【笔记】Eclipse and Java for Total Beginners—004

Lesson 04 – JUnit Testing in Eclipse, Part 1

• Create test source folder
• Create Person Test class
• Run first JUnit test

1. Scrapbook的优/缺点

• Great for exploring new Java classes and trying commmands.
• Does not let you automate testing

2. Unit Testing的特点

• Automated testing of all methods
• Very valuable when making changes to code
• Key element of agile software development
• Unit testing support built-in to Eclipse

3. 把test classes和application code放在不同的目录，好处易见。首先，为test classes创建一个文件夹

    Select Project / File / New / Source folder / test (Folder name) / Finish.

4. 接下来，想把test classes放在和被测试的classes同一个package里，所以在test目录下创建一个同名的package。

    Select test / File / New / Package / org.totalbeginner.tutorial (name) / Finish .

5. 接着，创建第1个JUnit test。

    选择刚创建的package / RC org.totalbeginner.tutorial / New / JUnit test cae / PersonTest (name) / Person (Class under test ）/ Next / 勾选 Person, setName, setMaximumBooks.

这里需要指定libray的路径。

6. 指定library的路径

    方法1：Quick Fix

              右击或Ctrl+1.

    方法2：RC TotalBeginner / Build Path / Configure Build path.. / Libraries / Add Library.

7. 运行一下test。

    Run / Run As / JUnit Test.
