Question

我正在努力达到这个结果

| method | | passed | | datetime
| method | | passed | | datetime
| method | | passed | | datetime
| method | | passed | | datetime

要实现这一目标，我目前有一个课程XLWriter

class XLWriter:
    def __init__(self, file):
        self.workbook = load_workbook(file)
        self.worksheet = self.workbook['Sheet1']
        self.file = file

    def write(self, row):
        index = 0
        try:
            # func name, test passed, date
            values = [[inspect.stack()[0][3]], True, datetime.date]

            columns = [4, 6, 8]

            # 3 writes to perform
            while index < 2:
                cell = self.worksheet.cell(row=row, column=columns[index])
                cell.value = values[index]
                index += 1
        except:
            # function name, declare test failed, date
            values = [[inspect.stack()[0][3]], False, datetime.date]
            columns = [4, 6, 8]
            while index < 2:
                cell = self.worksheet.cell(row=row, column=columns[index])
                cell.value = values[index]
                index += 1

    def save(self):
        self.workbook.save(self.file)

从test.py调用此类时，如下所示

from xlwriter import XLWriter
xl = XLWriter('File.xlsx')

r = self.driver.current_url
self.assertEqual(r, url)
# write to row 14
xl.write(14)
xl.save()

我遇到了以下ValueError

ValueError: Cannot convert ['write'] to Excel

我确定这是一个小而愚蠢的东西，任何帮助都将不胜感激。

尝试将列表写入单元格时代码失败。

请更新您的代码，使列表“值”的第一个元素为inspect.stack（）[0] [3]，而不是[inspect.stack（）[0] [3]]。

更新的代码：

class XLWriter:
    def __init__(self, file):
        self.workbook = load_workbook(file)
        self.worksheet = self.workbook['Sheet1']
        self.file = file

    def write(self, row):
        index = 0
        try:
            # func name, test passed, date
            values = [inspect.stack()[0][3], True, datetime.date]

            columns = [4, 6, 8]

            # 3 writes to perform
            while index < 2:
                cell = self.worksheet.cell(row=row, column=columns[index])
                cell.value = values[index]
                index += 1
        except:
            # function name, declare test failed, date
            values = [inspect.stack()[0][3], False, datetime.date]
            columns = [4, 6, 8]
            while index < 2:
                cell = self.worksheet.cell(row=row, column=columns[index])
                cell.value = values[index]
                index += 1

    def save(self):
        self.workbook.save(self.file)
