ValidValue extends Referenceable { @Override public String toString() { return "ValidValue{" + "displayName='" + displayName + '\'' + ", description='" + description + '\'' + ", usage='" + usage + '\'' + ", scope='" + scope + '\'' + ", preferredValue='" + preferredValue + '\'' + ", isDeprecated='" + isDeprecated + '\'' + ", qualifiedName='" + qualifiedName + '\'' + ", additionalProperties=" + additionalProperties + ", meanings=" + meanings + ", type=" + type + ", guid='" + guid + '\'' + ", url='" + url + '\'' + ", classifications=" + classifications + ", extendedProperties=" + extendedProperties + '}'; } ValidValue();  ValidValue(ValidValue template); String getDisplayName(); void setDisplayName(String displayName); String getDescription(); void setDescription(String description); String getUsage(); void setUsage(String usage); String getScope(); void setScope(String scope); String getPreferredValue(); void setPreferredValue(String preferredValue); boolean isDeprecated(); void setDeprecated(boolean deprecated); @Override String toString(); @Override boolean equals(Object objectToCompare); @Override int hashCode();  }### Answer:
@Test public void testToString() { assertTrue(getTestObject().toString().contains("ValidValue")); assertTrue(getSetTestObject().toString().contains("ValidValueSet")); assertTrue(getDefinitionTestObject().toString().contains("ValidValueDefinition")); }
