编辑：感谢mykbas's answer，我启动并运行了我的系统！我为任何想要一步一步的Mac用户编写了一个pretty thorough how-to，包括使用Docker容器的选项:)
我看了看，我在任何地方找不到这个确切的问题，所以我要继续问...我对编程很新，所以我不确定哪些信息很明显/多余的，什么信息至关重要。我会试着在太多方面犯错。
我的最终目标是能够在我的Mac上为使用javascript的网站编写和运行Behat测试。如果我完全走错了路，请随时向我发送另一个方向。
我正在尝试遵循BDD, Behat, Mink and other Wonderful Things教程。直到我们达到涉及Selenium的部分才顺利。
我正在运行Mac OS 10.12.6
我使用composer来安装Behat和一些扩展，
composer require behat/mink-extension behat/mink-goutte-driver
behat/mink-selenium2-driver facebook/webdriver
（当我打字时，我意识到我的问题的一部分可能是我正在尝试使用Selenium 2驱动程序来驱动Selenium 3 ... minkphp/MinkSelenium2Driver: Selenium 3 support #254呃。我应该下载最新版本的Selenium 2吗？除非我读到有关Selenium 2不支持最新版本浏览器的内容，因为它们都会自动更新到我计算机上的最新版本，这将是一个无聊的事情......）
我下载了Selenium Standalone Server 3.8.1并将其粘贴在〜/ Applications中。它不在我的$ PATH中，但由于我直接调用它，我认为它不需要。
我还下载了chromedriver和geckodriver并将它们放在/ usr / local / bin /中，这是我的$ PATH。
$ ./behat --version
behat version 3.4.3
$ chromedriver --version
ChromeDriver 2.34.522932 (4140ab217e1ca1bec0c4b4d1b148f3361eb3a03e)
$ geckodriver --version
geckodriver 0.19.1
（此时我只是谷歌搜索和下载任何听起来适用的东西，希望有些东西有效......：叹气:)
对于浏览器版本，我有：
如果Behat可以成功地与上述任何一个人交谈，我会很高兴。
我的behat.yml包含：
default:
extensions:
Behat\MinkExtension:
base_url: http://127.0.0.1:8000/
goutte: ~
selenium2:
wd_host: 127.0.0.1:4444/wd/hub
我的FeatureContext.php包含：
<?php
use Behat\Behat\Context\Context;
use Behat\Behat\Context\SnippetAcceptingContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;
use Behat\MinkExtension\Context\MinkContext;
/**
* Defines application features from the specific context.
*/
class FeatureContext extends MinkContext implements Context, SnippetAcceptingContext
{
/**
* Initializes context.
*
* Every scenario gets its own context instance.
* You can also pass arbitrary arguments to the
* context constructor through behat.yml.
*/
public function __construct()
{
}
}
我的/features/search.feature包含：
Feature: Search
In order to find products dinosaurs love
As a web user
I need to be able to search for products
@javascript
Scenario: Searching for a product that exists
Given I am on "/"
When I fill in "searchTerm" with "Samsung"
And I press "search_submit"
Then I should see "Samsung Galaxy"
在我的浏览器的单独选项卡中，我启动了Selenium Standalone Server：

“Selenium Server启动并运行”位肯定听起来很有前途！在我的浏览器中访问http://127.0.0.1:4444/和http://0.0.0.0:4444/会带我到一个不错的Selenium Standalone v.3.8.1页面（仅当Selenium在我的终端中运行时才可用），所以Selenium jar文件似乎正在做某事......
当我删除@javascript并运行我的测试（使用Goutte）时，我得到：
$ ./behat
Feature: Search
In order to find products dinosaurs love
As a web user
I need to be able to search for products
Scenario: Searching for a product that exists # features/search.feature:7
Given I am on "/" # FeatureContext::visit()
When I fill in "searchTerm" with "Samsung" # FeatureContext::fillField()
And I press "search_submit" # FeatureContext::pressButton()
Then I should see "Samsung Galaxy" # FeatureContext::assertPageContainsText()
1 scenario (1 passed)
4 steps (4 passed)
0m3.15s (14.27Mb)
然而，当我把@javascript放回去（所以它使用Selenium）时，Firefox会启动，然后只是坐在那里。大约45秒后，我的终端感到无聊并吐出以下内容：
./behat --verbose

如果你们有任何经验让Behat与Mac上的浏览器交谈，我真的非常感谢你的帮助。如果你需要更多的信息（比如日志或其他东西），我会完全提供它，但你可能需要给我“白痴指南”如何找到它...
无论如何，感谢所有这一切，并提前感谢您提供的任何帮助:)
遇到了同样的问题，有一个known issue with new mink-extension 2.3所有你需要的只是设置marionette: null
extensions:
Behat\MinkExtension:
base_url: http://127.0.0.1:8000
javascript_session: selenium2
browser_name: chrome
selenium2:
capabilities:
# required by mink-extension 2.3
marionette: null
browserName: chrome
browser: chrome
version: 63
您需要在启动selenium服务器时设置驱动程序。
java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar path_to_selenium_server.jar
我建议将它们（selenium服务器和浏览器驱动程序）放在同一目录中，并使用bash脚本启动服务器。
如果本地计算机上的服务器具有默认端口wd_host，则不必指定4444。
我没有尝试使用firefox，chrome效果很好。你什么时候使用浏览器，你应该让@javascript标记在功能级别，你也可以使用@insulated，这样你的浏览器就可以开始干净，没有cookie和缓存。
@insulated @javascript
Feature: Feature name
@my_tag
Scenario: Feature name - scenario summary尝试一下behat.yml：
default:
suites:
default:
contexts:
- FeatureContext
formatters:
pretty:
junit:
html:
output_path: %paths.base%/report
extensions:
Behat\MinkExtension:
goutte: ~
selenium2:
browser: chrome
capabilities:
chrome:
switches:
- "start-maximized"
base_url: 'base_url'
dev:
extensions:
Behat\MinkExtension:
base_url: 'base_url_dev'
当您使用其他浏览器时，您还应该使用该驱动程序启动selenium服务器，并在behat.yml中更改名称，对于firefox，您需要geckdriver并使用gecko.driver而不是chrome。
另一种解决方案可能是跳过硒并直接通过D.More的ChromeExtension使用镀铬驱动程序。使用Chrome驱动程序可在窗口和无头工作。使用无头版本的铬和这个驱动程序也比使用硒快很多。供参考我的behat.yml：
default:
translation:
locale: nl
extensions:
DMore\ChromeExtension\Behat\ServiceContainer\ChromeExtension: ~
Behat\MinkExtension:
browser_name: chrome
base_url: https://www.yoursite.com
sessions:
default:
chrome:
api_url: "http://127.0.0.1:9222"
download_behavior: allow
download_path: ~/Downloads
validate_certificate: false
还有我的composer.json：
{
"require-dev": {
"behat/behat": "^3.4",
"behat/mink-extension": "^2.3",
"behat/mink-selenium2-driver": "^1.3"
},
"require": {
"behat/mink-goutte-driver": "^1.2",
"dmore/chrome-mink-driver": "^2.5",
"dmore/behat-chrome-extension": "^1.1"
}
}
请注意，您需要在运行behat之前启动chrome（无头或无头）。为此，我在.bash_profile中创建了三个别名（在我的家里 - dir中：
alias chrome='/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome'
alias chromedriver='chrome --disable-gpu --remote-debugging-address=127.0.0.1 --remote-debugging-port=9222'
alias chromedriverheadless='chrome --disable-gpu --headless --remote-debugging-address=127.0.0.1 --remote-debugging-port=9222'
chromedriver（检查你位于$ PATH某处的位置）应该与安装的Chrome版本相匹配。如果它停止工作，Chrome通常会自行更新，但不会更新chromedriver。我有这个解决方案在我的Mac上工作。
