python——一些常用的方法类

测试的时候经常需要使用一些方法都整理放在一起，方便调用

首先一些基本的配置引入

 localReadConfig = readConfig.ReadConfig()
 proDir = readConfig.proDir
 log = Log.get_log()

 caseNo = 0

根据xls_name和sheet_name来读取数据

 def get_xls(xls_name, sheet_name):
     """
     get interface data from xls file
     :param xls_name:
     :param sheet_name:
     :return:
     """
     cls = []
     # get xls file's path
     xls_path = os.path.join(proDir, 'testFile', 'case', xls_name)
     # open xls file
     file = xlrd.open_workbook(xls_path)
     # get sheet by name
     sheet = file.sheet_by_name(sheet_name)
     # get one sheet's rows
     nrows = sheet.nrows
     for i in range(nrows):
         if sheet.row_values(i)[0] != u'case_name':
             cls.append(sheet.row_values(i))
     return cls

将结果写入到excel中

 def write_result_into_xls(xls_path, sheet, wb, result, row, col):
     sheet.write(row, col, result)
 　　 wb.save(xls_path)

 def write_results_into_xls(xls_name, sheet_name, results, col):
     xls_path = os.path.join(proDir, 'testFile', 'case', xls_name)
     rb = xlrd.open_workbook(xls_path)
     wb = copy.copy(rb)
     sheet = wb.get_sheet(sheet_name)
     for i in range(len(results)):
         write_result_into_xls(xls_path, sheet, wb, results[i], i+1, col)

正则表达式匹配

 用import.re导入正则表达式模块
 用re.complie()函数创建一个Regex对象（记得使用原始字符串）
 向Regex对象的search()方法传入想查找的字符串。它返回一个Match对象
 调用Macth对象的group()方法，返回实际匹配文本的字符串
