unit testing, you miss the most important hard dish in spring feast.Before we go into this dish, let's talk about the problem of using JUnit directly for unit testing in a spring-based Javaweb project.1) causes multiple spring container initialization problemsDepending on the invocation process of the JUnit test metho

(Suite. Class)@Suite. suiteclasses ({Calculatortest. Class,Squaretest.

At the same time, we need another callout @suite.suiteclasses to show that this class is a packaged test class. We pass the class that needs to be packaged as a parameter to the callout. With these two annotat

Exceptions that are actually thrown2. Class type that throws an exception3. Throw out the specific type of exception, general check the exception of the message attribute of the string contained in the determ

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
