Mon May 24 21:13:08 CEST 2021


Refactor lc-compliance using Googletest as the test framework.

Signed-off-by: Nícolas F. R. A. Prado <nfraprado at collabora.com>
Reviewed-by: Niklas Söderlund <niklas.soderlund at ragnatech.se>
---
Changes in v5:
- Thanks to Laurent:
  - Fixed style issues
  - Added SetUp and TearDown functions to acquire and release the camera for
    each test

Changes in v4:
- Removed old lc-compliance results classes
- Thanks to Niklas:
  - Improved naming of tests

Changes in v3:
- Thanks to Niklas:
  - Went back to static test registration, and created a Singleton Environment
    class to store the camera global variable
- Added a nameParameters() function to give meaningful names to the test
  parameters, removing the need to register each test suite for every role
