Interface Automation uses reflection to solve the problem of data dependencies

First, let's look at what is reflected in python?

The method of reflecting it can map to a string or instance variables instance may then be performed to load, modify, and other operations. It has four important ways:

• getattr Gets the object attribute specifies the name of the string
• set a target object setattr
• Determining whether the object has hasattr corresponding object (String)
• delattr delete the specified property

Here I talk about two commonly used.

Figure:

Defines a GetData () class, there is provided a class attribute, cookie = None, and then set a new value function setattr object GetData inside cookie attributes, i.e. COOKIE = biscuits, inside the final value and then removed getattr function. As can be seen, which is the attribute value of the replacement process.

The above talked about the concept of reflection, Here's what practical use, how to use reflection to resolve data dependencies.

Test target, after a successful login, see my boutique interface. Avatar and assert the upper right corner of the student's name. Specific interface as follows:

To see my first boutique interface, you must be logged. FIG login interface code as follows:

GetData introduced first class, then the login is successful, the login is successful after determining if the cookie to use, setattr (GetData, 'cookie', login_res.cookies), to which the cookie = None GetData class attribute setting new properties.

Use the time to use getattr (GetData, 'cookie'), the inside of the extracted attribute value. I figure below boutique transfer cookie login page.

All code is as follows:
