存在元素时发生NoSuchElementException [英] NoSuchElementException when element is present

问题描述

这是我的代码:

     @return_to_home()
    def test_upvote(self):
        driver.find_element_by_id("com.ATG.World:id/fab").click()
        driver.implicitly_wait(timer)        
        driver.find_element_by_id("com.ATG.World:id/share_url_fab_clicked.").click()
        driver.find_element_by_id("com.ATG.World:id/tvSelectGroup").click()
        driver.find_element_by_id("com.ATG.World:id/tv_group_name").click()
        driver.find_element_by_id("com.ATG.World:id/ibCLose").click()
        driver.find_element_by_id("com.ATG.World:id/edtShareLink").send_keys("https://www.google.com")
        driver.implicitly_wait(timer)        
        driver.find_element_by_id("com.ATG.World:id/ivShareUrl").click()
        driver.find_element_by_id("com.ATG.World:id/tv_likes").is_enabled()        
        driver.find_element_by_id("com.ATG.World:id/tv_likes").click()
        verify_api("ws-upvote")        
        try:
            driver.find_element_by_id("com.ATG.World:id/post_details_back").click()  
            driver.implicitly_wait(timer)        
            driver.find_element_by_id("com.ATG.World:id/cross_fab_clicked").click()
        except:
            pass

    @return_to_home()
    def test_dislIke(self):
        driver.find_element_by_id("com.ATG.World:id/fab").click()
        driver.implicitly_wait(timer)        
        driver.find_element_by_id("com.ATG.World:id/share_url_fab_clicked.").click()
        driver.find_element_by_id("com.ATG.World:id/tvSelectGroup").click()
        driver.find_element_by_id("com.ATG.World:id/tv_group_name").click()
        driver.find_element_by_id("com.ATG.World:id/ibCLose").click()
        driver.find_element_by_id("com.ATG.World:id/edtShareLink").send_keys("https://www.google.com")
        driver.implicitly_wait(timer)        
        driver.find_element_by_id("com.ATG.World:id/ivShareUrl").click()
        driver.find_element_by_id("com.ATG.World:id/tv_unlikes").is_enabled()
        driver.find_element_by_id("com.ATG.World:id/tv_unlikes").click()      
        try:
            driver.find_element_by_id("com.ATG.World:id/post_details_back").click()            
            driver.find_element_by_id("com.ATG.World:id/touch_outside").click()            
            driver.find_element_by_id("com.ATG.World:id/cross_fab_clicked").click()
        except:
            pass

相同的代码有效，但不喜欢的方法无效 甚至在评论不同行之后

Same code is working but dislike method is not working Even after commenting unlike line

推荐答案

首先，当您使用find_element_by_id方法时，硒将通过使用[id="%s"]将值转换为css(％s是您提供的值).

First of all, when you use find_element_by_id method selenium will convert the value to css by using [id="%s"] (%s is the value you provided).

现在，您在错误行中提供的com.ATG.World:id/fab id不是有效的CSS.您必须使用\屏蔽所有特殊字符，如下所示.

Now that the com.ATG.World:id/fab id that you provided in the error line is not a valid css. You have to mask all the special chars with \ as shown below.

driver.find_element_by_id("com\.ATG\.World\:id\/fab").click()

下面是证据它是如何工作的.我更喜欢使用find_element_by_css_selector并提供如选项1或2所示的完整CSS.

Below is the evidence how it works. I would prefer using find_element_by_css_selector and provide the complete css as shown in either option 1 or 2.

选项1:

选项2:
