selenium-webdriver - Behat + mink + Selenium2 + chromeDriver : Do not launch chrome browser

Question

我使用的是 ubuntu 14.4。

当我运行测试时，它在 firefox 上运行良好，它会启动 FF 浏览器。

但是，当我对 Chrome 进行同样的尝试时，测试会运行，但不会启动浏览器。

Composer .json

{
    "require": {
    "behat/behat": "2.4.*@stable",
    "behat/mink": "1.5.*@stable",
    "behat/mink-goutte-driver": "*",
    "behat/mink-extension": "*",
    "behat/mink-selenium2-driver": "*"
    }
}

behat.yml

default:
 paths:
  features: features
  bootstrap: %behat.paths.features%/bootstrap
 extensions:
  Behat\MinkExtension\Extension:
    base_url:  'path-to-my-site'
    default_session: selenium2
    browser_name: 'chrome'
    goutte: ~
    selenium2:
        wd_host: "http://127.0.0.1:4444/wd/hub"

启动Selenium Server的命令

java -jar /path-to/selenium-server-standalone-2.47.1.jar -Dwebdriver.chrome.driver="/usr/local/share/chromedriver"

这是我上面命令的输出:

Behat测试命令:

vendor/bin/behat

行为测试的输出

Feature: Home page
    I am on a home page

  Scenario: Visit homepage                       # features/test.feature:4
    Given I go to "home.html"                    # FeatureContext::visit()
    Then I should see "We can change the world!" # FeatureContext::assertPageContainsText()
    Then I follow "Register"                     # FeatureContext::clickLink()

1 scenario (1 passed)
3 steps (3 passed)

问题是 Test Works 但 chrome 浏览器没有启动。我做错了什么？

Answer 1

您应该在场景之前添加 @javascript 标签，因为默认情况下 behat 使用的是 goutte session ，而不是使用 selenium webdriver。更多关于 Goutte driver

@javascript
Scenario: Visit homepage

或者在behat.yml中设置默认session为selenium2

extensions:
    Behat\MinkExtension\Extension:
      default_session: selenium2

但在那之后 behat 将启动 firefox 浏览器，特别是启动 chrome - 你应该添加 browser_name: chrome 选项

extensions:
    Behat\MinkExtension\Extension:
      browser_name: chrome

你还应该为 selenium2 配置参数指定 wd_host 参数

extensions:
    Behat\MinkExtension\Extension:
      selenium2:
            wd_host: "http://127.0.0.1:4444/wd/hub"
