In the "programmers who don't write unit tests are not good programmers" principle, I'm sticking with the unit test, not saying that all Java Web applications are based on spring, but at least more than half are spring-based. After discovering bean management through spring, there are a variety of deficiencies in testingFor example, when many people do unit tests, they also initialize the spring container in the Before method, causing the container to
In the development of projects, it is unavoidable to use unit testing. Let's start with some basic concepts. 1) @Test @ is the meaning of the annotation, @Test is the basis of the JUnit test, which means that the method under the note is run with JUnit testing. 2) Import p
First , advanced Fixture In the previous article we introduced two Fixture annotations, namely @Before and @After, to see if they are suitable for the following functions: one class is responsible for reading and writing large files (more than 500 megabytes), and each of his methods is manipulating the files. In other words, before invoking each method, we have to open a large file and read the contents of the file, which is definitely a time-consuming operation. If we use @Before and @After,
Android SDK 1.5 has been included in JUnit, used once, last night re-use when there is a bit of a problem, or decided to write a more detailed article for everyone and their future use, writing is also very convenient, JUnit under Android is an extension to JUnit under Java, which is basically similar toabout JUnitJUnit is an open-source Java Unit Testing framewo
After two days of web development and discovering object management through spring, testing became complicated. Because all the beans need to be loaded in the Applicationcontext.xml, and then through the @resource to obtain. It is inefficient and cumbersome to test the entire business flow every time it is done. It's too tedious to write a test class alone. So I think spring has a
test, and then test it. But it's a hassle to write test cases every time you need to create a new class.Having said so much, the welfare came. Unit Test Tool--junit. Assist us with unit testing and provide many conveniences. Here's how to use

In the evening, I briefly talked with Xiao Bing about the method of using JUnit to test the filenet PE class. The advantage of using JUnit for testing is self-evident when using the main () method in the class. Although the necessity and superiority of lab and JUnit are not significant, it is worth exploring.
As a know
Today we talk about JUnit testing techniques, which most people have heard, it's just that some people don't use it, it's easy to say, but it's really an essential technology in the software development process, for some irregular small companies maybe the product release is not tested, but for large software development, This technology is often essential, because any error in a small place can be difficult to find, but the
What is the difference between testing a parallel program and the past?
With the popularization of multi-core, the development of parallel programs has been put on the agenda. Parallel programs are more likely to go wrong than serial programs. On the one hand, the execution sequence of parallel program has very strong randomness, the sequence of thread staggered execution may be different every time, and as long as a sequence has a problem, the whole program is incorrect. On the other hand, par
November, was sent to a pure backstage project; At the time, I thought Jmock was just a technology for junit testing, and there's nothing too much for our developers to know about. I feel like my buddies don't have to jmock. The same can be done to JUnit, the same can improve coverage; As unit testing progresses, I slowly discover that some methods, if not used Jmock, spend much more time and effort than u
