I don't think that it's correct to add `INTEGER` and `INT` to `decimalTypes` here. `decimalTypes` are later mapped to `java.sql.Types.NUMERIC`. In the [MySQL dbfit driver, `INTEGER` and `INT` are mapped to `java.sql.Types.INTEGER`](https://github.com/benilovj/dbfit/blob/master/dbfit-java/mysql/src/main/java/dbfit/environment/MySqlEnvironment.java#L94) - I'd try that mapping.
