Junit4测试报错

1、字符串数组越界

  java.lang.String IndexOutOfBounds Exception：String index out of range:-1

  导致：

   Transaction rolled back because it has been marked as rollback-only.

 

分析原因：

    String[] params = new String[2];

    params[0] = date;

    params[1] = code;

    int num = getSql(sb.toString(),params);

 

2、数据传输异常

    java.lang.AssertionError:expected:<5> but was :<12>

 

3、比较失败异常

    org.junit.ComparisonFailure:expected : <2014022[1]> but was :<2014022[0]
