| """A module providing the summary for multiple test results. |
| |
| This firmware_summary module is used to collect the test results of |
| multiple rounds from the logs generated by different firmware versions. |
| The test results of the various validators of every gesture are displayed. |
| In addition, the test results of every validator across all gestures are |
| also summarized. |
| |
| Usage: |
| $ python firmware_summary log_directory |
| |
| |
| A typical summary output looks like |
| |
| Test Summary (by gesture) : fw_2.41 fw_2.42 count |
