initializationError(org.junit.runner.manipulation.Filter), No tests found matching型异常

package soundsystem;
import static org.junit.Assert.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = CDPlayerConfig.class)
public class CDPlayerTest {
@Autowired
private CompactDisc cd;
@Test
public void cdShouldNotBeNull(){
assertNotNull(cd);
}
}

在进行一个简单的Junit测试的时候报异常，测试不能正确通过。

使用的Spring-framework版本是4.3.4，Junit版本是4.12，测试一直不通过，报出下面这样的异常：

CDPlayerTest.cdShouldNotBeNull
initializationError(org.junit.runner.manipulation.Filter)
java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=cdShouldNotBeNull], {ExactMatcher:fDisplayName=cdShouldNotBeNull(soundsystem.CDPlayerTest)], {LeadingIdentifierMatcher:fClassName=soundsystem.CDPlayerTest,fLeadingIdentifier=cdShouldNotBeNull]] from org.junit.internal.requests.ClassRequest@27f8302d

在网上查找资料时，好多说忘记加@Test注解也会报这个类型的错误，在测试已经成功的条件下，去掉@Test注解，果然报了同样的错误。

CDPlayerTest.cdShouldNotBeNull
initializationError(org.junit.runner.manipulation.Filter)
java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=cdShouldNotBeNull], {ExactMatcher:fDisplayName=cdShouldNotBeNull(soundsystem.CDPlayerTest)], {LeadingIdentifierMatcher:fClassName=soundsystem.CDPlayerTest,fLeadingIdentifier=cdShouldNotBeNull]] from org.junit.internal.requests.ClassRequest@73a28541

首先考虑是否忘记@Test注解；如果不是，再考虑是否是框架版本不匹配问题，更换版本后，一般都能解决问题。
