### Question:
Dependency implements Comparable<Dependency> { public Element getElement(final Document document) { final Element dependencyElement = document.createElement("dependency"); dependencyElement.appendChild(XmlUtils.createTextElement(document, "groupId", groupId)); dependencyElement.appendChild(XmlUtils.createTextElement(document, "artifactId", artifactId)); dependencyElement.appendChild(XmlUtils.createTextElement(document, "version", version)); if (type != null && type != DependencyType.JAR) { String typeContent = ""; if (type == DependencyType.TESTJAR) { typeContent = "test-jar"; } else { typeContent = type.toString().toLowerCase(); } final Element typeElement = XmlUtils.createTextElement(document, "type", typeContent); dependencyElement.appendChild(typeElement); } if (scope != null && scope != DependencyScope.COMPILE) { dependencyElement.appendChild(XmlUtils.createTextElement(document, "scope", scope.toString() .toLowerCase())); if (scope == DependencyScope.SYSTEM && StringUtils.isNotBlank(systemPath)) { dependencyElement.appendChild(XmlUtils .createTextElement(document, "systemPath", systemPath)); } } if (StringUtils.isNotBlank(classifier)) { dependencyElement.appendChild(XmlUtils.createTextElement(document, "classifier", classifier)); } if (StringUtils.isNotBlank(optional)) { dependencyElement.appendChild(XmlUtils.createTextElement(document, "optional", optional)); } if (!exclusions.isEmpty()) { final Element exclusionsElement = DomUtils.createChildElement("exclusions", dependencyElement, document); for (final Dependency exclusion : exclusions) { final Element exclusionElement = DomUtils.createChildElement("exclusion", exclusionsElement, document); exclusionElement.appendChild(XmlUtils.createTextElement(document, "groupId", exclusion.getGroupId())); exclusionElement.appendChild(XmlUtils.createTextElement(document, "artifactId", exclusion.getArtifactId())); } } return dependencyElement; } Dependency(final Element dependency);  Dependency(final GAV gav, final DependencyType type, final DependencyScope scope);  Dependency(final String groupId, final String artifactId, final String version);  Dependency(final String groupId, final String artifactId, final String version,
      final Collection<? extends Dependency> exclusions);  Dependency(final String groupId, final String artifactId, final String version,
      final DependencyType type, final DependencyScope scope);  Dependency(final String groupId, final String artifactId, final String version,
      final DependencyType type, final DependencyScope scope, final String classifier); static boolean isHigherLevel(final String type1, final String type2); void addExclusion(final String exclusionGroupId, final String exclusionArtifactId); int compareTo(final Dependency o); @Override boolean equals(final Object obj); String getArtifactId(); String getClassifier(); Element getElement(final Document document); List<Dependency> getExclusions(); String getGroupId(); DependencyScope getScope(); String getSimpleDescription(); String getSystemPath(); DependencyType getType(); String getVersion(); @Deprecated String getVersionId(); @Override int hashCode(); boolean hasSameCoordinates(final Dependency dependency); @Override String toString();  }### Answer:
@Test public void testGetElementForMinimalDependency() { final Dependency dependency = new Dependency(DEPENDENCY_GROUP_ID, DEPENDENCY_ARTIFACT_ID, DEPENDENCY_VERSION); final Element element = dependency.getElement(DOCUMENT_BUILDER.newDocument()); assertXmlEquals(EXPECTED_ELEMENT_FOR_MINIMAL_DEPENDENCY, element); }
