test: Add test cases to cover brightness and asserted values

This commit adds test cases that will validate:

 ┌────────────┬──────────┬────────────────────────┐
 │ brightness │ asserted │ brightness && asserted │
 ├────────────┼──────────┼────────────────────────┤
 │     0      │    0     │           0            │
 │     0      │    1     │           0            │
 │     1      │    0     │           0            │
 │     1      │    1     │           1            │
 └────────────┴──────────┴────────────────────────┘

where:
getMaxBrightness() would map to asserted value
getBrightness() would map to brightness value
