```java
public void testTruncateCQ() throws Exception {
{
Test Case
}
{
Test Case
}
...
}
```
由于他们复用了一个数据目录，而在第一个测试用例执行的时候，程序依然占用着数据目录中的文件句柄，导致第二个测试用例在删除文件时失败，最终断言失败：
```java
DefaultMessageStore messageStore = createDledgerMessageStore(base, group,
"n0", peers, null, false, 0); // 此时创建了24个文件
```
```java
DefaultMessageStore messageStore = createDledgerMessageStore(base, group,
"n0", peers, null, false, 4); // 删除4个
```
执行结果如下：
```bash
java.lang.AssertionError:
Expected :20
Actual :24
...
```
操作系统：Windows 10 (Linux 无此问题)
