public TableName getTableName() {
    return tableName;
  }
Helper to handle parameterized method names. Unlike regular test methods, parameterized method
names look like 'foo[x]'. This is problematic for tests that use this name for HBase tables.
This helper strips out the parameter suffixes.
@return current test method name with out parameterized suffixes.
