使用断言比较两个excel文件

Question

我使用 Visual Studio 创建一个自动化测试，该测试创建两个 Excel 工作表。作为最后的检查，我需要比较这两个excel表的内容并确保它们相等。有没有办法用断言来做到这一点？

像Assert.AreEqual(file1, file2);什么？

任何帮助或指导将不胜感激！

感谢Mangist对此的指导。我编写了以下内容来比较两个 Excel 文件：

public bool compareFiles(string filePath1, string filePath2)
    {
        bool result = false;
        Excel.Application excel = new Excel.Application();

        //Open files to compare
        Excel.Workbook workbook1 = excel.Workbooks.Open(filePath1);
        Excel.Workbook workbook2 = excel.Workbooks.Open(filePath2);

        //Open sheets to grab values from
        Excel.Worksheet worksheet1 = (Excel.Worksheet)workbook1.Sheets[1];
        Excel.Worksheet worksheet2 = (Excel.Worksheet)workbook2.Sheets[1];

        //Get the used range of cells
        Excel.Range range = worksheet2.UsedRange;
        int maxColumns = range.Columns.Count;
        int maxRows = range.Rows.Count;

        //Check that each cell matches
        for (int i = 1; i <= maxColumns; i++)
        {
            for (int j = 1; j <= maxRows; j++)
            {
                if (worksheet1.Cells[j, i].Value == worksheet2.Cells[j, i].Value)
                {
                    result = true;
                }
                else
                    result = false;
            }
        }


        //Close the workbooks
        GC.Collect();
        GC.WaitForPendingFinalizers();
        Marshal.ReleaseComObject(range);
        Marshal.ReleaseComObject(worksheet1);
        Marshal.ReleaseComObject(worksheet2);
        workbook1.Close();
        workbook2.Close();
        excel.Quit();
        Marshal.ReleaseComObject(excel);

        //Tell us if it is true or false
        return result;
    }

并使用断言来检查结果：

Assert.IsTrue(compareFiles(testFile, compareFile), "Output files do not match.");
