Introduction to JUnit
JUnit is an open source unit testing framework for writing and running automated tests, developed by Erich Gamma and Kent Beck in 1997. It includes the following features:
The API provided allows you to write out a reusable unit test case with a clear test result;
Provides three ways to display your test results, and can also be extended;
The function of unit test cases running in
To establish a project:

With the principle that "programmers who don't write unit tests are not good programmers," I'm sticking to the unit test, not saying that all Java Web Apps are based on spring, but at least more than half are based on spring. It is found that after bean management through spring, there are a variety of deficiencies in testing,
For example, when a lot of people do unit tests, they also initialize the spring container in the Before method, causing the container to be initialized multiple times.

Recently, Spring-test+junit unit tests were done with Spring2.5.6 and JUnit4.7 but the following exceptions occur: Org.apache.maven.surefire.booter.surefireexecutionexception:org/junit/assume$assumptionviolatedexception; Nested exception is java.lang.noclassdeffounderror:org/junit/assume$assumptionviolatedexception Looks like it's missing org.junit.assume$assumpt
Running multiple classes
JAVA-CP [Your test jar and Junit.jar] Org.junit.runner.JUnitCore [Your test class, can be multiple]
Example: JAVA-CP test.jar;junit-4.1.1.jar org.junit.runner.JUnitCore test. Simple1 test. Simple2 test. Simple3
Run a single class
JAVA-CP [Your test jar and Junit.jar] junit.textui.testrunner-c [Your test class, without the-c parameter]
Example: JAVA-CP test.jar;junit-4.1.1.jar
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

It can be seen from the table that JUnit is a well-established unit test tool in terms of support for relevant documents (forums, contact l
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 most important thing. In SSH, Dao and service are both managed through spring, so they ca
Java annotation (annotation) is used by @ annotation name, which can be implemented by simple words. Commonly used annotations in JUnit include @ test, @ ignore, @ beforeclass, @ afterclass, @ before, @ After, @ runwith, and @ parameters. The following are related introductions and instructions: 1. [email protected] In junit3, the test class and test method are named to determine whether it is a test, and all test classes must inherit the test base cl
Why use JUnit, what kind of tool is it?JUnit is a unit test tool.To put it bluntly, JUnit allows us to execute a method without the main method.Requirements for the method being tested:1. The method being tested cannot have parameters and cannot have a return value.2. To use JUnit, you need to import JUnit's jar packag

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 test that was encountered when building t

Reference article: Spring MVC full Annotation configuration-no web. xmlThe purpose of unit testing, in short, is to test all logic after we add or change some code, especially after we have modified it later (whether adding new features or modifying bugs), we can do the work of re-testing. To reduce the problem that we have solved even before the release of the issue.Spring MVC testing often seems more complex. In fact his difference is that he needs a servletcontext to simulate our request and
