$ npm i --save mizUsage
import { M } from 'miz'; // ES6
const m = M.arrayOf(M.shape({
id: M.number(10000, 1000000), // id is between 10000 ~ 1000000.
name: M.string(6), // 6 length random string.
sex: M.bool(), // random true or false.
city: M.constant('hz'), // constant value.
work: M.oneOf(['QA', 'FED']) // random from array
}), 2); // list length is 2.
m.mock();Then will get the mock variable like below:
[{
id: 757852,
name: 'mU7RTB',
sex: false,
city: 'hz',
work: 'FED'
}, {
id: 359987,
name: 'jWuKxX',
sex: true,
city: 'hz',
work: 'FED'
}]API & Mocker
You can assemble the variable structure arbitrarily by using the mockers below:
- M.bool()
M.bool().mock(); // true- M.number(min[, max = min, fixed = 0])
M.number(1, 9, 2).mock(); // 4.71- M.string([len = 8])
M.string(6).mock(); // `Qv_teE`- M.constant(value)
M.constant('hello, hustcc.').mock(); // `hello, hustcc`
M.constant(null).mock(); // got null- M.oneOf(valueArray)
M.oneOf(['hustcc', 'imcxl']).mock(); // hustcc- M.arrayOf(mocker[, min = 20, max = min])
// got an array which contains string, and array length 10 ~ 20.
M.arrayOf(VT.string(4), 10, 20);.mock(); - M.shape(mockerObject)
// random value object.
M.shape({
name: M.string(10),
id: M.number(10000, 1000000),
sex: M.bool(),
city: 'hz',
}).mock();- M.apply(Function)
// will got number generate by fucntion Math.random()
M.apply(() => Math.random()).mock(); More
