jafka学习之LogManager
前面还记得有前辈说过看一个开源项目在不懂的情况下要去努力的去看它的单元测试,这样就能更好的领悟作者的思想。首先我们先看一下单元测试用的一些xml。
<!-- Test1.xml --> <?xml version="1.0"?> <employee firstName="First Name" lastName="Last Name"> <address type="home" street="Home Street" city="Home City" state="HS" zipCode="HmZip"/> <address type="office" street="Office Street" city="Office City" state="OS" zipCode="OfZip"/> </employee>
首先来看第一个单元测试:
package org.apache.commons.digester; import java.io.InputStream; import java.io.IOException; import junit.framework.Test; import junit.framework.TestCase; import junit.framework.TestSuite; /** * <p>Test Case for the Digester class.
