### Question:
BlobShape extends SimpleShape implements ToSmithyBuilder<BlobShape> { public static Builder builder() { return new Builder(); } private  BlobShape(Builder builder); static Builder builder(); @Override Builder toBuilder(); @Override R accept(ShapeVisitor<R> cases); @Override Optional<BlobShape> asBlobShape();  }### Answer:
@Test public void returnsAppropriateType() { BlobShape shape = BlobShape.builder().id("ns.foo#bar").build(); assertEquals(shape.getType(), ShapeType.BLOB); }
@Test public void mustNotContainMembersInShapeId() { Assertions.assertThrows(SourceException.class, () -> { BlobShape.builder().id("ns.foo#bar$baz").build(); }); }
