package exercicio13;

import org.junit.Test;

public class FatorialTest {
    @Test
    public void calculaFatorial() {
        assertEquals(1, fatorial(0));
        assertEquals(1, fatorial(1));
        assertEquals(2, fatorial(2));
        assertEquals(6, fatorial(3));
        assertEquals(24, fatorial(4));
        assertEquals(120, fatorial(5));
    }
}


/* Arquivo: Fatorial.java */

package exercicio13;

public class Fatorial {
    public static int fatorial(int numero) {
        if (numero == 0)
            return 1;
        return numero * fatorial(numero - 1);
    }
}

In line 31-33, could it change to:

return (numero == 0) ? 1 : numero * fatorial(numero - 1);

?
