chai-arrays

一個簡單的 chai 外掛，用於更好的陣列斷言

安裝

npm install chai-arrays

使用方式

外掛程式

const chai = require('chai');
const assertArrays = require('chai-arrays');
chai.use(assertArrays);

array

斷言 actual 的型別為 Array。

expect([1, 2, 3]).to.be.array();
expect('foobar').not.to.be.array();

expect(new Uint8Array([1])).to.be.Uint8Array();
expect(new Uint16Array([1])).to.be.Uint16Array();
expect(new Uint32Array([1])).to.be.Uint32Array();
expect(new Uint8ClampedArray([1])).to.be.Uint8ClampedArray();

ofSize

斷言 actual 的大小等於 expected。

expect([1, 2, 3]).to.be.ofSize(3);
expect([1, 2, 3]).not.to.be.ofSize(5);

equalTo

斷言 actual 等於 expected。

expect([1, 2, 3]).to.be.equalTo([1, 2, 3]);
expect([1, 2, 3]).not.to.be.equalTo([1, 2, 5]);

containing

斷言 actual 包含 expected 元素。

expect([1, 2, 3]).to.be.containing(1);
expect([1, 2, 3]).not.to.be.containing(5);

containingAllOf

斷言 actual 包含所有 expected 的元素。

expect([1, 2, 3]).to.be.containingAllOf([1]);
expect([1, 2, 3]).to.be.containingAllOf([1, 3]);
expect([1, 2, 3]).to.be.containingAllOf([1, 2, 3]);

containingAnyOf

斷言 actual 包含任何 expected 的元素。

expect([1, 2, 3]).to.be.containingAnyOf([1]);
expect([1, 2, 3]).to.be.containingAnyOf([6, 7, 3, 5]);
expect([1, 2, 3]).to.be.containingAnyOf([1, 2, 3]);

sorted

斷言 actual 陣列已排序。

expect([1, 2, 3]).to.be.sorted();
expect([1, 2, 4, 3]).not.to.be.sorted();

expect([3, 2, 1]).to.be.sorted((prev, next) => prev < next); // sorting based on the provided function
