What does IDEA think of which version of selenium it uses?

Two methods.

First, open cmd and type python-->import selenium-->selenium.__version__

The second way: open cmd and type pip show selenium pip3 I use here because I have two versions of python installed, so there is a difference.

Based on the text document (markdown), envision the basic required tables, fields, and types;

Use rails migration to create tables as features are developed;

With the development and demand of detailed functions, gradually add fields, delete fields, or adjust field types;

Clean up the migrations and merge them into one at the time of the first release;

As changes are made, fields or tables are added, modified, or deleted.

That's basically how all of my projects work, and it doesn't matter if the project is complex or not.

That's why I said earlier that there needs to be a shift in thinking.

Right-click to check the element before you do it, copy the xpath to record it, or seleniumide to record the script.

This depends on what interface you use, for example, if you are using python, it will be directly:

driver =

Method 1: The most direct way is to look at the difficult files in Python's lib selenium.

Method 2: Create a new empty spring driver object, and then print dir(driver), and other web bucket rulers, all of which can be used in this way, method 3: check the official documentation.

Recommended method three.

It should be, that F capitalization; When the version of Selenium calls Firefox, it seems that you need to use a sock called Lu, **This file can be put in the python27 scripts directory (the premise is that the python27 scripts directory is in the environment variable).

I'm also thinking about this issue at the moment, and there are many factors that influence it.

One of the most common ideas at the moment is to get all the elements on the page that are included"href", you can use the getattribute("href") method, and then make a loop and click in turn.

Of course, the verification is whether there will be a 404 error or something.

However, it has not been put into practice yet, and it feels difficult ......

Add mark to see if there are other gods who have ideas to recommend.
