Write unit tests for most business methods and ensure that the method test passes. 16.6%. Write unit tests occasionally. Generally, do not write them. 58.3%. Write unit
a Introduction to Unit testingUnit testing is the most important tool for code correctness verification, and is the most important part of system testing. is also the only test method that requires code to be written for testing. In the standard development process, the Code of the Unit test is of equal importance to the code of the actual program. Each unit tes
In the previousArticleUnit test training series: (1) unit test concepts and necessity as mentioned in the last section, unit test is fully prepared for testing first and test-driven, I also briefly explained the implementation process. Many of my friends are very interested in this and hope to learn more about how to implement it.

Once a business occurs after a material is created in SAP, it is difficult to modify its basic measurement unit. Because the Organization cannot meet business requirements, it is often required to create a new material to replace the old one. In this case, in addition to deleting all the outstanding services on the old materials, you also need to replace the old materials in the process and BOM. In particular, when old materials exist in multiple Bom,
Recently, I started to learn about unit testing, mainly by learning PHPUnit. At present, I only followed the PHPunit manual and an entry-level tutorial to get started with PHPUnit and practice. I just had a simple understanding and did not have any in-depth research.

Unit Test Tool JUnit 4This article mainly describes how to use the various features provided by JUnit 4 to carry out effective unit testing, and an example of how to use ANT to perform automated unit testing. This article assumes that the reader has some experience with Java development under Eclipse and understands the annotations (annotation) feature in Java 5.
Although there are already a large number of software development methodologies and auxiliary tools to help the development team improve the software quality, prevent and detect bugs, some very simple and practical means are still necessary to improve the software quality, for example, unit test, such as code review.
Unit testing is a basic software quality assurance method. With the popularity of agile d

Warehousing is the primary database operation of the class. ABP opens a database connection and enables a transaction when entering the warehousing method. Therefore, you can safely use the connection to the warehousing method. After the warehousing method is finished, the transaction is committed and the connection is released. If

IntroductionNeedless to tell, programmers are responsible for the code they write, and not only do you have to make sure that it works properly by compiling, but also to meet the needs and design expectations. Unit testing is one of the effective means of verifying that code behavior meets expectations. But there is no denying that testing is a dull and boring thing, and that testing over and over again is a daunting task. Fortunately, the

Unit testing has become an important part of modern software development methods. Even if you disagree with the benefits of extreme programming (XP) or other agile methods, unit testing should be a basic practice in your software development lifecycle.In terms of concept, the persistence layer can be divided into three layers, and ibatis makes
I have been writing unit tests in the company for more than two months (I have had a hard time thinking). To tell the truth, it is a bit like catching up with a duck and doing it at the end of the project, obviously, its role has already been a real name, and I am still looking for new users like me to write (I was not very familiar with the business process at the beginning), so I have been trying to learn Unit
