一、自动化测试中，生成测试报告并邮件发送，发现生成的测试报告内容为空：

当时的代码结构是：

if __name__ == '__main__':

test_app = "./"

now_time = time.strftime("%Y_%m_%d_%H_%M_%S")

fp = open(test_app+"/report/reportdata/"+now_time+"result.html", 'wb')

runner = HTMLTestRunner(fp,

title="XX系统测试报告",

description="运行环境：windows 10, firefox")

discover = unittest.defaultTestLoader.discover(test_app+"/test_case", pattern='*_sta.py')

runner.run(discover)

file_path = get_new_file('./report/reportdata/')

print("发送文件的路径", file_path)

send_mail(file_path)

原因是，在打开文件fp后，未关闭，增加fp.close()

if __name__ == '__main__':

test_app = "./"

now_time = time.strftime("%Y_%m_%d_%H_%M_%S")

fp = open(test_app+"/report/reportdata/"+now_time+"result.html", 'wb')

runner = HTMLTestRunner(fp,

title="XX系统测试报告",

description="运行环境：windows 10, firefox")

discover = unittest.defaultTestLoader.discover(test_app+"/test_case", pattern='*_sta.py')

runner.run(discover)

file_path = get_new_file('./report/reportdata/')

print("发送文件的路径", file_path)

fp.close()

send_mail(file_path)

二、调整后，代码如下，结果如下
