感谢提供了这么多方法，已经解决问题啦

反正我试了好几个 HTMLTestRunner 文件，都能生成报告，但是报告都没有 print 的内容

我下了官方 python2 的改成 3 的，不行，然后又下了好几个也不行，你用 python3 么，有输出内容么，要是有，分享一个吧

脚本如下：

#! coding:utf-8
#!/usr/bin/python

@File: RA_Login.py

import unittest #Python 单元测试框架
from appium import webdriver # 导入 appium 库

# 用 unittest 编写测试脚本框架
class LoginTest(unittest.TestCase):

def setUp(self):

desired_caps['appPackage'] = 'com.yixin.itoumi'
desired_caps['appActivity'] = 'com.yixin.itoumi.module.login.SplashActivity'
#desired_caps['noReset'] = False
#desired_caps['unicodeKeboard'] = "True"
#desired_caps['resetKeyboard'] = 'True'

self.wd = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
self.wd.implicitly_wait(10)

return (x, y)

l = self.getSize()
self.wd.swipe(l[0] * 0.5, l[1] * 0.75, l[0] * 0.5, l[1] * 0.25, duration)

for i in range (0,4):
self.SwipeLeft(300)
