Mock static methods from multiple class using PowerMock

Just do @PrepareForTest({Class1.class,Class2.class}) for multiple classes.

@Test
 @PrepareForTest({Class1.class, Class2.class})
 public final void handleScript() throws Exception {
    PowerMockito.mockStatic(Class1.class);
    PowerMockito.mockStatic(Class2.class);

etc...

If you are using kotlin, the syntax is this

@PrepareForTest(ClassA::class, ClassB::class)
