@Sescandell must provide you an image (If ever: DĂ©veloppeur Gladys : Comment builder une image Docker de test? )
Not in this case 
In the case of this test, you could even run the Docker container on your PC since this test doesn’t use any « hardware ». You will just connect your test Gladys to your Z-WaveJS broker (from production, in the case of this test that’s not a problem), and then see if Gladys handles your Fibaro eye correctly
