rebem-enzyme v0.4.1

reBEM addons for Enzyme.

Install

npm i -D rebem-enzyme

Overview

In addition to usual Enzyme methods there are few new which lets you search for components by BEM PropTypes instead of selector:

{
    block
    elem
    mods
    mix
}

This object may be called bemjson.

API

:point_right: Examples below illustrates how it work with shallow wrapper just to be short – mount wrapper has absolutely the same methods.

findBEM(bemjson)

In addition to find().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block' },
        BEM({ block: 'block', elem: 'elem' }),
        BEM({ block: 'block2' })
    )
);

console.log(
    wrapper.findBEM({ block: 'block', elem: 'elem' }).length
);
// 1

filterBEM(bemjson)

In addition to filter().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block' },
        BEM({ block: 'block', elem: 'elem' }),
        BEM({ block: 'block2' })
    )
);
const children = wrapper.children();

console.log(
    children.filterBEM({ block: 'block', elem: 'elem' }).length
);
// 1

notBEM(bemjson)

In addition to not().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block' },
        BEM({ block: 'block', elem: 'elem' }),
        BEM({ block: 'block2' })
    )
);
const children = wrapper.children();

console.log(
    children.notBEM({ block: 'block', elem: 'elem' }).length
);
// 1

isBEM(bemjson)

In addition to is().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block', elem: 'elem' })
);

console.log(
    wrapper.isBEM({ block: 'block', elem: 'elem' })
);
// true

closestBEM(bemjson)

In addition to closest().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block', mods: { mod: true } },
        BEM({ block: 'block', elem: 'elem' }),
        BEM({ block: 'block2' })
    )
);
const firstChild = wrapper.children().first();

console.log(
    firstChild.closestBEM({ block: 'block', mods: { mod: true } }).length
);
// 1

someBEM(bemjson)

In addition to some().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block' },
        BEM({ block: 'block', elem: 'elem' }),
        BEM({ block: 'block2' })
    )
);
const children = wrapper.children();

console.log(
    children.someBEM({ block: 'block', elem: 'elem' })
);
// true

everyBEM(bemjson)

In addition to every().

import { BEM } from 'rebem';
import { shallow } from 'rebem-enzyme';

const wrapper = shallow(
    BEM({ block: 'block' },
        BEM({ block: 'block', elem: 'elem' }),
        BEM({ block: 'block2' })
    )
);
const children = wrapper.children();

console.log(
    children.everyBEM({ block: 'block', elem: 'elem' })
);
// false
