How to mock Hawk library using Mockito?

I'm trying to do some unit testing with Mockito. Because I'm using Hawk library as SharedPreference to apply some constraints when I do my API calls, every time I run a test that implies an API call I get a NullPointerException because Hawk is not initialized.

By default the library is initialized on the Application class level:

Hawk.init(context).build();

Although I'm using a mocked context to initialize Hawk in my test class, as in the following snippet:

@Mock
private lateinit var context: Context

@Before
fun initMocks() {
    MockitoAnnotations.initMocks(this)
    Hawk.init(context).build()
}

I keep getting this error message:

Is there a way to mock the Hawk library using Mockito?
