XML and Case Class I compare the library scalaxb and XStream. It seems to me that XStream is more easy to use. Here is first step to add the dependencies. "com.thoughtworks.xstream" % "xstream" % "1.4.8","org.joda" % "joda-convert" % "1.7",The Trait object to deal with the xstream base class. package com.sillycat.jobsconsumer.utilities import com.sillycat.jobsconsumer.models.Job import com.thoughtworks.xstream.XStream import com.thoughtworks.xstream.io.xml.DomDriver trait IncludeXMLMapping { var xStream : XStream = new XStream(new DomDriver()) xStream.alias("job",classOf[Job]) def toXML(obj:Any): String ={ xStream.toXML(obj) } def fromXML(xml:String):Any = { xStream.fromXML(xml) } } Here is the Test Class package com.sillycat.jobsconsumer.models import com.sillycat.jobsconsumer.utilities.{IncludeXMLMapping} import org.scalatest.{BeforeAndAfter,Matchers,FunSpec} class JobXMLSpec extends FunSpec with Matchers with BeforeAndAfter with IncludeXMLMapping { describe("JobXMLMapping") { describe("#xml2object"){ it("Convert xml string to object") { val xml = """<job> | <id>id1</id> | <title>title1</title> | <desc>desc1</desc> | <industry>sales</industry> |</job>""".stripMargin val job1 = fromXML(xml).asInstanceOf[Job] job1.title should be ("title1") } } describe("#object2xml"){ it("Convert object to xml string") { val job1 = Job("id1","title1","desc1","sales") val expect = """<job> | <id>id1</id> | <title>title1</title> | <desc>desc1</desc> | <industry>sales</industry> |</job>""".stripMargin val xml = toXML(job1) xml should be (expect) } } } } Tip Warning Message [warn] Class java.time.Duration not found - continuing with a stub. [warn] Class java.time.Duration not found - continuing with a stub. [warn] two warnings found Solution: Adding package dependency fixes the problem.
