Junit
1. What is Junit?
It is an open-source Java testing framework for compiling and running repeated tests. Is an example of the unit test framework system XUnit. Junit is used in Java. (In addition, Cunit and so on)

The Junit tool is used for unit testing and is an essential tool in extreme programming. Tools that must be mastered by Java developers.First, risks are everywhere in the process of software development. Fundamentally, we cannot eliminate these risks, but we can test to reduce the risks and improve the reliability of development, and the final software quality.
So what is the responsibility of the test we are talking about? The mos
Introduction to the Junit test frameworkThe test framework is the most popular Java unit testing framework. JUnit is used to develop unit tests on Java classes. It is a class package that provides a variety of ways to test methods in a Java class. Junit 4 Features
Simple annotations that provide the basic features of writing
for developers to perform unit tests, especially if JUnit 4 uses annotations in Java 5 (annotation) to make testing easier.JUnit 4 First ExperienceBefore we begin to experience JUnit 4, we need support for the following software:
Eclipse: The most popular IDE, which fully integrates JUnit and supports JUnit 4

1. Several Related Concepts
White-box test-the test object is regarded as an open box. The logic structure and other information in the program are made public to the tester.
Regression testing-software or environment repair or corrected "retest", which is especially useful for such testing.

will show a simple junit example. First look at the classes we want to test:Calculate.java:package com.javacodegeeks.junit;publicclass Calculate { publicintsum(intint var2) { System.out.println("Adding values: "" + " + var2); return var1 + var2; }}In the above source code, we see that the class has a public method sum (), the method accepts two int parameters, and then returns the result after the addition. We will test this metho

1. JUnit Introduction
JUnit is a Java testing framework for source code development. It is used to write and run reusable tests. It is an example of xUnit, a unit testing framework system (for java ). It is mainly used for white box testing and regression testing.

JUnit unit test (2) -- JUnit Basics
1. Basic Introduction
1. JUnit is a framework for testing code. The purpose of testing is to ensure that the Code is correct, rather than the code is correct.
2. The test class should not be put together with the target class, but the compiled class file should be put together to ensure that the product code is separated from t
JUnit is currently used in a number of large companies or relatively standardized software, and quite a few of the smaller companies do not see the unit test too important. At the big point of the company developers work every day, the first thing is to checkout down the code of their own responsibility from SVN, and then run the unit test, if the unit test passes, then the code is not a problem, then the code block to modify and add, complete and the
Why do you write unit tests?Enterprise development, regardless of the size of the project are inseparable from testing, including unit testing, regression testing, performance testing and so on, and unit testing is to verify that the programmer is the correct way to write code, in the day-to-day development of unit testing is very necessary, imagine if you are developing a huge project, If each of the business logic written by the deployment to the server to run the program through the front int

JUnit 4 parameter tests allow testing methods by parameter values in the change range. To test the parameters, follow these steps:
Add annotation @ runwith (parameterized. Class) to the test class)
Define the parameter to be tested using the variable range parameter value as a private variable.
Use the private variable declared in the previous step as the input parameter to create the constructor.
. Create a public static method using the @ param
Regular Expression and junit test, regular expression junit
You need to know some regular expression statements, and then write the regular expression statements following the rules. Then, it is about junit testing.
After learning about a document you have read, you can take a look at the document, or search for it later.
The regular expression is a string:

Junit 4 allows you to run test classes in bulk by using test suite classes. To create a test suite for a set of test classes, add the following annotations for the test class:
@RunWith (Suite.class) @SuiteClasses (Testclass1.class, Testclass2.class)
When run, all test classes contained within the @suiteclasses annotation are executed. Junit 4 test suite Sample
