During handling of the above exception, another exception occurred:

  File "seleniumtest.py", line 4, in <module>
    driver = webdriver.Chrome(executable_path='')

    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: '' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

解決策

1. PATH直打ち

driver = webdriver.Chrome(executable_path='/c/******/******/chromedriver.exe')

バックスラであることに注意。

2. chromedriverの更新

下記を参照し使っているChromeのバージョンにあったchromedriverに更新する。
