安装ddt

下载地址：https://pypi.python.org/pypi/ddt/1.1.0

class ExcelUtil(object):
    def __init__(self, excelPath, sheetName):
        try:
            self.data = xlrd.open_workbook(excelPath)
        except Exception as e:
            print(str(e))
        self.table = self.data.sheet_by_name(sheetName)

        # get titles
        self.row = self.table.row_values(0)

        # get rows number
        self.rowNum = self.table.nrows

        # get columns number
        self.colNum = self.table.ncols

        # the current column
        self.curRowNo = 1

    def next(self):
        r = []
        while self.hasNext():
            s = {}
            col = self.table.row_values(self.curRowNo)
            i = self.colNum
            for x in range(i):
                s[self.row[x]] = col[x]
            r.append(s)
            self.curRowNo += 1
        return r

    def hasNext(self):
        if self.rowNum == 0 or self.rowNum <= self.curRowNo:
            return False
        else:
            return True

在unittest框架中使用ddt进行迭代,@ddt.data接收一个可迭代的类型，来判断执行的次数，excel.next()返回的是一个数组

import unittest
import ddt
import ExcelUtil
excel = ExcelUtil("excelPath", 'Sheet1')

@ddt.ddt
class DataTest(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        print('start')

    @classmethod
    def tearDownClass(cls):
        print('stop')

    @ddt.data(*excel.next())
    def testLogin(self, data):
        print(data['username'], data['password'])

if __name__ == "__main__":
    suite = unittest.TestLoader().loadTestsFromTestCase(DataTest)
    unittest.TextTestRunner(verbosity=2).run(suite)

excel表格如下：

最后的输出结果为：
