稳住

最简单 sinon.stub( ) (中文( ) ) 备选案文。 支持显示 diff 在 calleddWith。 。 。 .

安装

npm i @cloudcmd/stub

API 密码

stub( 缩写)

• impl - 支架执行

import {stub} from '@cloudcmd/stub';

const fn = stub();

// fn contains stubbed function
const asyncFn = stub(async () => {
    throw Error('hi');
}); // asyncFn contains stub async function

stub (). 返回([值])

const fn = stub().returns('hello');
fn();
// returns
'hello';

stub (. srows ([ 错误])

const fn = stub().throws(Error('hello'));
fn();

// throws
Error('hello');

stub (). rejects ([error]) (中文(简体) )

const fn = stub().rejects(Error('hello'));
await fn();

// rejects
Error('hello');

stub (. resolves ([值])

const fn = stub().resolves('hello');
await fn();
// resolves
'hello';

stub (). called With ([args]) (德语)

const fn = stub();

fn('hello', 'world');

fn.calledWith('hello', 'world');
// returns true

stub (). 称为 With New ()

const fn = stub();

new fn();

fn.calledWithNew();
// returns
true;

stub (). 之前称为 (fn)

const fn1 = stub();
const fn2 = stub();

fn1();
fn2();

fn1.calledBefore(fn2);
// returns
true;

stub (). 称为 After( fn)

const fn1 = stub();
const fn2 = stub();

fn1();
fn2();

fn2.calledAfter(fn1);
// returns
true;

stub( ). 所谓的

const fn = stub();

fn.called;
// returns
false;

fn();

fn.called;
// returns
true;

stub (.). callCount (英语)

const fn = stub();

fn.callCount;

// returns
0;

fn();

fn.callCount;

// returns
1;

stub (. args) (英语)

const fn = stub();

fn.args;
// returns
[];

fn(1);

fn.args;
// returns
[
    [1],
];

stub (. callId) (英语)

每个 stub 拿着 callId,用于确定 stub 电话:

const fn1 = stub();
const fn2 = stub();

fn1();
fn2();

fn1.callId;

// returns
1;

fn2.callId;

// returns
2;

是斯图( fn)

检查是否提供了函数为 stub .

const {stub, isStub} = require('@cloudcmd/stub');
const fn = stub();

isStub(fn);
// returns
true;

isStub(() => {});
// returns
false;
