You should be using some sort of test framework.

The project is missing a test suite and therefore lacks user trust. I have put together a simple idea of how the tests should be structured.

import {expect} from 'chai'
import Rule from '../src/rule'

function makeRule(value) {
    return new Rule().value(value)
}

function hasErrors(rule) {
    return rule._messages.length > 0
}

describe('Rules', () => {
    describe('integer', () => {
        it('string equivalents are considered integers', () => {
            expect(hasErrors(makeRule('1').integer())).to.be.false
            expect(hasErrors(makeRule('0').integer())).to.be.false
            expect(hasErrors(makeRule('-1').integer())).to.be.false
        })

        it('will fail if a float value is provided', () => {
            expect(hasErrors(makeRule('1.1').integer())).to.be.true
            expect(hasErrors(makeRule('0.').integer())).to.be.true
        })

        it('empty values are considered invalid', () => {
            expect(hasErrors(makeRule(null).integer())).to.be.true
        })
    })
})

Let me know if this is something you would want to expand upon and can even help write and run the required tests.

You can even add an optional assertion to make the tests more readable:

utils.addProperty(chai.Assertion.prototype, 'errors', function () {
    this.assert(
        this._obj._messages.length > 0,
        'expected #{this} to have errors',
        'expected #{this} to not have errors'
    )
})

it('string equivalents are considered integers', () => {
    expect(makeRule('1').integer()).to.not.have.errors
    expect(makeRule('0').integer()).to.not.have.errors
    expect(makeRule('-1').integer()).to.not.have.errors
})

Hi, thank you for your suggestion!

Frankly speaking, I don't have more time to write the test cases at this moment. Will you be interested to contribute to this project?

Thanks

@semisleep I already made a sample PR #41, take a look and let me know if it is something you are interested in.

Seems like the package is inactive.
