Mock Redis server for Node unit tests.
Requires Node version 5.7.0 or higher for the newest language features.
I created this project to help unit test an application that I was writing that used Redis for caching. I didn't want to stub out my client library code since I felt that would not be reliable enough, and I didn't want to get to functional/integration tests and find that my code was broken. I wanted to support sentinel and clustering, and couldn't find something that I felt would work, so I wrote this POS.
Call the start method after creating a new instance of the RedisServer class. This method returns an ES6 promise.
const RedisServer = require('redmock');
let redisServer = new RedisServer();
redisServer.start().then((res) => {
// Server is now up
}).catch((err) => {
// Deal with error
});Call the stop method. This method returns an ES6 promise. You do not have to worry about catching errors from this method.
redisServer.stop().then((res) => {
// Server is now stopped
});// require/import needed crap
describe('SomeTestSpec', () => {
let redisServer, underTest;
// Start the server
before((done) => {
redisServer = new RedisServer();
redisServer.start().then((res) => {
done();
}).catch((err) => {
done(err);
});
});
// Stop the server
after((done) => {
redisServer.stop().then((res) => {
done();
});
});
describe('#somemethod()', () => {
beforeEach(() => {
underTest = new UnderTest();
});
it('should test it', () => {
return underTest.somemethod().should.eventually.equal(true);
});
});
});
