The failure would maks the root cause. In most of the cases, I want to know the exact expected/actual value rather than just the fact "it should not be null".

Have you considered something like the following?

```java
Integer actual = rs.wasNull() ? null : rs.getInt("CHAR_OCTET_LENGTH");
assertEquals(expected, actual, ...);
```
