appium-循环执行一条用例，失败时停止执行

对于项目中一些难以复现的bug,手工操作比较耗时耗力，而且还不一定能够复现，如果知道操作步骤就可以用自动化来进行反复操作来复现该问题。

1.了解该问题的操作步骤

2.抓取日志

3.遇到问题时，抓取截图

4.复现问题后停止执行命令，并停止日志。

首先想到的是使用monkey,可以通过自定义monkey来模拟操作步骤，由于能力有限，不知道monkey如何断言，并且如果一直运行logcat抓取日志，日志又太多，无法准确定位，所以想到使用appium.

1.操作步骤，这里就不贴出了

2.抓取日志 （这里进行了封装）

class logcat:
　　　
#开启adb命令
    def start_logcat(self, name):     
        data = time.strftime("%Y-%m-%d", time.localtime(time.time()))
        # path = "../../report/log/" + data
        dir = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
        path = os.path.join(dir, 'report/' + name)

        type = '.txt'
        now = time.strftime("%Y-%m-%d-%H_%M_%S", time.localtime(time.time()))
        filename = ''

        if os.path.exists(path):
            filename = path + "\" + now + "_" + name + type
        else:
            os.makedirs(path)
            filename = path + "\" + now + "_" + name + type
        global logcat_file
        logcat_file = open(filename, 'w')
        logcmd = "adb logcat -v time"
        global poplog
        poplog = subprocess.Popen(logcmd, stdout=logcat_file, stderr=subprocess.PIPE)

# 结束adb命令
    def stop_logcat(self):
        logcat_file.close()
        poplog.terminate()

3. 遇到问题时截图

def take_screenShot(driver,dir, name):

    day = time.strftime("%Y-%m-%d", time.localtime(time.time()))
    fq = "../../report/" + dir    # 上上级目录   ../上级目录   ./当前目录
    # dir = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
    # fq = os.path.join(dir, 'report/log/' + day)
    # fq =os.getcwd()[:-4] +'screenShots\'+day    根据获取的路径，然后截取路径保存到自己想存放的目录下
    tm = time.strftime("%Y-%m-%d_%H_%M_%S", time.localtime(time.time()))
    type = '.png'
    filename = ""
    if os.path.exists(fq):
        filename = fq + "\" + tm + "_" + name + type
    else:
        os.makedirs(fq)
        filename = fq + "\" + tm + "_" + name + type
    # c = os.getcwd()
    # r"\".join(c.split("\"))     #此2行注销实现的功能为将路径中的替换为\
    driver.get_screenshot_as_file(filename)

    print(name + "图片保存成功"）

 4.循环该条用例

    def choose_case(self):
        for i in range(1, 10000):
            ClearAllTestReport()                             # 可能执行次数过多，这里每次都会清空日志
            print(u'第', i, u'执行用例')
            testunit = unittest.TestSuite()
            testunit.addTest(multi_run("test_cash"))
            runner = unittest.TextTestRunner()
            result = runner.run(testunit)                    #得到执行的结果
            if not result.wasSuccessful():　　　　　　　　　　　# 如果执行结果为fail,停止执行
                break
