Question

我用量角器进行e2e测试。当我的应用程序在服务器上运行时，测试通过正常，然后浏览器关闭，但是当服务器关闭时，浏览器仍然存在（Firefox，Chrome）。在我的本地机器上可以，但我正在尝试在远程CI机器上运行测试，并担心如果服务器无法运行，测试可能会产生多个浏览器窗口。如何确保量角器在这种情况下关闭浏览器窗口？

这是我的配置：

exports.config = {
    allScriptsTimeout: 11000,
    specs: [
            '../test/e2e/*.js'
    ],
    capabilities: {
        'browserName': 'firefox'
    },
    baseUrl: 'http://localhost:8000/',
    framework: 'jasmine',
    jasmineNodeOpts: {
        defaultTimeoutInterval: 30000
    }
};

，测试是：

'use strict';

describe('typicaClient', function() {
    browser.get('index.html');

    it('test', function() {
        expect('str').toMatch('str');
    });
});

量角器让浏览器在那些无法识别且无法处理的错误上打开。

查看以下示例。由spawn()进程抛出的此错误未被Protractor处理，并以错误代码退出 - 199

describe('sample test', function(){
    it('Sample Check', function(){
        browser.get("http://www.protractortest.org/#/");
        browser.sleep(5000);
        var terminal = require('child_process').spawn('34e3545')
    });
});

输出：

[18:26:46] I/local - Starting selenium standalone server...
[18:26:46] I/launcher - Running 1 instances of WebDriver
[18:26:46] I/local - Selenium standalone server started at http://192.168.1.5:61146/wd/hub

    at process._tickCallback (node.js:356:17)
[18:26:49] E/launcher - Process exited with error code 199

要避免这些，请在非量角器命令中正确处理错误

describe('sample test', function(){
    it('Sample Check', function(){
        browser.get("http://www.protractortest.org/#/");
        browser.sleep(5000);
        var terminal = require('child_process').spawn('34e3545').on('error', function(err) {
            fail('Test is failing because we provided an invalid process')
        });
    });
});

在这种情况下输出：

[18:57:22] I/local - Starting selenium standalone server...
[18:57:22] I/launcher - Running 1 instances of WebDriver
[18:57:22] I/local - Selenium standalone server started at http://192.168.1.5:49867/wd/hub

查看此情况处理未处理的异常并且Protractor抛出错误代码 - 1正常处理

当服务器不可用时，量角器不会关闭浏览器
