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
The purpose of this blog is to be seen in the title. This is also our experimental needs, we must summarize, to facilitate the other younger sister on this basis to do experiments.I've introduced a lot of kieker-based monitoring methods, and here's an example of Prefuse, an open-source visual Java framework, that summarizes how junit and ant enable monitoring of the open source software's own test case exec

Use Maven to create a WebApp project online a lot of information, not in detail here. After the completion of the creation, it is said to switch to the Dynamic Web project to change to 3.0 version, but I do not locally switch, the online method seems useless, and temporarily useless to this piece. After the SSM framework is set up, let's elaborate on this piece. Today's talk is about the pit for the JUnit unit tes

Eclipse originally provides the running and debugging functions of JUnit. However, in large-scale project development, ant is often used to maintain the compilation, packaging, and testing of the entire code. However, Environment configuration is often performed before testing. These configurations are often completed by ant, so the test entry starts from running ant, however, it is difficult to debug a
JUnit testing SSH JUnit can be used to test Java Web applications that use the SSH open-source framework. The DAO method and service-layer business logic method can be easily tested without relying on the framework.
To test the methods in Dao and service, you must first obtain the class instance. I think this is the
