白盒测试和黑盒测试试验报告

本文格式为Word版，下载可任意编辑——白盒测试和黑盒测试试验报告的对象相关事件，方法包括测试开始startTest(Testtest)，测试终止endTest(Testtest),错误，增加异常addError(Testtest,Throwablet)和增加失败addFailure(Testtest,AssertionFailedErrort)

TestFailure失败类是个―失败‖状况的收集类，解释每次测试执行过程中出现的异常状况。其toString()方法返回―失败‖状况的简要描述4.利用Junit开发一个简单的Java程序

（1）File-new-Javaproject，名称为“HelloWorldWithJUnit〞建立两个文件夹，分别为src和junittestsrc存放实现主要功能的文件junittest存放测试功能文件

（2）创立测试类

选中“HelloWorldWithJUnit〞项目中的junittest包文件夹，new-other-Junit-JunitTestCase

右键并选择

（3）选择“next〞，在NewJunitTestCase中的name中输入“HelloWorldTest〞，在package中输入“junittest〞，然后单击“finish〞。

（4）现在初步计划被测试文件功能十分简单，只有一个方法ReturnValue，作用是返回“HelloWorld〞，所以测试类中有对ReturnValue这个方法进行测试的类。当然，测试要能进行，该测试类必需为主类，存在main方法。HelloWorldTest.java的源代码如下：

选择run-runas-Junittest

弹出一个Junit窗口，发现在该窗口中有一个红条，这说明存在错误。（5）创立HelloWorld类

建立一个HelloWorld类，并输入以下代码：

（6）在HelloWorldTest.java中参与importsrc.*;

此时以Junit测试的方式来运行HelloWorldTest.java，出现了含有绿色的窗口，测试成功。

Showview->other，可以看到Clover的信息：

2．还需要导入clover.license。从Preferences->Clover->License进入：

并将申请到的的license粘帖到这里，至此Clover已经安装完成，开始进入单元测试。

3.可以对之前已经做过的project进行覆盖率的计算。也可新建了一个project，结构如下：

Sample.java和SampleTest.java内容分别是：

Java代码

1.packagecom.lyoe.sample;2.

3.publicclassSample{
