A simple mock interface specifically for testing code relying on Sequelize models
npm install sequelize-mockA mocking interface designed for testing code that uses Sequelize.
Documentation at sequelize-mock.readthedocs.io

npm i sequelize-mock --save-dev
The Mock Models created with this library function as drop in replacements for your unit testing.
Start by importing the library
`javascript`
var SequelizeMock = require('sequelize-mock');
Initialize the library as you would Sequelize
`javascript`
var DBConnectionMock = new SequelizeMock();
Define your models
`javascript`
var UserMock = DBConnectionMock.define('users', {
'email': 'email@example.com',
'username': 'blink',
'picture': 'user-picture.jpg',
}, {
instanceMethods: {
myTestFunc: function () {
return 'Test User';
},
},
});
Once Mock models have been defined, you can use them as drop-in replacements for your Sequelize model objects. Data is not retrieved from a database and instead is returned based on the setup of the mock objects, the query being made, and other applied or included information.
For example, your code might look something like this
`javascriptuser
UserMock.findOne({
where: {
username: 'my-user',
},
}).then(function (user) {
// is a Sequelize Model-like objectwhere
user.get('id'); // Auto-Incrementing ID available on all Models
user.get('email'); // 'email@example.com'; Pulled from default values
user.get('username'); // 'my-user'; Pulled from the in the query``
user.myTestFunc(); // Will return 'Test User' as defined above
});
This library is under active development, so you should feel free to submit issues, questions, or pull requests.
