Can not get file path from resource folder - Java

2021-01-16 11:23 Bastian imported from Stackoverflow

I try to automate a page that I have. In the page I need to upload a PDF file. The problem is that I want selenium via java will get the file from the resource of the project and not hard coded. (since some have windows and some mac and some ubonto so the solution is to get the path dynamically).

I manually hard coded I enter the path it worked and return the path, however to let java return the path it crash. this is my code:

  /******* test *******/
    public  void testFileUpload() throws Exception {
        WebDriver deiver2 = getWebDriver();
      

        Thread.sleep(3000);
        deiver2.switchTo()
                .activeElement();
        deiver2.findElement(By.xpath("//input[@type='file']"))
        .sendKeys(
                "X:\\project\\src\\test\\resources\\TAX12.pdf");

        ClassLoader classLoader = getClass().getClassLoader();
        String path = classLoader.getResource("TAX12.pdf").getPath();
        System.out.println("\n\n path is  " + path);

        System.out.println("END");

    }

I want in the send keys to send the file, the exists however it is not worked. get null exception

the file exists in the folder and worked if manually set the path, but not locate the file if I want it to do it by himself (for win / mac / linux etc)

Leetcode, getting TLE after memoization, Palindrome Partitioning -2

Question -> https://leetcode.com/problems/palindrome-partitioning-ii/

Leetcode palindrome partitioning problem, getting TLE after memoization, provided my recursive approach as well in my question. Please correct me in this approach only.

The recursive approach will obviously give TLE, then I tried memoization approach, still getting tle even after memoizing . what else can I do to improve its complexity.

Is there a way to convert data collected from Opencv's facial landmarks and translate the points to a 3d model

I have successfully started my journey in Opencv as part of my machine learning adventure, one topic I find interesting is facial landmarks which are able to trace out 64 or more points on a humans face, I would like to know if I can transfer the data that Opencv is collecting from those landmarks on to a 3d human face model to mimic whatever the individual is doing, similar to Apple's Animoji, any library or API in Java or C++ that could perform this action would be greatly appreciated.

Adopting code from Oddsportal URL to current & Next Page

I have a code that scrapes

https://www.oddsportal.com/soccer/england/premier-league/

odds and event data.

I want to adopt the same to get all data for "today" which is reflected at

https://www.oddsportal.com/matches/soccer/

and 'tomorrow' is

https://www.oddsportal.com/matches/soccer/20210309/

which is essentially url/today+1

My current code that works is:

browser = webdriver.Chrome()
browser.get("https://www.oddsportal.com/soccer/england/premier-league/")

df = pd.read_html(browser.page_source, header=0)[0]

dateList = []
gameList = []
home_odds = []
draw_odds = []
away_odds = []

for row in df.itertuples():
    if not isinstance(row[1], str):
        continue
    elif ':' not in row[1]:
        date = row[1].split('-')[0]
        continue
    time = row[1]
    dateList.append(date)
    gameList.append(row[2])
    home_odds.append(row[4])
    draw_odds.append(row[5])
    away_odds.append(row[6])

result = pd.DataFrame({'date': dateList,
                       'game': gameList,
                       'Home': home_odds,
                       'Draw': draw_odds,
                       'Away': away_odds})

Because the datelist[] is different to the links e.g. Algeria»Ligue 1 I am getting an error

NameError: name 'date' is not defined

How can I adopt the same to

https://www.oddsportal.com/matches/soccer/

and for tomorrow ?

Headless Chrome driver unable to fetch Instagram page in python Selenium driver

I tried to login and scrape a few details from my Instagram page in Python. I wanna do it in the headless mode because I'm going to deploy it in Heroku. So when I try to login using this code in the headless Chrome driver, the Instagram login page is not fetched. I have provided the screenshot also.

def login_insta(driver,username,password):
    driver.get("https://www.instagram.com/accounts/login")
    time.sleep(5)
    driver.save_screenshot('scrnsh.png')
    driver.find_element_by_xpath(
        "//input[@name='username']").send_keys(username)
    driver.find_element_by_xpath(
        "//input[@name='password']").send_keys(password)

    driver.find_element_by_xpath("//button/div[text()='Log In']").click()
    print("Logged in")


options = Options()
PATH = r"C:\Users\pcname\Downloads\chromedriver"
options.add_argument("--headless")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--no-sandbox")
options.add_argument('--disable-gpu')
driver = webdriver.Chrome(executable_path=PATH, chrome_options=options)

login_insta(driver,"name","pass")

Screenshot

The screenshot said "Error Please wait a few minutes before you try again" This error doesn't occur with the headlesss Firefox driver, I don't how to add Firefox buildpacks in Heroku. I have recent Chrome driver version. Please help me solve this issue.

Or if you can suggest buildpacks for Firefox for Heroku, and the steps to add them, it would be very helpful. Thank you!

How to set browser width and height in Selenium WebDriver?
I try to set bowser size to a certain dimensions using:
```
browser = webdriver.Chrome()
browser.set_window_position(100, 100)
browser.set_window_size(1024, 768)
```
but it seems webdriver ignores Y parameter - window is correctly shifted 100 points from the left, but the 100 points from the top are ignored. The most annoying is that Y dimension is ignored too - window height is set to 2035 points (4K monitor height minus taskbar) (Linux x86_64, KF5, Python 3.9.1, Selenium 3.141.0). I've seen solution with just maximizing the window, but having window 6 time larger than necessary seems no OK. Currently I create virtual desktop of appropriate size and then maximise window on it, but I don't think its sustainable solution.
Getting "Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR" while running Python Selenium test scripts
I am running the test scripts with chrome browser using python selenium test scripts.
```
            chromedriver = '.\\chromedriver.exe'

            options = webdriver.ChromeOptions()
            options.add_argument('--headless')
            options.add_argument('--incognito')
            options.add_argument('--disable-gpu')
            options.add_argument("--no-sandbox")
            options.add_argument('--ignore-certificate-errors')
            options.add_argument('window-size=1920x1080')
```
Cannot share the whole code but I have used sleep, implicit and explicit waits to slow down the webpage loads but still I am getting different failures in each time. The least errors I have seen is 6 out of 120 test cases and there is only 1 of them is a real failure. I thought about AJAX failure so I have added the waits mentioned above but still cannot trust the test scripts.

I am taking the screenshots of the failures and my only option would be to run the failed test cases one more time to see if they would pass.

Any suggestions are welcomed. Thank you for your time.
Selenium ChromeDriver Action and SendKeys don´t press the button
I have a problem with my SeleniumDriver and it drives me crazy. I almost tried every solution on stackoverflow..

My simple goal is to send a key to the browser, but not to an element. My key is "mediaTrackNext" and can be found at
```
Windows.Forms.Keys.MediaNextTrack
```
I tried almost any solution:
```
Dim actions As Actions = New Actions(TestBot)
actions.SendKeys(Windows.Forms.Keys.MediaNextTrack).Perform()
```
or
```
TestBot.FindElement(By.XPath("/html/body")).SendKeys(Windows.Forms.Keys.MediaNextTrack)
```
or
```
Dim actions As Actions = New Actions(TestBot)
actions.SendKeys(TestBot.FindElement(By.XPath("//body")), Keys.F12).Perform()
```
I can´t even send keys like F12 to open the developers console, nothing happens.. F5 doesn´t work as well. And yes, I tried a few Tags and xpaths, but no tag seem to work.

Is there another way? I am so stuck right now..

Thank you. Best regards, xored
