node.js - stub 从未使用 chai-as-promised 调用 sinon 和 nodejs
问题描述
我的单元测试遇到问题,完全卡住了,代码很简单,请了解发生了什么,我的存根从未被调用过,集合似乎是正确的,这里是代码:
let strategy = fixtures.load('strategy')
chai.use(chaiAsPromised)
describe.only('Spawn Order Job', () => {
let getPositionsStub, createJobStub, daoStub,sandbox
beforeEach(()=>{
sandbox = sinon.createSandbox()
daoStub = sandbox.stub(dao, 'updateActiveOrders').resolves(true) //async
getPositionsStub = sandbox.stub(strategyModule, 'getPositions') //sync
createJobStub = sandbox.stub(helpers, 'createJob') //sync
createJobStub.returns(true)
getPositionsStub.resolves([{fake:'t'}, {fake:'t'}])
})
afterEach(()=>{
sandbox.restore()
})
//OK
it('Should failed with no param, type error context', ()=> {
const promise = spawnOrderJob()
expect(promise).to.be.rejectedWith(TypeError)
})
//OK
it('Should throw error timeout order', () => {
getPositionsStub.resolves([{fake:'t'}, {fake:'t'}])
strategy.lastDateOrder = new Date()
const ctx = { state: {strategy, dashboard, position:null}}
const action = {b: true, s: false}
const promise = spawnOrderJob(action, ctx)
expect(getPositionsStub.called).to.be.true
expect(daoStub.called).to.be.false
expect(createJobStub.called).to.be.false
expect(promise).to.be.rejectedWith(ORDER_ERROR, 'Timeout between order not expired.')
})
//KO stub never called
it.only('Should pass validation on buy', () => {
strategy.lastDateOrder = 0
const ctx = { state: {strategy, dashboard, position: null }}
const action = {b: true, s: false}
const promise = spawnOrderJob(action, ctx)
expect(promise).to.be.fulfilled
expect(getPositionsStub.called).to.be.true //ok
expect(createJobStub.called).to.be.true //never callled ????
expect(daoStub.called).to.be.true //never called ????
})
})
想了解现在发生了什么,调用是正确的 imo,使用 mocha 5.2 运行
Helpers.js :功能描述如下:
async function spawnOrderJob(action, ctx) {
try {
const { strategy, dashboard, position } = ctx.state
const {b, s} = action
//check in case strategy context
if (strategy) {
//pass validation buy contnext
if (b) {
//this stub is working
const positions = await strategyModule.getPositions(ctx)
const { maxPosition } = strategy.allocatedBTC
const { activeOrders, maxActiveOrders, timeBetweenOrder, lastDateOrder } = strategy
debug('Active orders:', strategy.activeOrders)
debug('Position:', positions.length)
if (activeOrders >= maxActiveOrders)
throw new ORDER_ERROR('Max active orders reach.')
if (positions.length + activeOrders >= maxPosition)
throw new ORDER_ERROR('Max positions reach.')
if (!timeoutExpired(lastDateOrder, timeBetweenOrder))
throw new ORDER_ERROR('Timeout between order not expired.')
//increment active orders counter
//stub fail, but not called at all
await dao.updateActiveOrders(strategy, true)
}
//Sell context
if (s) {
if (!position)
throw new ORDER_ERROR('No position to sell')
}
}
//stub fail, but called internally
return createJob(constants.DASHBOARD_CREATE_ORDER, {
orderType: b ? 'BUY' : 'SELL',
title: `Strategy create order ( ${ b ? 'BUY' : 'SELL'} )`,
strategy,
dashboard,
position
})
} catch (e) {
throw e
}
}
function createJob(name, data){
//shortcut queue.create (kue.js)
return queue.c(name,data)
}
module.exports = {
createJob,
spawnOrderJob
}
道
const updateActiveOrders = async (strategy, increment) => {
try {
const s = await model.findOne({_id: strategy._id})
if (!s) throw new Error('Strategy not found.')
s.activeOrders = increment ? s.activeOrders+1 :s.activeOrders-1
s.lastDateOrder = new Date()
return await s.save()
}catch(e){
throw e
}
}
module.exports = {updateActiveOrders}
