Execute command from behave acceptance test
Feature: Tracing
Scenario Outline: Generating a two column CSV
When I execute: my_fictional_command input1.xml input2.xml --header=COL1;COL2
Then the generated csv with <COL1> should map to <COL2>
Examples: COL1 maps to COL2
| REQ_ID| RELATED_ID |
| COL1| COL2 |
| A | 1 |
| B | 2 |
| C | 3 |
