NoSuchWindowError:浏览上下文已被GeckoDriver Firefox和Protractor(Selenium)丢弃

问题描述

限时删除！！

我正在尝试使用量角器运行一个简单的测试脚本.

I'm trying to run a simple test script using protractor.

环境:

Node Version: v9.8.0
Protractor Version: 5.4.1
Angular Version: 1.x
Browser(s): Mozilla Firefox 60.1.0
Operating System and Version: HELiOS release 6.10

这是我的量角器配置文件.

Here's my protractor config file.

exports.config = {
  specs: ['todo-spec.js'],
  capabilities: {
    browserName: 'firefox',
    marionette : true
  }
};

这是我的测试脚本(todo-spec.js)

This is my test script (todo-spec.js)

describe('application homepage', function() {
  it('should open homepage', function() {
    console.log("Opening localhost app");
    browser.get('http://localhost:8080/app/');
    browser.sleep(20000); // just to check if application loaded or not
  });
});

这是我的 node_modules/protractor/node_modules/webdriver-manager/selenium/目录，如下所示:

This is my node_modules/protractor/node_modules/webdriver-manager/selenium/ directory looks like:

使用/path/to/protractor conf.js运行测试时，出现以下错误.

When I run my test using /path/to/protractor conf.js, I'm getting below mentioned error.

Any help would be appreciated.

推荐答案

可以通过以下配置解决此问题.

Was able to fix this issue with below configuration.

- Protractor: v5.4.1
- Selenium JAR driver: selenium-server-standalone-3.141.59.jar
- geckodriver:geckodriver-v0.20.0-linux64

我们还需要在量角器conf文件中提供geckodrvier的路径.

Also we need to give path of geckodrvier in protractor conf file.

geckoDriver: 'node_modules/protractor/node_modules/webdriver-manager/selenium/geckodriver-v0.20.0'

默认情况下，webdriver-manager将下载最新版本的geckodriver，该版本为0.24.0.但是所需的geckdriver是v0.20.0，因此我手动下载了它，并将其放在node_modules/protractor/node_modules/webdriver-manager/selenium/目录中.

By default webdriver-manager will download latest version of geckodriver which is 0.24.0. But the needed geckdriver is v0.20.0, so I downloaded this manually and placed it inside node_modules/protractor/node_modules/webdriver-manager/selenium/ directory.

希望这对面临类似问题的人们有所帮助.
