Because of some confusion, so prepare to direct the project

Start learning a python web-driven test without thinking that it was wrong in the first place.

Environment is the latest version of Python,selenium,firefox,django, etc.

Tap the code on the book

From selenium import webdriver
browser = webdriver. Firefox ()
browser.get (' http://localhost:8000 ')
assert ' Django ' in Browser.title

Results no information wrong

The key part is probably to say my what geckodriver all sorts of wrong

No paths were found and no path was added or anything

Baidu has found that a lot of people have this problem

Understand a bit about

Geckodriver is a Firefox driver.
But most of the online solutions are win.

StackOverflow a foreigner gave a solution to the downgrade, but the demotion is not always a good way, so continue to find

In general, the solution is to install Geckodriver on your own and add to the relevant path

So to GitHub (poke here) Download the Linux Geckodriver

Then do the related actions

sudo tar zxvf geckodriver-v0.11.1-linux64.tar.gz #解压

sudo mv geckodriver/usr/bin/#移动到指定路径

cd/usr/bin/                    #进入路径

sudo chmod +x geckodriver        #除去权限

After testing the Python code again, the success

A little cool, hey.

The solution comes from http://blog.csdn.net/heybob/article/details/52922645

Thank you, great God.
