Junit 測試常見錯誤

1.java

java.lang.Exception: No tests found matching Method deleteUser(mybatis.dao.Usertest) from org.junit.internal.requests.ClassRequest@a1bf24b
沒有添加@test 標籤sql

 2.apache

org.apache.ibatis.exceptions.PersistenceException:
### Error updating database. Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for test.deleteUser
### Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for test.deleteUsermybatis


  sqlSession.delete("test.deleteUser", 1);路徑設置和mapper.xml 路徑不一致。 正確寫法 sqlSession.delete("mybatis.po.deleteUser", 1);app

 <mapper namespace="mybatis.po">spa

      <delete id="deleteUser" parameterType="java.lang.Integer">
      delete from user where id=#{id}
       </delete>xml

</mapper>requests

3.it

java.io.IOException: Could not find resource mybatis.po.xml  
mybatis配置文件名字寫錯。io

4.

org.apache.ibatis.exceptions.PersistenceException:
### Error updating database. Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for test.delete
### Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for test.delete
Caused by: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for test.delete
下面的紅字地方有誤:

sqlSession.delete("test.deleteUser",12);
