我仅使用基本的Spectron测试文件(在Typescript中)打开我的应用程序,获取窗口计数,然后大概退出。但是,Spectron的app.stop()
似乎只是关闭开发工具窗口,而使主窗口保持运行状态。我到处搜索并遇到一些GitHub问题,遇到这个问题的人。人们似乎提供的最好的方法是使用pkill
。我不想这样做,因为它有可能杀死更多的东西(例如,在CI服务器上)。
在显示所有代码之前,我的问题是,要使Spectron的会话在测试后真正退出,我需要怎么做?
这是我的spec.ts
,其中包含我的测试:
import { Application } from "spectron";
import * as assert from "assert";
import * as electronPath from "electron";
import * as path from "path";
describe('Application launch', function () {
this.timeout(10000);
beforeEach(function () {
this.app = new Application({
path: electronPath,
args: [path.join(__dirname, '..')]
} as any);
return this.app.start();
})
afterEach(function () {
if (this.app && this.app.isRunning()) {
// TODO: figure out way to close all windows
return this.app.electron.app.quit();
}
});
it('shows an initial window', function () {
return this.app.client.getWindowCount().then(function (count: any) {
//assert.equal(count, 1)
// Please note that getWindowCount() will return 2 if `dev tools` are opened.
assert.equal(count, 2);
});
});
});

一个简单的解决方案是禁用devtools,因为它们无论如何都不会在您的最终版本中。您可以添加“ --debug”参数(在main.js中进行了解析),并将其添加到package.json中的“ start”脚本中。然后,如果不添加参数,devtools将不会在测试中打开。
如果您想保留devtools或只是要确保退出应用程序,可以使用有点残酷的Node.js exit()
函数来停止主进程:
afterEach(function () {
if (this.app && this.app.isRunning()) {
this.app.mainProcess.exit(0);
}
});
我选择混合使用两种禁用devtools的工具,并确保退出(以防止我的应用程序中任何可能阻止退出的错误)。我不熟悉Mocha,因为我改用AVA,而是用JS而不是TS工作。因此,我尝试修改此代码,但可能会出现一些错误:
beforeEach(function () {
this.app = new Application({
path: electronPath,
// you could add --debug in the following array
// don't do it, to keep the devtools closed
args: [path.join(__dirname, '..')]
} as any);
return this.app.start();
})
// use ES8 'async' to be able to wait
afterEach(async function () {
if (this.app && this.app.isRunning()) {
// get the main process PID
let pid = this.app.mainProcess.pid;
// close the renderer window using its own js context
// to get closer to the user action of closing the app
// you could also use .stop() here
await this.app.client.execute(() => {
window.close();
});
// here, the app should be close
try {
// check if PID is running using '0' signal (throw error if not)
process.kill(pid, 0);
}
catch(e) {
// error catched : the process was not running
// do someting to end the test with success !
return;
}
// no error, process is still running, stop it
this.app.mainProcess.exit(1);
// do someting to end the test with error
return
}
});

试试这个
app.on('window-all-closed', () => {
// prevent quit on MacOS. But also quit if we are in test.
if (process.platform !== 'darwin' || isTest) {
app.quit();
}
});
而 isTest 是 const isTest = process.env.NODE_ENV === 'test';
然后应用程序将正确退出!
要获得 process.env.NODE_ENV
,您可能需要更新您的 webpack 以使用 DefinePlugin:
new webpack.DefinePlugin({
'process.env.NODE_ENV': `"${process.env.NODE_ENV ?? 'production'}"`,
// global: {},
}),
