### Question:
VariableRow { public void setDataTypeDisplayName(final String dataTypeDisplayName) { this.dataTypeDisplayName = dataTypeDisplayName; } VariableRow();  VariableRow(final Variable.VariableType variableType,
                       final String name,
                       final String dataTypeDisplayName,
                       final String customDataType);  VariableRow(final Variable variable,
                       final Map<String, String> mapDataTypeNamesToDisplayNames);  VariableRow(final Variable.VariableType variableType,
                       final String name,
                       final String dataTypeDisplayName,
                       final String customDataType,
                       final List<String> tags); List<String> getTags(); void setTags(List<String> tags); long getId(); void setId(final long id); Variable.VariableType getVariableType(); void setVariableType(final Variable.VariableType variableType); String getName(); void setName(final String name); String getDataTypeDisplayName(); void setDataTypeDisplayName(final String dataTypeDisplayName); String getCustomDataType(); void setCustomDataType(final String customDataType); @Override boolean equals(final Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void setDataTypeDisplayName() { VariableRow tested = new VariableRow(); tested.setDataTypeDisplayName(DATA_TYPE_DISPLAY_NAME); assertEquals(DATA_TYPE_DISPLAY_NAME, tested.dataTypeDisplayName); }
