在CircleCI上運行python硒測試

Question

我想在CircleCI的測試階段運行一些python硒測試。

我circle.yml看起來是這樣的：

machine: 
    python: 
    version: 2.7.9 
    node: 
    version: 0.10.34 
    java: 
    version: oraclejdk8 
dependencies: 
    post: 
    - pip install selenium 
    - wget http://selenium-release.storage.googleapis.com/2.44/selenium-server-standalone-2.44.0.jar 
    - java -jar selenium-server-standalone-2.44.0.jar: 
     background: true 
test: 
    post: 
    - python /home/ubuntu/app/tests/tests.py 
... 

和tests.py看起來是這樣的：

from selenium import webdriver 

driver = webdriver.Chrome() 
driver.get('http://127.0.0.1') 

print driver.find_element_by_class_name('a-class').text 

我有兩個問題：

首先，如何I輸出數據從test.py返回到CircleCI的界面（打印語句顯然不起作用）

其次，在撥打電話driver.get()時使用的正確地址是什麼，因爲我收到http://127.0.0.1/ is not available錯誤？

以下是完整回溯：

http://127.0.0.1/ is not available 
Traceback (most recent call last):

終於想通了。從http://docs.seleniumhq.org/docs/04_webdriver_advanced.jsp#remotewebdriver

driver.get('http://localhost:4444/wd/hub') 

將其設置是否正確和標準的打印報表做的工作，以輸出結果反饋給CircleCI。
