Wrote a test that raises CitrusRuntimeException which is working fine as parallel block does not support assertion errors right now. Going to fix that!

<template name="textMatch">
  <groovy>
    <![CDATA[
      import com.consol.citrus.exceptions.CitrusRuntimeException
      if (${text1} != ${text2}) {
        throw new CitrusRuntimeException("Text did not match")
      }
    ]]>
  </groovy>
</template>

<testcase name="ParallelFailureTest">
  <actions>
    <assert exception="com.consol.citrus.exceptions.CitrusRuntimeException"
            message="Text did not match">
      <parallel>
        <echo>
          <message>Test failure in call template</message>
        </echo>

        <call-template name="textMatch">
