Use the combination of Java, Selenium and OpenCV to solve the problem of slider verification in automated testing.

1. Slider verification idea The slider object of the object under test looks like this. Relatively speaking, it is a relatively simple form. You need to drag the puzzle on the left through the slider below and embed it into the empty slot on the right to complete the verification. To automate this verification process, the key point is to determine the distance the slider slides. According to the above analysis, the key point of verification is to determine the sliding distance of the slider. But a seemingly simple requirement is not simple to complete. If you use natural logic to analyze this process, it can be broken down as follows: 1. Locate the position of the puzzle on the left. Since the shape and size of the puzzle are fixed, you only need to locate the distance between its left border and the left side of the background image. (Actually, in this example, the starting position of the puzzle is also fixed, saving

What are the ORM frameworks in Java?

1. Hiberante object-oriented ORM has a relatively high learning cost. 2. Mybatis semi-automatic ORM framework requires you to write sql yourself, which facilitates the separation of sql and java code. The so-called "semi-automatic" here is relative to the full table mapping of the Hibernate framework. The MyBatis framework needs to manually match and provide POJO, SQL and mapping relationships, while the Hibernate framework only needs to provide POJO and mapping relationships. 3.Bee is a new ORM framework that combines the advantages of Hiberante and Mybatis. You can operate the database through operating objects like Hibernate, or you can write sql4 flexibly like Mybatis.

Reflection from an old foreign programmer: You can't have C, Python, and Java at the same time, just concentrate on learning one programming language well!

Recently, John Carmack, a famous game programmer and co-founder of idSoftware, said in an interview that programmers should concentrate on learning a programming language well. This surprised me a bit. While I personally strongly agree with this advice, this view is controversial in today's programmer circles. I guess I'm what everyone calls an "old programmer". I am not young, I have been engaged in programming all my life, and I have been engaged in this professional work since I entered the society. Sometimes I feel like a programming language enthusiast who has witnessed the development of many programming languages. Looking back at the past, this is an exciting history, and we can't help but come to the (wrong) conclusion that it is not bad to know a few more programming languages.
