一、獲取測(cè)試用例

Excel用例分為兩部分
元素

獲取頁(yè)面元素信息：

def getPages(path):
    book = xlrd.open_workbook(path)  # 打開(kāi)要讀取的Excel
    sheet = book.sheet_by_index(0)
    rows = sheet.nrows  # sheet頁(yè)里面的行數(shù)
    webPages = []##存放webPage類(lèi)
    webpage = webPageClass()
    for i in range(1, rows):
        cells = sheet.row_values(i)
        # print(cells)
        if i == 1:
            webpage.pageName = cells[0]
        elif cells[0] != '':
            ##如果當(dāng)?shù)谝桓裼兄?，那么將上一個(gè)webpage對(duì)象加入到webpages集合中，并創(chuàng)建一個(gè)新的webpage類(lèi)
            webPages.append(webpage)
            webpage = webPageClass()

        if i == rows - 1:
            ##當(dāng)?shù)竭_(dá)最后一行時(shí)，將webpage對(duì)象添加到webpages中
