assertify

Automatically generates chai assertions.

For lazy developers that want to quickly write their unit tests.

Example

var assertify = require('assertify');

// Given a variable you want to make assertions for
var store = {
    id: '3605',
    name: 'Fnac Preciados',
    street: 'Calle Preciados, 28',
    zip: '28013',
    city: 'Madrid',
    latitude: 40.419027,
    longitude: -3.705254,
    openingTimes: [{
        date: 1439456166345,
        time: '08:00 - 20:00',
        today: true
    }],
    type: 'store',
    homeStore: false,
    newStore: true
};

// Just assertify it
assertify(store, { variableName: 'store' });

// The console will output:
chai.expect(store).to.be.an('object');
chai.expect(store).to.have.keys('id', 'name', 'street', 'zip', 'city', 
    'latitude', 'longitude', 'openingTimes', 'type', 'homeStore', 'newStore');
chai.expect(store.id).to.be.a('string');
chai.expect(store.id).to.be.eql('3605');
chai.expect(store.name).to.be.a('string');
chai.expect(store.name).to.be.eql('Fnac Preciados');
chai.expect(store.street).to.be.a('string');
chai.expect(store.street).to.be.eql('Calle Preciados, 28');
chai.expect(store.zip).to.be.a('string');
chai.expect(store.zip).to.be.eql('28013');
chai.expect(store.city).to.be.a('string');
chai.expect(store.city).to.be.eql('Madrid');
chai.expect(store.latitude).to.be.a('number');
chai.expect(store.latitude).to.be.eql(40.419027);
chai.expect(store.longitude).to.be.a('number');
chai.expect(store.longitude).to.be.eql(-3.705254);
chai.expect(store.openingTimes).to.be.an('array');
chai.expect(store.openingTimes).to.have.length(1);
chai.expect(store.openingTimes[0].date).to.be.a('number');
chai.expect(store.openingTimes[0].date).to.be.eql(1439456166345);
chai.expect(store.openingTimes[0].time).to.be.a('string');
chai.expect(store.openingTimes[0].time).to.be.eql('08:00 - 20:00');
chai.expect(store.openingTimes[0].today).to.be.a('boolean');
chai.expect(store.openingTimes[0].today).to.be.eql('true');
chai.expect(store.type).to.be.a('string');
chai.expect(store.type).to.be.eql('store');
chai.expect(store.homeStore).to.be.a('boolean');
chai.expect(store.homeStore).to.be.eql('false');
chai.expect(store.newStore).to.be.a('boolean');
chai.expect(store.newStore).to.be.eql('true');

Usage

assertify(variable, options)

Arguments

• variable - Anything you want to make assertions for
• options - An optional object defining a number of options:
  • variableName - The variable name to render, by default 'foo'
  • includeTypes - Whether to include assertions to check the value type, by default true
  • console - If truthy, will console.log the chai assertions. Can also be a function in case you want custom logging. By default false.
