Why can't I use the @test annotation after introducing JUnit

stay pom.xml The following are configured in the configuration file

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

Found to be unusable @Test、@after wait

reason ： Above scope Configured with Junit Available locations ,test Indicates that the src Under the test Only under the folder can you use .

solve ： take <scope>test</scope> Delete it .
