| 4 | It helps to improve the user experience of the software application | It helps to identify compatibility issues with other software applications or software systems. |
| 5 | To Execute these tests does not require knowledge of the underlying technology or software stack | To Execute these tests requires knowledge of the underlying technology or software stack. |
| 6 | These Tests Emphasizes on what the software should do. | These Tests emphasizes on how the software works with other components. |
