好像是类冲突，有重复的类引起的。一个DubboNamespaceHandler.class文件存在于多jar中。
解决方案二：
Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.//这句话是说连接你本机的5432端口被拒绝然后让你检查主机名和端口是否正确。
解决方案三：
我的也报错，。。。求各位大神指导
解决方案四：

解决方案五：
从下网上看 [main] ERROR org.springframework.test.context.TestContextManager

JUnit 4 如何正确测试异常
发表于： 10:43 &作者：元月六号 & 来源：51Testing软件测试网采编
推荐标签：
　　try...catch 测试异常失败时，得到的提示:　　无异常时：　　java.lang.AssertionError: No exception thrown.　　at org.junit.Assert.fail(Assert.java:91)　　at cc.unmi.PasswordTest.passwordLengthLessThan6LettersThrowsException(PasswordTest.java:20)　　异常类型不对或异常的 message 不对时：　　java.lang.AssertionError:　　at org.junit.Assert.fail(Assert.java:91)　　at org.junit.Assert.assertTrue(Assert.java:43)　　at org.junit.Assert.assertTrue(Assert.java:54)　　at cc.unmi.PasswordTest.passwordLengthLessThan6LettersThrowsException(PasswordTest.java:22)　　上面能提供给我们的定位错误的帮助不是特别大　　再看 @Test(expected=InvalidPasswordException.class) 时测试失败时的提示：　　java.lang.AssertionError: Expected exception: cc.unmi.InvalidPasswordException　　at org.junit.internal.runners.statements.ExpectException.evaluate(ExpectException.java:32)　　at org.junit.rules.ExpectedException$ExpectedExceptionStatement.evaluate(ExpectedException.java:110)　　用 @Rules ExpectedException方式来测试异常，失败时的提示：　　java.lang.AssertionError:　　Expected: (exception with message a string containing "YES. required" and an instance of java.lang.NullPointerException)　　got: &cc.unmi.InvalidPasswordException: Password is required.&　　at org.junit.Assert.assertThat(Assert.java:778)　　at org.junit.Assert.assertThat(Assert.java:736)　　at org.junit.rules.ExpectedException$ExpectedExceptionStatement.evaluate(ExpectedException.java:114)　　特别是 @Rules &ExpectedException 方法时为何测试失败提示的清清楚楚。期望什么异常，异常 message 中含何字符串，实际上确得到什么类型的异常，异常中 message 是什么。有了这，你一看到就知道怎么去修补你的程序。　　所以到了这里，我们真的没理由不用 @Test(expected=...) 或 &@Rule ExpectedException 的写法了。

采纳的答案
java.lang.ClassNotFoundException: test.UserTest&
为什么找不到你自己写的单元测试类？没放进去？
你用什么方式运行单元测试的？改用其他方式也是这样吗？
我遇见过这样的情况，发现时Eclipse被编译，建议你重新clean一次Eclipse工程，
重新Build一次
晕死，测试方法应该这样写& test+方法名& 例如 testadduser（）{}
