| 47 | * @short_description: Library for using the Chamelium into igt tests |
| 48 | * @title: Chamelium |
| 49 | * @include: igt_chamelium.h |
| 50 | * |
| 51 | * This library contains helpers for using Chameliums in IGT tests. This allows |
| 52 | * for tests to simulate more difficult tasks to automate such as display |
| 53 | * hotplugging, faulty display behaviors, etc. |
| 54 | * |
| 55 | * More information on the Chamelium can be found |
| 56 | * [on the ChromeOS project page](https://www.chromium.org/chromium-os/testing/chamelium). |
| 57 | * |
| 58 | * In order to run tests using the Chamelium, a valid configuration file must be |
Paul Kocialkowski | ebd6eb6 | 2017-07-04 16:33:19 +0300 | [diff] [blame] | 59 | * present. It must contain Chamelium-specific keys as shown with the following |
| 60 | * example: |

| 67 | * # This is required so any tests using the Chamelium know which connector |
| 68 | * # on the test machine should be connected to each Chamelium port. |
| 69 | * # |
| 70 | * # In the event that any of these mappings are specified incorrectly, |
