Answer 1

Using PowerMockito:

@RunWith(PowerMockRunner.class)
@PrepareForTest({Log.class})
public class TestsToRun() {
    @Test
    public void test() {
        PowerMockito.mockStatic(Log.class);
    }
}

And you're good to go. Be advised that PowerMockito will not automatically mock inherited static methods, so if you want to mock a custom logging class that extends Log, you must still mock Log for calls such as MyCustomLog.e().
