尝试使用phantomjs和Selenium运行单元测试时出错

标签： javascript unit-testing intern

我尝试按照Wiki页面中列出的步骤解决我的问题，并在与Selenium服务器运行phantomjs时使用github.com/theintern/intern-examples/phantomjs-example。虽然我仍然收到此错误：

$ ./node_modules/.bin/intern-runner config=tests/intern

其他人遇到同样的问题并知道如何解决？

来自Wiki的说明：

  1. 在Intern中使用本地PhantomJS安装非常简单：在Intern配置中，设置environments: [ { browserName: 'phantomjs' } ]和tunnel: 'NullTunnel'
  2. 确保包含phantomjs可执行文件的目录位于PATH中（如果使用npm install -g phantomjs安装，通常就是这种情况）
  3. 启动您当地的Selenium服务器(java -jar selenium-server-standalone-2.xx.x.jar)
  4. 运行intern-runner config=path/to/config

    5. 我使用的所有文件：https://github.com/theintern/intern-examples/tree/master/phantomjs-example

PhantomJS是broken with Selenium 2.44.0 now too。

最佳解决方案：停止使用PhantomJS！
替代解决方案：只要使用PhantomJS补丁，就会使用Selenium 2.43或更早版本。

PhantomJS与Selenium 2.45配合使用
