similarities and differences between JSP and servlet?JSP is the extension of servlet technology, is essentially a simple way of servlet, JSP more emphasis on the application of the appearance of expression, compiled is "class servlet." The main difference between Servlets and JSPs is that the application logic of the servlet is in the Java file and is completely detached from the HTML in the presentation layer, whereas the JSP case is that Java and HTML can be combined into a file with a. jsp e

Why Write unit TestsThe first step is to introduce the practice of unit testing for the financial side of Mushroom Street payment. It's a bit of a coincidence, just at the beginning, I would write unit tests alone. Then the bosses knew and thought it was a valuable thing, so they called me in charge of the unit test for our group. So slowly, unit testing has become a normal

The same is rookie, some people 3-5 years later became the front-end architect, some people 3-5 years later in the endless new framework to the button binding event, want to become what kind of person, will pay what kind of effort, most of the time is no fault. The basics are important! It's important! It's important!3. The basis of this

Greatly affected by front-end style changes More external dependencies, not all use cases can be automated Limited coverage capacity Although we implemented script concurrency and failure use case retry mechanisms to improve execution efficiency and reduce false positives by combining Selenium-grid at the test framework and tool level, this approach only alleviates the problem and does not solve the problem o

(Synchronized from http://www.blogjava.net/AndersLin/archive/2006/06/12/52298.html) Using unit testing in the system development process brings many benefits, most obviously: When you become convinced of the value of comprehensive unit testing, you'll find that it begins to influence how you write code, and the frameworks you choose to use. The first thing to solve in application unit testing isFocus of Unit Testing.The focus of testing is the test l

I went to a game company for an interview two days ago. The interviewer is the head of the operations department. Because the written test is a mess, it is directly despised. The interviewer didn't bother to say anything. In fact, a lot of written questions are basic types, test center also know, but not good summary p
