重写unittest

import unittest

    """ TestCase classes that want to be parametrized should
        inherit from this class.
    """
    def __init__(self, methodName='runTest', param=None):
        super(ParametrizedTestCase, self).__init__(methodName)
        self.param = param
    @staticmethod
    def parametrize(testcase_klass, param=None):
        """ Create a suite containing all tests taken from the given
            subclass, passing them the parameter 'param'.
        """
        testloader = unittest.TestLoader()

        suite = unittest.TestSuite()
        for name in testnames:
            suite.addTest(testcase_klass(name, param=param))

xlrd读取Excel数据

import xlrd

        '''获取测试数据
            参数：excelPath Excel文件路径

        data = xlrd.open_workbook(excelPath)  # 根据路径，找到excel文件
        table = data.sheet_by_name(sheetName)  # 打开excel文件中的哪一个sheet
        keys = table.row_values(0)  # 获取第一行作为key
        rowNum = table.nrows  # 获取总行数,从1开始数
        colNum = table.ncols  # 获取总列数,从1开始数
        if rowNum <= 1:
            print("数据文件：{0} Sheet名称：{1} 数据异常".format(excelPath, sheetName))
        else:
            r = []
            j = 1
            # 提取每一行的值
            for i in range(rowNum - 1):
                s = {}

                r.append(s)
                j += 1

测试脚本

from src.test.common.common import Common
from src.test.common.common import ParametrizedTestCase
import unittest


class Test(ParametrizedTestCase):

    def test_login(self):
        data = self.param
        print("执行用例：{0}".format(data))

if __name__ == '__main__':
    suite = unittest.TestSuite()
    allData = Common().excel_data("E:\PycharmProjects\WebTest\data\case\login.xlsx","login")
    for data in allData:
        suite.addTest(ParametrizedTestCase.parametrize(Test,param=data))
    unittest.TextTestRunner(verbosity=2).run(suite)

输出：

可能会存在的问题

1.执行时，发现data为None

问题原因：运行配置中，使用的是“Python 测试” 执行的程序

解决方法：改用“Python”执行即可
