@Test public void test24() { byte[] expected = new byte[] { (byte)0x00, }; assertArrayEquals(expected, Proto.build_filler(1)); }
@Test public void test25() { byte[] expected = new byte[] { (byte)0x00, (byte)0x00, }; assertArrayEquals(expected, Proto.build_filler(2)); }
@Test public void test26() { byte[] expected = new byte[] { (byte)0x1C, (byte)0x1C, }; assertArrayEquals(expected, Proto.build_filler(2, (byte) 0x1C)); }
@Test public void test27() { byte[] expected = new byte[] { (byte)0xFF, (byte)0xFF, }; assertArrayEquals(expected, Proto.build_filler(2, (byte) 0xFF)); }
