环境:

问题:test_a 用例执行完之后,在执行 test_b 之前就报错

用例代码如下:

import time
import unittest

from appium.webdriver.common.touch_action import TouchAction
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.support.ui import WebDriverWait
from waiqing_testcase import DRIVER
from waiqing_testcase.screenshot import take_screenshot
from selenium.webdriver.support import expected_conditions as EC
from common import *


class MyAndroidTest(unittest.TestCase):

    def setUp(self):
        global driver
        driver = DRIVER.MyDriver.get_driver()

    def tearDown(self):
        driver.quit()

    def test_a(self):
          ...
    def test_b(self):
          ...

if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(MyAndroidTest) 
    unittest.TextTestRunner(verbosity=2).run(suite)

appium driver 代码:

# -*- coding:utf-8 -*-
from appium import webdriver
import threading


class MyDriver:
    driver = None
    mutex = threading.Lock()
    desired_caps = {}
    desired_caps['deviceName'] = 'Android Emulator'
    desired_caps['platformName'] = 'Android'
    desired_caps['platformVersion'] = '4.2'
    desired_caps['appPackage'] = 'com.xbcx.waiqing'
    desired_caps['appActivity'] = 'com.xbcx.waiqing.activity.StartActivity'

    def __init__(self):
        pass

    @staticmethod
    def get_driver():
        if MyDriver.driver is None:
            MyDriver.mutex.acquire()
            if MyDriver.driver is None:
                MyDriver.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
            else:
                return MyDriver.driver
            MyDriver.mutex.release()
        else:
             print "you have been created a session"
        return MyDriver.driver

pychram 中的错误日志:问题好像出在 driver.quit() 这里,但给出的错误 WebDriverException: Message: ,也没有显示到底是因为什么导致的报错

日志显示出错的地方
info: [debug] Responding to client with success:
{"status":0,"value":... }返回的给 client 的 value 的值是一串乱码

到这里为止,我不明白到底是哪里出错,为什么会返回乱码?应该怎么改?

第一次在 testerhome 上发帖,表达不清楚的地方,望大家见谅!
