Problem with finding element with Selenium and Xpath

Question

I have a problem that is very strange for me because the code that I wrote, I am quite sure should work!

Config Details

Chrome version: 80.0.3987.132

ChromeDrivers version: same as Chrome version 80 (80.0.3987.106)

OS: Windows 10

IDE: InteliJ

Programming language: Java API

TestURL: https://allegro.pl

I am currently testing , just for learning purpose, and so far everything worked. In general the basic approach to click a menu element is to use this code:

driver.findElement(By.xpath("//div[@data-box-name='Some Value']/div/ul/li[2]/a")).click();

Now I am in deeper menu category on this page: https://allegro.pl/kategoria/komputery and I want to click on "Drukarki i skanery" like this:

driver.findElement(By.xpath("//div[@data-box-name='Categories']/div/section/div[2]/ul/li[3]/a"))

I know this is good, because when I do right click on this element and select copy Xpath it gives me almost this same Xpath. It gives me this:

//*[@id="opbox-category-tree"]/section/div[2]/ul/li[3]/a

I have tried with this Xpath as well and it does not work as well. I attached screen so you may see how the code looks like.

Is it possible that this entry is too deep and I have to give some longer path to my element? Please any help would be appreciated, I am kind of stuck on that right now.

Answer 1

What's the problem then? Both xPaths seem functional. On the other hand, a good practice is to simplify it as much as possible, so it's readable for you in the future and for other people. The following xPath seems a bit more readable to me:

//div[@id="opbox-category-tree"]//a[text()="Drukarki i skanery"]

You don't need to write every element on the way down as in section/div[2]/ul/li[3]/a. Also, [2], [3] etc. are not a good practice, it might change easily in the future, making your xPath disfunctional.

EDIT based on discussion below:

The real problem is that the test flow is as follows:

Given  as a user I opened page "https://allegro.pl/"
When agreement window appears
Then close agreement window
And  choose department Elektronika
And  choose category Komputery
And choose printer categories and scanners

When choose category Komputery is executed, it opens the category "Komputery" on a new browser tab, so you'd need to switch to that new tab first, and then look for "Drukarki i skanery" menu link.
