### Question:
PixManagerTransformServiceImpl implements
		PixManagerTransformService { @Override public String getPixAddXml(String c32xml) throws Hl7v3TransformerException { return hl7v3Transformer.transformToHl7v3PixXml(c32xml, Hl7v3Transformer.XSLT_C32_TO_PIX_ADD); }  @Override String getPixAddXml(String c32xml); @Override String getPixUpdateXml(String c32xml); @Override String getPixQueryXml(String c32xml); @Override String getPixXml(PixOperation operation, String c32xml);  }### Answer:
@Test public void testGetPixAddXml() throws Hl7v3TransformerException { String pixAddMock = "pixAddMock"; String c32XmlMock = "c32XmlMock"; when( hl7v3TransformerMock.transformToHl7v3PixXml(c32XmlMock, Hl7v3Transformer.XSLT_C32_TO_PIX_ADD)).thenReturn(pixAddMock); String actualRet = sut.getPixAddXml(c32XmlMock); assertEquals(pixAddMock, actualRet); }
