带有Chromedriver的Nightwatch在断言后不会退出

Question

我有一个问题，在所有断言过去后，守夜人没有退出。尽管关闭了 chrome 驱动程序，但执行似乎冻结并且永远不会退出。

版本如下：

chromedriver (headless): 2.41.0
selenium-server: 3.14.0
nightwatch: 1.0.9

火狐驱动程序工作正常。

运行器.js的内容如下：

// 1. start the dev server using production config
process.env.NODE_ENV = 'testing';
const webpack = require('webpack');
const DevServer = require('webpack-dev-server');
const webpackConfig = require('../../build/webpack.prod.conf');
const devConfigPromise = require('../../build/webpack.dev.conf');
let server;
devConfigPromise.then((devConfig) => {
const devServerOptions = devConfig.devServer;
const compiler = webpack(webpackConfig);
server = new DevServer(compiler, devServerOptions);
const port = devServerOptions.port;
const host = devServerOptions.host;
return server.listen(port, host);
})
.then(() => {
// 2. run the nightwatch test suite against it
// to run in additional browsers:
//    1. add an entry in test/e2e/nightwatch.conf.js under "test_settings"
//    2. add it to the --env flag below
// or override the environment flag, for example: `npm run e2e -- --env chrome,firefox`
// For more information on Nightwatch's config file, see
// http://nightwatchjs.org/guide#settings-file
let opts = process.argv.slice(2);
if (opts.indexOf('--config') === -1) {
opts = opts.concat(['--config', 'test/e2e/nightwatch.conf.js']);
}
if (opts.indexOf('--env') === -1) {
opts = opts.concat(['--env', 'chrome']);
}
const spawn = require('cross-spawn');
const runner = spawn('./node_modules/.bin/nightwatch', opts, { stdio: 'inherit' });
runner.on('exit', (code) => {
server.close();
process.exit(code);
});
runner.on('error', (err) => {
console.log(`About to exit with code: ${err}`);
server.close();
throw err;
});
});

Nightwatch.conf.js的内容如下：

require('babel-register');
const config = require('../../config');
// http://nightwatchjs.org/gettingstarted#settings-file
module.exports = {
src_folders: ['test/e2e/specs'],
output_folder: 'test/e2e/reports',
custom_assertions_path: ['test/e2e/custom-assertions'],
selenium: {
start_process: true,
server_path: require('selenium-server').path,
host: '127.0.0.1',
port: 4444,
cli_args: {
'webdrive.gecko.driver': require('geckodriver').path,
'webdriver.chrome.driver': require('chromedriver').path,
},
},
test_settings: {
default: {
selenium_port: 5555,
selenium_host: 'localhost',
silent: true,
globals: {
devServerURL: `http://localhost:${process.env.PORT || config.dev.port}`,
serverUrl: '[server url]',
},
},
chrome: {
desiredCapabilities: {
browserName: 'chrome',
javascriptEnabled: true,
acceptSslCerts: true,
chromeOptions: {
args: [
'--headless', '--no-sandbox',
],
},
},
},
firefox: {
desiredCapabilities: {
browserName: 'firefox',
javascriptEnabled: true,
acceptSslCerts: true,
'moz:firefoxOptions': {
args: [
'-headless',
],
},
},
},
},
};

任何帮助将不胜感激，因为到目前为止我还没有找到解决方案。

首先，确保将 browser.end(( 作为每个测试的最后一步。

其次，Nightwatch 1.0+仍处于测试阶段。我会尝试版本 0.9.21，这是大多数人仍在使用的。如果 0.9.21 有效，则针对 1.09 版提交错误。
