错误总结

1. Junit-4.11 使用报java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing

官方文档说明：

junit.jar: Includes the Hamcrest classes. The simple all-in-one solution to get started quickly.Starting with version 4.11, Hamcrest is no longer included in this jar.

junit-dep.jar: Only includes the JUnit classes but not Hamcrest. Lets you use a different Hamcrest version.

 

注意黑色加下划线的部分，说明4.1.1中没有hamcrest包了。最好的解决方法是：

使用是导入包的方案：junit.jar + hamcrest-core.jar + hamcrest-library.jar

或者是：junit-dep.ajr+hancrest-all.jar
