【第八章】参数化测试引入 paramunittest(类似ddt),优化脚本是否执行用例

• 参数化测试引入 paramunittest

　　引言:

　　　　上一章节我们讲到的是断言跟添加异常模块,这一章节我们讲的是如何进行参数化实现

• 新建demo

• 添加测试类,新增运行用例方法

• 新增testcase包
• 新建test_api_case.py

# @File : test_api_case

import unittest
import paramunittest
from common.testcase_data_utils import TestCaseDataUtils
from common.request_utils import RequestsUtils

testcase_data_lists = TestCaseDataUtils().convert_data_info_list()


@paramunittest.parametrized(
    *testcase_data_lists
)
class TestApiCase(paramunittest.ParametrizedTestCase):

    def setParameters(self, case_id, case_step):
        self.case_id = case_id
        self.case_step = case_step

    def test_api_case(self):
        test_result = RequestsUtils().request_steps(self.case_step)
        self.assertTrue(test_result["check_result"])


if __name__ == '__main__':
    unittest.main(verbosity=2)

• 优化excel是否执行用例

1. 将excel是否执行用例改成否
2. 在数据转换的时候判断如果为是的话执行,为否的话不执行

• 修改testcase_data_utils.py

import os
from common.excel_utils import ExcelUtils

current = os.path.dirname(os.path.abspath(__file__))
excel_file_path = os.path.join(current, '..', 'testcase_data', 'testcase_infos.xlsx')
excel_sheet_name = "Sheet1"


class TestCaseDataUtils:

    def __init__(self):
        self.ex = ExcelUtils(excel_file_path=excel_file_path,
                             sheet_name=excel_sheet_name)

    def convert_data_info_dict(self):
        """
        将测试数据转换成字典
        :param testcase_info:
        :return:
        """
        test_case_dict = {}
        for testcase in self.ex.get_all_excel_data():
            if testcase["用例执行"] == "是": # 新增代码
                test_case_dict.setdefault(testcase['测试用例编号'], []).append(testcase)
        return test_case_dict

    def convert_data_info_list(self):
        test_case_list = []
        for key, value in self.convert_data_info_dict().items():
            type_dict = {}
            type_dict["case_id"] = key
            type_dict["case_step"] = value
            test_case_list.append(type_dict)
        return test_case_list

if __name__ == '__main__':
    print(TestCaseDataUtils().convert_data_info_list())

• 总结

　　这一章节主要引入了paramunittest参数化模块,跟优化的是否执行用例的代码部分,下一章讲解引入测试报告模块
