@Test

 assertWithMessage("reading within capacity but over size does not increase size")
   .that(parcel.dataSize())
   .isEqualTo(4);

 assertWithMessage("capacity equals requested").that(parcel.dataCapacity()).isEqualTo(100);
 assertWithMessage("size does not increase with capacity").that(parcel.dataSize()).isEqualTo(4);
 parcel.setDataCapacity(404);
 for (int i = 0; i < 100; i++) {
  parcel.writeInt(i);
 }
 assertInvariants();
 assertWithMessage("capacity exactly holds 404 ints").that(parcel.dataCapacity()).isEqualTo(404);
 assertWithMessage("101 ints in size").that(parcel.dataSize()).isEqualTo(404);
 assertWithMessage("advanced 101 ints").that(parcel.dataPosition()).isEqualTo(404);
 parcel.setDataCapacity(12);
 assertWithMessage("capacity never shrinks").that(parcel.dataCapacity()).isEqualTo(404);
 parcel.setDataSize(12);
 assertWithMessage("size does shrink").that(parcel.dataSize()).isEqualTo(12);
 parcel.setDataCapacity(12);
 assertWithMessage("capacity never shrinks").that(parcel.dataCapacity()).isEqualTo(404);
}

parcel.setDataCapacity(500); // Make sure it doesn't affect size.
assertInvariants();
assertWithMessage("truncated size").that(parcel.dataSize()).isEqualTo(8);
