本文介绍了如何使用apache-poi java为将数据写入word文档的类编写单元测试?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我用 apache-poi(poi-ooxml 3.15 版)创建了一个 word 文档，现在我想为我的类编写单元测试.最好的方法是什么?我们在我们的项目中使用 mockito(2.15.0).
I created a word-document with apache-poi (poi-ooxml version 3.15) and now I want to write unit tests for my classes. What is the best way to do that? We're using mockito(2.15.0) in our project.
这是我正在尝试为其编写测试的类之一:
This is one of the classes I'm trying to write test for:
@Component
public class ProffesionalSumaryService {
public void populateDocumentWithProfileSkills(XWPFDocument document, ExportProfileDTO profileData){
XWPFTable antet = document.createTable();
antet.getCTTbl().getTblPr().getTblBorders().getBottom().setColor(COLOR_OF_TABLE_BORDERS);
antet.getCTTbl().getTblPr().getTblBorders().getRight().setColor(COLOR_OF_TABLE_BORDERS);
antet.getCTTbl().getTblPr().getTblBorders().getLeft().setColor(COLOR_OF_TABLE_ANTET_BACKGROUND);
antet.getCTTbl().getTblPr().getTblBorders().getTop().setColor(COLOR_OF_TABLE_ANTET_BACKGROUND);
CTTblWidth ctTblWidth = antet.getCTTbl().getTblPr().getTblW();
ctTblWidth.setType(STTblWidth.PCT);
ctTblWidth.setW(BigInteger.valueOf(6*TWIPS_PER_INCH));
XWPFTableRow antetRow = antet.getRow(0);
antetRow.getCell(0).removeParagraph(0);
XWPFParagraph professionalSkills = antetRow.getCell(0).addParagraph();
setStyles(professionalSkills.createRun() , FONT_CALIBRI ,SUBTITLE_FONT_SIZE , COLOR_FORTECH , "Professional Summary" , true, false);
antetRow.getCell(0).setColor(COLOR_OF_TABLE_ANTET_BACKGROUND);
XWPFParagraph paragraphSkills = document.createParagraph();
XWPFTable skillsTable = document.createTable();
skillsTable.getCTTbl().getTblPr().getTblBorders().getBottom().setColor(COLOR_OF_TABLE_BORDERS);
skillsTable.getCTTbl().getTblPr().getTblBorders().getTop().setColor(COLOR_OF_TABLE_BORDERS);
skillsTable.getCTTbl().getTblPr().getTblBorders().getLeft().setColor(COLOR_OF_TABLE_BORDERS);
skillsTable.getCTTbl().getTblPr().getTblBorders().getRight().setColor(COLOR_OF_TABLE_BORDERS);
skillsTable.getCTTbl().addNewTblGrid().addNewGridCol().setW(BigInteger.valueOf(COLUMN_WIDTH_SMALL));
skillsTable.getCTTbl().getTblGrid().addNewGridCol().setW(BigInteger.valueOf(COLUMN_WIDTH_BIG));
XWPFTableRow projectSkillsRow = skillsTable.getRow(0);
XWPFParagraph _skills = projectSkillsRow.getCell(0).addParagraph();
setStyles(_skills.createRun(), FONT_CALIBRI , FONT_SIZE_NORMAL, COLOR_FORTECH , "Skills" , false, false);
projectSkillsRow.createCell();
try{
setSkillsBulletList(profileData.getSkillList(),document,projectSkillsRow);
}catch(XmlException e){
throw new RestExceptions.HeaderError();
}
}
protected void setSkillsBulletList(List<SkillEntity> skillEntities, XWPFDocument document, XWPFTableRow projectSkillsRow) throws XmlException {
String cTAbstractNumBulletXML =
"<w:abstractNum xmlns:w=\"http://schemas.openxmlformats.org/wordprocessingml/2006/main\" w:abstractNumId=\"0\">"
+ "<w:multiLevelType w:val=\"hybridMultilevel\"/>"
+ "<w:lvl w:ilvl=\"0\"><w:start w:val=\"1\"/><w:numFmt w:val=\"bullet\"/><w:lvlText w:val=\"\"/><w:lvlJc w:val=\"left\"/><w:pPr><w:ind w:left=\"720\" w:hanging=\"360\"/></w:pPr><w:rPr><w:rFonts w:ascii=\"Symbol\" w:hAnsi=\"Symbol\" w:hint=\"default\"/></w:rPr></w:lvl>"
+ "<w:lvl w:ilvl=\"1\" w:tentative=\"1\"><w:start w:val=\"1\"/><w:numFmt w:val=\"bullet\"/><w:lvlText w:val=\"o\"/><w:lvlJc w:val=\"left\"/><w:pPr><w:ind w:left=\"1440\" w:hanging=\"360\"/></w:pPr><w:rPr><w:rFonts w:ascii=\"Courier New\" w:hAnsi=\"Courier New\" w:cs=\"Courier New\" w:hint=\"default\"/></w:rPr></w:lvl>"

+ "</w:abstractNum>";
XWPFRun run;
CTNumbering cTNumbering = CTNumbering.Factory.parse(cTAbstractNumBulletXML);
CTAbstractNum cTAbstractNum = cTNumbering.getAbstractNumArray(0);
XWPFAbstractNum abstractNum = new XWPFAbstractNum(cTAbstractNum);
XWPFNumbering numbering = document.createNumbering();
BigInteger abstractNumID = numbering.addAbstractNum(abstractNum);
BigInteger numID = numbering.addNum(abstractNumID);
projectSkillsRow.getCell(1).removeParagraph(0);
if(skillEntities.size() != 0)
for (SkillEntity skill : skillEntities) {
XWPFParagraph item = projectSkillsRow.getCell(1).addParagraph();
item.setNumID(numID);
run = item.createRun();
run.setText(skill.getSkillDescriptionEntity().getName() + " - " + SKILL_SCORES.values()[skill.getSkillScore()]);
}
else {
XWPFParagraph item = projectSkillsRow.getCell(1).addParagraph();
run = item.createRun();
run.setText("No skills");
}
}
private static void setStyles(XWPFRun run , String fontFamily , int fontSize , String colorRGB , String text , boolean bold , boolean addBreak) {
run.setFontFamily(fontFamily);
run.setFontSize(fontSize);
run.setColor(colorRGB);
run.setText(text);
run.setBold(bold);
if (addBreak) run.addBreak();
}
}
这是我迄今为止发现和尝试的:
And this is what I've found and tried until now:
@RunWith(MockitoJUnitRunner.class)
public class ProffesionalSumaryServiceTest {
private static final String UID = "uid";
private static final int SKILL_SCORE = 3;
@InjectMocks
ProffesionalSumaryService proffesionalSumaryService;
ExportProfileDTO exportProfileDTO;
XWPFDocument mockDocument;
XWPFTable mockTable;
XWPFTableRow mockRow;
XWPFParagraph mockParagraph;
XWPFTableCell mockCell;
XWPFRun mockRun;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
exportProfileDTO = makeExportProfileDto();
mockDocument = mock(XWPFDocument.class);
mockTable = mock(XWPFTable.class, Mockito.RETURNS_DEEP_STUBS);
mockRow = mock(XWPFTableRow.class);
mockParagraph = mock(XWPFParagraph.class);
mockCell = mock(XWPFTableCell.class);
mockRun = mock(XWPFRun.class);
}
@Test
public void populateDocumentWithProfileSkills() {
CTBorder mockCTBorder = mock(CTBorder.class);
CTTblWidth mockCTTblWidth = mock(CTTblWidth.class);
when(mockDocument.createTable()).thenReturn(mockTable);
when(mockTable.getCTTbl().getTblPr().getTblBorders().getBottom()).thenReturn(mockCTBorder);
when(mockTable.getCTTbl().getTblPr().getTblBorders().getTop()).thenReturn(mockCTBorder);
when(mockTable.getCTTbl().getTblPr().getTblBorders().getLeft()).thenReturn(mockCTBorder);
when(mockTable.getCTTbl().getTblPr().getTblBorders().getRight()).thenReturn(mockCTBorder);
doNothing().when(mockCTBorder).setColor(anyString());
when(mockTable.getCTTbl().getTblPr().getTblW()).thenReturn(mockCTTblWidth);
doNothing().when(mockCTTblWidth).setType(Mockito.any());
doNothing().when(mockCTTblWidth).setW(Mockito.any());
when(mockDocument.createParagraph()).thenReturn(mockParagraph);
when(mockParagraph.createRun()).thenReturn(mockRun);
when(mockTable.getRow(anyInt())).thenReturn(mockRow);
when(mockRow.getCell(anyInt())).thenReturn(mockCell);
when(mockCell.addParagraph()).thenReturn(mockParagraph);
when(mockRow.createCell()).thenReturn(mockCell);
proffesionalSumaryService.populateDocumentWithProfileSkills(mockDocument,exportProfileDTO);
}
}
你知道测试这个类的更好方法吗?我将不胜感激.
Do you know a better way of testing this class? I would appreciate any help.
推荐答案
您的代码主要是与库的交互.它只包含很少的计算部分.此外，该代码创建了一个具有特定视觉外观的文档.
Your code is dominated by interactions with libraries. It contains only few computational parts. Moreover, the code creates a document that is meant to have a certain visual appearance.
将计算部分提取到单独的方法中并通过单元测试对其进行测试可能是有意义的，但即使这样也可能在这里过头了.但是，使用集成测试更好地测试交互(即，不是使用模拟进行隔离).当然，需要通过查看生成的文档来分析结果是否具有预期的视觉外观.
It may make sense to extract the computational parts into separate methods and test these via unit-testing, but even that could be overkill here. The interactions, however, are better tested with integration-testing (that is, not with isolation using mocks). And, certainly, whether the result has the intended visual appearance needs to be analysed by looking at the resulting documents.
