from selenium import webdriver
browser = webdriver.Firefox()
browser.get(‘http://localhost:8000‘)
assert ‘Django’ in browser.title
結果執行Python程式碼報錯：

解決方法：
到https://github.com/mozilla/geckodriver/releases下載了Linux的geckodriver
然後進行相關操作
**sudo tar zxvf geckodriver-v0.11.1-linux64.tar.gz #解壓
sudo mv geckodriver /usr/bin/ #移動到指定路徑
cd /usr/bin/ #進入路徑
sudo chmod +x geckodriver #除去許可權**

再次執行Python程式碼 成功了能夠自動開啟瀏覽器了
