In this issue, the editor will bring you what is the design principle of the automated testing tool 4399AT. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

Frame foundation

The transformation based on appium is mainly to intercept the auxiliary apk to be installed every time appium runs.

Algorithm basis

The traversal program is improved based on the depth-first traversal algorithm.

Take the home page of the application as the root node, retrieve all the actionable elements on the page, and operate on these elements (such as clicking), resulting in a new page

Record these pages, and then repeat the above with the first page generated by the root node. It is not found on the acquired page.

If an actionable element or encounters a previously visited page, return to the previous page and continue to operate on its neighboring nodes.

Page definition

Page actionable elements are located according to xpath.

The definition of a page is to form an id to identify the page according to the path composition of all the actionable elements in the page.

Therefore, if all the actionable elements in the page are the same, it is considered to be the same page, different means different pages.

The program records the elements that have been manipulated on the page, so if it appears, such as a page clicking a button, the button changes, although it produces

A new page, but will not produce more action elements, nor will it repeat the elements that have been manipulated.

Path recording and redirection

Each step will be recorded, and the operation path from the home page to the current page will be recorded to prevent page changes, or when an exception is returned, the

The element to be manipulated. In this case, the element will be restarted and re-found according to the recorded path.

Re-search the path and optimize the location. If you enter the c page, you need to go through a-> b-> c _ r b at the beginning. It may be a conditional page, or a page that appears only once.

When the path is resought, a cannot reach b, retry a directly to c, and if the arrival is successful, the path will be optimized to a-> c.

Pop window

Divided into installation pop-up window and application pop-up window

Install pop-up window, according to different equipment, use different xpath positioning, automatically click off the installation prompt box to achieve the function of automatic installation.

To apply a pop-up window, you need to deal with the pop-up window path (xpath). Before each operation, you will try to determine whether there is a pop-up window effect.

If it exists, it will point out the pop-up window.

Configuration use case

Api encapsulates appium operations, providing a write mode in json format, which supports embedded manually configured script runs.

The above is the design principle of the automated testing tool 4399AT shared by Xiaobian. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
