### Question:
CreateVolumeOptions extends BaseEC2RequestOptions { public CreateVolumeOptions withIops(Integer iops) { formParameters.put("Iops", checkNotNull(iops, "iops").toString()); return this; }  CreateVolumeOptions withSize(int size); int getSize(); CreateVolumeOptions fromSnapshotId(String snapshotId); String getSnapshotId(); CreateVolumeOptions volumeType(String volumeType); String getVolumeType(); CreateVolumeOptions withIops(Integer iops); Integer getIops(); CreateVolumeOptions isEncrypted(boolean encrypted); boolean getEncrypted();  }### Answer:
@Test public void testWithIops() { CreateVolumeOptions options = new CreateVolumeOptions(); options.withIops(5); assertEquals(options.buildFormParameters().get("Iops"), ImmutableList.of("5")); }
@Test public void testWithIopsStatic() { CreateVolumeOptions options = withIops(5); assertEquals(options.buildFormParameters().get("Iops"), ImmutableList.of("5")); }
