I don't know if you have read these two books: pragmatic unit testing -- in Java with JUnit and pragmatic unit testing -- in C # With nunit. The content is very good. For example, let's inspire you to test this aspect and put forward a few days of pragmatic suggestions:

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:
Create a Java project in eclipse.

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

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
First, the benefits of using spring test suites
When developing a spring-based application, if you also use JUnit directly for unit testing, you're missing out on the huge feast that spring offers us. Using JUnit for unit testing directly has the following four drawbacks:
1 causes multiple spring container initialization issues
Each execution of a test method creates an instance of a test case and invokes t
1. To simplify JUnit testing, the spring framework can also be used to integrate testing2. Specific stepsRequirement: There must be a junit environment first (that is, a development environment that has been imported into the JUNIT4)Step one: Introduce Spring-test.jar in the programStep Two: Add annotations on the specific test class

1. parameterized Test
Sometimes, different parameter values in a test method produce different results. To test the completeness of the test, multiple parameter values are written and tested one by one, in this way, it is sometimes time-consuming and labor-consuming, so we can use parameterized tests to solve this problem. Parameterization testing is like passing in a set of "input value, expected value" to the test method to achieve one-time testing.

This article describes how to use JUnit for the first time.
