[英]Electron app opening multiple windows or processes in spectron test
我的 electron 應用程序按預期工作,但是當我運行 Spectron 測試以測試 windows 打開的數量時,它會繼續打開新的 windows。
Electron 版本 - v8.0.2,“spectron”:“^10.0.1”。 我不確定如何檢查 spectron 的確切版本。 我只是在運行一個小演示,下面我將給出代碼片段
注意:我正在運行由 electron-packager 生成的指向 .exe 文件的 spectron 測試。
如果可能的話,有誰知道問題是什么?
main.js
const { app, BrowserWindow } = require('electron')
function createWindow () {
let win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true
}
})
win.loadFile('index.html')
}
app.whenReady().then(createWindow)
index.js
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Hello World!</title>
<meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline';" />
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>
測試.js
const assert = require('assert');
const path = require('path');
const Application = require('spectron').Application;
const electronPath = require('electron');
const app = new Application({
path: 'C:/demoElectronApp/winx64/demoelectronapp-win32-x64/demoelectronapp.exe',
});
describe('client_settings_app', function () {
this.timeout(10000);
beforeEach(() => {
return app.start();
});
it('shows only one initial window', async () => {
const count = await app.client.getWindowCount();
return assert.equal(count, 1);
});
})
package.json
{
"name": "demoelectronapp",
"version": "1.0.0",
"description": "",
"main": "main.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"electronpackage": "electron-packager . --out winx64"
},
"author": "",
"license": "ISC",
"dependencies": {
"path": "^0.12.7"
},
"devDependencies": {
"electron": "^8.2.2",
"electron-packager": "^14.2.1",
"assert": "^2.0.0",
"mocha": "^7.1.1",
"spectron": "^10.0.1"
}
}
好的,我遇到了同樣的問題。 並通過設置遠程調試端口解決。
chromeDriverArgs: ['remote-debugging-port=9222']
完整的測試代碼:
const Application = require('spectron').Application
const assert = require('assert')
const electronPath = require('electron') // Require Electron from the binaries included in node_modules.
const path = require('path')
describe('Application launch', function () {
this.timeout(10000)
beforeEach(function () {
this.app = new Application({
// Your electron path can be any binary
// i.e for OSX an example path could be '/Applications/MyApp.app/Contents/MacOS/MyApp'
// But for the sake of the example we fetch it from our node_modules.
path: path.join(__dirname, '..', 'node_modules', '.bin', 'electron' + (process.platform === 'win32' ? '.cmd' : '')),
// Assuming you have the following directory structure
// |__ my project
// |__ ...
// |__ main.js
// |__ package.json
// |__ index.html
// |__ ...
// |__ test
// |__ spec.js <- You are here! ~ Well you should be.
// The following line tells spectron to look and use the main.js file
// and the package.json located 1 level above.
args: [path.join(__dirname, '..')],
env: {
ELECTRON_ENABLE_LOGGING: true,
ELECTRON_ENABLE_STACK_DUMPING: true,
NODE_ENV: 'test'
},
waitTimeout: 10e3,
requireName: 'electronRequire',
chromeDriverLogPath: '../chromedriverlog.txt',
chromeDriverArgs: ['remote-debugging-port=9222']
})
return this.app.start()
})
afterEach(function () {
if (this.app && this.app.isRunning()) {
return this.app.stop()
}
})
it('shows an initial window', function () {
return this.app.client.getWindowCount().then(function (count) {
assert.equal(count, 1)
// Please note that getWindowCount() will return 2 if `dev tools` are opened.
// assert.equal(count, 2)
})
})
})
我終於找到了一種對我有用的方法來解決這個問題。 我在@wburgess-invision 對此 gitHub 線程的評論中找到了它: https://github.com/electron-userland/spectron/issues/60
引用線程:“我注意到它的發生是因為傳入了 --enable-logging 參數。所以我制作了一個修改版的 launcher.js,它故意不包含 --enable-logging 並且它運行良好對我們來說。我找不到 spectron 啟動器從哪里獲取 --enable-logging 標志,因為我認為更好的解決方案是首先不將其提供給 launcher.js,但我不能不知道所以我只是選擇了現在有效的解決方案.我的假設是當客戶端初始化並因此調用launcher.bat時--enable-logging標志在webdriverio內部的某個地方被拾取但我不能找出哪里。”
我遇到了類似的問題,並更改了我正在使用的軟件包的版本。 此頁面有版本 map: https://github.com/electron-userland/spectron#version-map
看起來這不是您的問題,可能會幫助其他人。
