current
!mock-completeness-red)
The goal of the redis-mock project is to create a feature-complete mock of node_redis, which may be used interchangeably when writing unit tests for code that depends on redis.
All operations are performed in-memory, so no Redis installation is required.
100% Redis-compatible (see Cross Verification)
```bash``
$ npm install redis-mock --save-dev
The below code demonstrates a example of using the redis-mock client in node.js/io.js
`js`
var redis = require("redis-mock"),
client = redis.createClient();
Currently implemented are the following redis commands:
or AGGREGATE yet)
* zinterstore (Partial: no support for WEIGHTS or AGGREGATE yet)
* zscore$3
* flushdb
* flushall
* time
Cross verification
If you want to add new tests to the test base it is important that they work too on node_redis (we are creating a mock...).
You can therefore run the tests using
redis instead of redis-mock. To do so:``bash
$ npm test:valid
``You will need to have a running instance of
on you machine and our tests use flushdb a lot so make sure you don't have anything important on it.
Roadmap
redis-mock is work in progress, feel free to report an issueExample usage
Jest
In order to make sure that your tests use the
redis-mock instead of the actual redis implementation,
update your jest.config.js, by adding setupFileAfterEnv, as follows:`javascript
module.exports = {
// other properties...
setupFilesAfterEnv: ['./jest.setup.redis-mock.js'],
};
`From this point on, jest will always trigger the content of
before the execution of all tests.Now, let's create the file
jest.setup.redis-mock.js in the same directory as jest.config.js and paste the following
content:`javascript
jest.mock('redis', () => jest.requireActual('redis-mock'));
`This will make sure that the actual
is never loaded and whenever any file tries to import/require redis,
redis-mock` will be returned instead.Copyright (c) 2012 Kristian Faeldt
