$this->anyMock
    ->expects($this->exactly(4))
    ->method('doSomething')
    ->withConsecutive(...$args)
    ->willReturnOnConsecutiveCalls(...$results)

1. Создавать мок именно в методе, не злобоупотреблять setUp()
   
2. Контроллировать число вызовов в методе и аргументов для Consecutive Calls, в этом поможет expects($this->exactly(N))
