assert-easy

a library of deep data type test

Installing

$ npm install assert-easy --save

Usage

var assert = require('assert-easy')

type test

assert.type({})
// 'Object'

assert.is([], 'Array')
// true

bewteen Null and Undefined

assert.meaningless(null)
// true
assert.meaningless(undefined)
// true

As long as there is one in line with expectations.

var data = []
assert.some(data, ['Array', 'Number', 'String'])
// true
assert.some(data, ['Number', 'String'])
// false

Whether the chain of data exists.

var data = {
    a: {
        b: {
            c: 'hello'
        }
    }
}
assert.expect(data, 'a.b.c')
// true
assert.expect(data, 'a.b.c.d')
// false

Expect the type of data chain.

assert.expect(data, 'a.b.c', 'String')
// true
assert.expect(data, 'a.b.c.d', 'String')
// false

Data chain information.

assert.chain(data, 'a.b.c')
/* {
    breakPoint: undefined,
    breakPointType: undefined,
    breakPointValue: undefined,
    done: true,
    type: 'String',
    value: 'hello'
} */
assert.chain(data, 'a.b.c.d')
/* {
    breakPoint: 'c',
    breakPointType: 'String',
    breakPointValue: 'hello',
    done: false,
    type: undefined,
    value: undefined

prop	type	detail
done	{boolean}	Whether the last attribute exists.
value	{any}	the last attribute value.
breakPoint	{string}	Interrupt the attribute name of the chain.
breakPointType	{string}	Interrupt the attribute type of the chain.
