我正在尝试使webdriver.io和Jasmine工作。

按照他们的示例，我的脚本位于test/specs/first/test2.js（根据配置），其中包含：

var webdriverio = require('webdriverio');


describe('my webdriverio tests', function() {

    var client = {};
    jasmine.DEFAULT_TIMEOUT_INTERVAL = 9999999;

    beforeEach(function() {
        client = webdriverio.remote({ desiredCapabilities: {browserName: 'firefox'} });
        client.init();
    });

    it('test it', function(done) {
        client
            .url("http://localhost:3000/")
            .waitForVisible("h2.btn.btn-primary")
            .click("h2.btn.btn-primary")
            .waitForVisible("h2.btn.btn-primary")
            .call(done);
    });

    afterEach(function(done) {
        client.end(done);
    });
});

我使用wdio作为测试运行程序，并使用交互式设置进行设置。该配置是自动生成的，并且都非常简单明了，因此我认为不需要发布它。

在另一个终端窗口中，我正在使用Java 7运行selenium-server-
andalone-2.47.1.jar。我的计算机上确实安装了Firefox（运行测试时空白启动），并且我的计算机正在运行OS 10.10。 5，

当我启动测试运行程序时，会发生以下情况：

$ wdio wdio.conf.js

我发现这非常奇怪且莫名其妙，尤其是考虑到它甚至可以打印会话ID。

有任何想法吗？
