python中unittest單元測試框架-加載測試用例、運行測試用例、生成測試報告-通過discover加載某個文件夾下的所有用例

import os
import unittest
import HTMLTestRunnerNew

# 1、初始化testloader
testloader = unittest.TestLoader()

# 2、查找測試用例,加載
dir = os.path.dirname(os.path.abspath(__file__))
case_dir = os.path.join(dir, 'test_cases')

suite = testloader.discover(case_dir)


# 創建存放測試報告的文件夾-report
report_path = os.path.join(dir, 'report')
if not os.path.exists(report_path):
    os.mkdir(report_path)

file_path = os.path.join(report_path, 'test_result.html')

with open(file_path, "wb+") as f:
    # 初始化運行期， 是以普通文本生成測試報告 TextTestRunner
    runner = HTMLTestRunnerNew.HTMLTestRunner(stream=f, title='API測試報告', description='執行用例詳情', tester='奔奔')
    # 運行測試用例
    runner.run(suite)
