Junit入门到掌握-17-JUnit集成-命令行运行junit用例

桃扇骨 2021-12-17 04:35 568阅读 0赞

这篇来学习命令行如何执行Junit测试用例，其实就是一个很长的命令，我们需要分步骤地去拼接这个命令，最后这些步骤其实都是可以通过自动化完成。

**1.下载Junit jar包**

去[https://github.com/junit-team/junit4/wiki/Download-and-Install][https_github.com_junit-team_junit4_wiki_Download-and-Install]

下载两个包

其实这两个jar在我们eclipse上项目中都有

把这两个放在一个文件夹下，例如

**2.Eclipse上打包成jar**

选择Junit这个工程，右键-export-jar类型，记得勾选下面两个项目

记得选择一个路径，并取一个名字，例如xxx.jar。剩下的就是一直点击Next，直到结束。

**3.cmd运行单元测试命令**

打开cmd，输入如下命令,以下 -cp 是指 classpath

java -cp D:\junit\libs\*;D:\junit\ProteinTracker.jar org.junit.runner.JUnitCore test.TrackingServiceTests

我这边的执行纪录

C:\Users\Anthony>java -cp D:\junit\libs\*;D:\junit\ProteinTracker.jar org.junit.runner.JUnitCore test.TrackingServiceTests
    JUnit version 4.13-beta-3
    Before class, Onln Once
    .Before Method
    After Method
    .Before Method
    After Method
    E.Before Method
    After Method
    .Before Method
    After Method
    .Before Method
    After Method
    After class, only once
    
    Time: 0.116
    There was 1 failure:
    1) badTest(test.TrackingServiceTests)
    org.junit.runners.model.TestTimedOutException: test timed out after 20 milliseconds
            at test.TrackingServiceTests.badTest(TrackingServiceTests.java:62)
    
    FAILURES!!!
    Tests run: 5,  Failures: 1

这个我们只是运行了一个用例，下面来看看一个TestSuite如何在cmd中运行

C:\Users\Anthony>java -cp D:\junit\libs\*;D:\junit\ProteinTracker.jar org.junit.runner.JUnitCore test.ProteinTrackerSuite
    JUnit version 4.13-beta-3
    .Run Hello Junit
    .EBefore class, Onln Once
    .Before Method
    After Method
    .Before Method

    E.Before Method
    After Method
    .Before Method
    After Method
    .Before Method
    After Method
    After class, only once
    
    Time: 0.1
    There were 2 failures:

这种确实是在持续集成中的一个选择，只要安装了java，我就可以运行JUnit单元测试，不管是在win还是linux机器上都可以实现，把这个挂在jenkins上实现持续的单元测试。打包成jar是可以通过命令完成的，具体路径也是代码里可以指定的，这一切都可以实现自动化操作。
