Nightwatch
进程继续运行
我认为这可能与我如何在nightwatch
过程中观看事件有关,但据我所知,我正在观看所有表明nightwatch正在退出的事件
永远不会调用runner.js
中的方法shutdown()
。测试结束后,我如何让夜间值班终止
更新
如果我删除了sign-in.js中的最后一个测试,那么Nightwatch将按预期退出

登录.js(测试之一)
测试成功完成后,我看到以下内容:
grimlock:backend egillespie$ ps -ef | grep nightwatch
501 13087 13085 0 1:51AM ttys000 0:02.18 node ./node_modules/.bin/nightwatch --presets es2015,stage-0 --config e2e/nightwatch.conf.js --env chrome
我没有明确关闭Firebase连接。这导致最后一次测试无限期挂起
以下是我在执行测试清理后关闭连接的方式:
browser.end(() => {
destroyUser(user).then(() => {
firebase.app().delete()
})
})
destroyUser
函数现在如下所示:
function destroyUser (user) {
if (!user) return Promise.resolve()
let db = firebase.database()
return Promise.all([
db.ref('roles').child(user.uid).remove(),
db.ref('users').child(user.uid).remove(),
firebase.auth().deleteUser(user.uid)
])
}
我尝试过以下方法:
在“nightwatch.conf.js”中
“测试设置”{
“默认值”{
“沉默”:没错,
...
},
...
}
我将“静默”从true
设置为false
这会导致控制台变得冗长。运行测试后,chromedriver.exe将和平退出
import firebase from 'firebase-admin'
import uuid from 'uuid'
import * as firebaseSettings from '../../../backend/src/firebase-settings'
const PASSWORD = 'toomanysecrets'
function createUser (user) {

let db = firebase.database()
return Promise.all([
firebase.auth().createUser({
uid: user.uid,

emailVerified: true,
displayName: user.fullName,

}),
db.ref('users').child(user.uid).set({

db.ref('roles').child(user.uid).set({

])
}
function destroyUser (user) {
if (!user) return
console.log('Removing user', user.uid)

我使用的vue模板来自:
我的平台:
- Windows 7(64位)
- 节点v8.1.3
- “夜视”:“^0.9.16”
- “selenium服务器”:“^3.6.0”
- “chromedriver”:“^2.33.1”
在我的情况下(带vue/vuetify的夜视),每次测试后如下所示:
afterEach:function(browser,done){
done();
}
毕竟(异步()=>{
等待关闭会话();
等待stopWebDriver();
}
将其放入配置文件@Erik GillespieNightwatch的浏览器仍存在此问题。end() 如果使用node.js运行Nightwatch,则可以停止进程 通过这样做:
browser.end(() => {
process.exit();
});
它将关闭浏览器并结束进程。如何从控制台终止它?@zero_cool我正在使用
killall node
,但更安全的方法是使用kill
,其中
是node命令的进程(我最初的问题是13087)。
