White box Test (Java)-(JUnit introductory article i)

　Company development programmers have a lot of beautiful women, and then we are not to be outdone. The study of JUnit, belonging to just contact, did a bit of note-sharing. Only suitable small white articles, have been the entry of the negligible

First, the required tools:

1. There are eclipse 4.3 64-bit (or other Java development tools), download path: Http://pan.baidu.com/s/1qYLVumo;

2. Install the JDK, I installed the 1.8 version, the configuration of the environment (network not to share, to download their own website);

3. jar package with junit4.12, for: Http://pan.baidu.com/s/1i548ACP;

Ii. Creation of the project

My project package structure is as follows:

1. Open Eclipse and create a new Java project package;

2. Import the JUnit package;

Select Java Project Package-right--->properties-->java Bulid path-->libraries-->add External jars...-->junit4.12 within the 2 jar package---OK

is the imported successful picture:

3. Create a new package, and class;

The code for the class is as follows:

1  PackageTestjunit.liang;2 3  Public classUser {4     5     //Define Age6      Public intAgeintAge ) {7         8         returnAge ;9             Ten     } One     //Define name A      Publicstring Name (string name) { -          -         returnname;  the          -     } -     //Define gender -      Publicstring Sex (String sex) { +          -         returnsex;  +          A     } at}

3. Create a new package, class, tested and validated with JUnit;

The code is as follows:

1  Packagetestjunit.test;2 3 ImportOrg.junit.Assert;4 Importorg.junit.Test;5 6 ImportTestJunit.liang.User;7 8  Public classTestuserjunit {9     TenUser User =NewUser (); One      A @Test -      Public voidTestage () { -         //Assign Value the         intAge = User.age (18); -         //adding assertions -Assert.assertequals (age, 18); -     } + @Test -      Public voidtestname () { +String name = User.Name ("Light Rain");  AAssert.assertequals (name, "Light Rain"); at     } - @Test -      Public voidTestsex () { -String sex = user.sex ("female");  -Assert.assertequals (Sex, "female"); -     } in  -  to}

In the back of this class, check-right-click and select runs As-->junit Test

The results are as follows:

Third, Code Analysis

1.Junit package After the successful import, write the test class, before each method to add @test, otherwise, the test will not run the method.

If the following 2 methods are annotated, only one method will be run when running.
