每次我写入 excel 时，它都会用一个空白文件覆盖整个文件 - PUZZLED

Question

我正在尝试做的是 onTestFailure (TestNG) 我正在尝试将通过/失败写入指定列。在下面的代码中，我只是想做一个小测试来将 Fail 写入指定的单元格。但是发生的事情是，它没有将通过/失败写入指定的单元格，而是从字面上覆盖整个文件并擦除我的所有数据，我对为什么会发生这种情况感到困惑。我在这里看过并用谷歌搜索但找不到答案。以下是以下代码：

 @Override
public synchronized void onTestFailure(ITestResult tr){
    try {
        Workbook workbook = Workbook.getWorkbook(new File(testData), workbookSettings);
        WritableWorkbook wb = Workbook.createWorkbook(new File(testData), workbook);
        WritableSheet ws = wb.getSheet("OrderEditQA3");
        Label label = new Label(5,2, "Fail");
        ws.addCell(label);
        wb.write();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (BiffException b){
        System.out.print("Error!");
    } catch (WriteException we){
        System.out.print("");
    }
}

任何帮助将不胜感激。

下面是我用来将测试数据返回到 Dataprovider 的另一个类，我还从指定的工作表中加载我的所有元素。下面是代码

//获取所有测试数据的代码

protected static Object[][] loadTestData(String sheetName)throws BiffException, IOException{
    Sheet sheet = null;
    try{
        sheet = getWorkBook().getSheet(sheetName);
        rowCount = sheet.getRows();
        colCount = sheet.getColumns();
        data = new String[rowCount -1][colCount-1];
        int ci;
        int cj;
        ci=0;
        for(int i=1; i< rowCount; i++, ci++){
            cj=0;
            for(int j=1; j< colCount; j++, cj++){
                Cell cell = sheet.getCell(j,i);
                if(cell.getContents().isEmpty()){ continue;}
                System.out.print(cell.getContents() + "\n");
                data[ci][cj] = cell.getContents();
            }
        }
    }catch (IOException io){
        System.out.print(String.format("File: %s not found!", testData));
    }
    getWorkBook().close();
    return data;
}

//获取所有元素属性的代码：

@BeforeClass
protected static List<String> loadElements()throws BiffException, IOException {
    Sheet sheet = null;
    sheet = getWorkBook().getSheet("Elements");
    rowCount = sheet.getRows();
    colCount = sheet.getColumns();
    List<String> list = new ArrayList<>(rowCount);
    for (int i = 1; i < rowCount; i++) {
        for (int j = 0; j < colCount; j++) {
            Cell cell = sheet.getCell(j,i);
            if(cell.getContents().isEmpty()) {continue;}
            String cellContents = cell.getContents();
            list.add(cellContents);
            System.out.print(cell.getContents() + "\n");
        }
    }
    elements = list;
    getWorkBook().close();
    return list;
}

忘了那个讨厌的 close() 方法

@Override
public synchronized void onTestFailure(ITestResult tr){
    try {
        Workbook workbook = Workbook.getWorkbook(new File(testData), workbookSettings);
        WritableWorkbook wb = Workbook.createWorkbook(new File(testData), workbook);
        WritableSheet ws = wb.getSheet("OrderEditQA3");
        Label label = new Label(5,2, "Fail");
        ws.addCell(label);
        wb.write();
        wb.close();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (BiffException b){
        System.out.print("Error!");
    } catch (WriteException we){
        System.out.print("");
    }
}
