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]
