Springboot java introduces Mqtt to receive and send messages under the framework of the front and back separation version

This is just one of them, and it is a superficial method of receiving and sending messages. The synchronization mechanism needs to be communicated and confirmed with colleagues engaged in the Internet of Things to see if it can be implemented. Or if there are many devices, the synchronization mechanism will not be used. First, […]

UI automation test framework design and PageObject transformation!

During the UI automation testing process, faced with complex business scenarios, we often encounter the following challenges: Simple recording/playback is fast, but cannot adapt to complex scenes; Writing automated test scripts is more flexible, but the workload is heavy and maintainability is poor; The previous encapsulation technology (PageObject) can adapt to various UI scenarios, but […]

Implementation of interface automation testing framework based on Junit!

Layered automated testing 5 to 10 years ago, the automated testing we came into contact with was more focused on automated testing of the UI layer. Mercury’s WinRunner/QTP was a typical representative of the commercial automated testing products of that era. At that time, everyone simply wanted to use a Automated tools replace human clicks, […]

No framework, just use numpy to write a wonderful chapter of DNN (Deep Neural Networks)

1. Overview A Logistics Regression can be thought of as a simple neural network consisting of only one hidden layer (Hidden Layer) (as shown in the figure below). However, Logistic Regression is often very sensitive to outliers, and it is difficult to deal with polyphenols. Therefore, people were inspired by human brain nerves and established […]

WinForm application interface development practice – how to integrate external API interface calls in a hybrid framework

In our regular business processing, most of the internal processing interfaces are database-related and based on the Winform development framework of hybrid development. Although when the client calls, the general choice is also based on Web API calls, but the back-end We may not only process our business database, but also call other external interfaces, […]

Byte’s 10 years of experience – developing an automated testing framework from 0 to 1!

1. Preface With the rapid iteration of project versions, APP testing has the following characteristics: First of all, there are many and detailed function points, the testing workload is large, and it is easy to miss; Secondly, code modules are often changed, regression testing is frequent, and testing is repeated and inefficient; Finally, the data […]
