selenium中implicitly_wait对is_element_present()的影响.md

设置了默认等待时间是30sself.driver = webdriver.PhantomJS()self.driver.implicitly_wait(30)然后在测试时每次点击链接前会先去查找链接元

设置了默认等待时间是30s

self.driver = webdriver.PhantomJS()self.driver.implicitly_wait(30)

然后在测试时每次点击链接前会先去查找链接元素是不是存在:

def wait_for(self, content, timeout=10):        print("in wait_for: %s" % content)        for i in range(timeout):            try:                #print(datetime.datetime.now())                if self.is_element_present(By.LINK_TEXT, content): break                #print(datetime.datetime.now())            except: pass            time.sleep(1)        else:            print("time out")            self.fail("time out")

发现链接找不到时程序会等很久才退出, 经调试发现is_element_present是会等待的,等待的时间是implicitly_wait的设置值, 加起来就是40s了
