Tests slow because High cpu using Headless chrome with version 87

2020-11-23 14:02 Roy imported from Stackoverflow

When I run tests without using headless chrome, the tests take on average 40-50 seconds. When I run the tests using headless chrome it takes a lot longer (190 seconds on average). I'm using chromedrivermanager which runs on 87.0.4280.20.

The browser class without using headless:

 private String baseUrl = ConfigHandler.getPropertyValue("url");
private WebDriver driver;

public Browser() {
    WebDriverManager.chromedriver().setup();
    Map<String, Object> prefs = new HashMap<>();
    ChromeOptions chromeOptions = new ChromeOptions();

    String FilesPath = System.getProperty("user.dir") + File.separator + SeleniumUtilities.getDownloadsPath();
    prefs.put("download.default_directory", FilesPath);
    chromeOptions.setExperimentalOption("prefs", prefs);
    this.driver = new ChromeDriver(chromeOptions);
    this.driver.manage().window().maximize();
}

Browser class using headless chrome:

 private String baseUrl = ConfigHandler.getPropertyValue("url");
private WebDriver driver;

public Browser() {
    WebDriverManager.chromedriver().setup();
    Map<String, Object> prefs = new HashMap<>();
    ChromeOptions chromeOptions = new ChromeOptions();

        System.out.println("working on server");
        chromeOptions.addArguments("--window-size=1400,900");
        chromeOptions.addArguments("--headless");
        chromeOptions.addArguments("--no-proxy-server");
        chromeOptions.addArguments("--proxy-server='direct://'");
        chromeOptions.addArguments("--proxy-bypass-list=*");
    

    String FilesPath = System.getProperty("user.dir") + File.separator + SeleniumUtilities.getDownloadsPath();
    prefs.put("download.default_directory", FilesPath);
    chromeOptions.setExperimentalOption("prefs", prefs);

    this.driver = new ChromeDriver(chromeOptions);

}

Any Ideas?

EDIT: I noticed in headless chrome the cpu get really high, unlike without using headless. Why the cpu so high when running in headless?

  • Can not find file that is in resource folder - java

    I have a question regarding file handling. I automate a page using selenium, and I need to upload a file in this page. I want to put the file in resource folder and read it's path in the test (since many OS and path will be different to any computer WIN/MAC).

    I put the file manually in the resource folder, and it put it in:

    X:\Project_11_01_2021\src\test\resources

    when I used the ClassLoader and try to find the file it not found it, I saw that if I manually put it in this path it find it, found.

    X:\Project_11_01_2021\out\test\resources

    the problem is that I am using git and if I add to the resources it upload to git and every one will get the change, and when I put in out\test\resources it is not displayed in the source tree to commit to git. is their a way that classLoader will search in the first location? and not in the second?

    [enter image description here][path that worked]

    [enter image description here][when here not worked]

    /******* test *******/

    public  void entertax() throws Exception {

    System.out.println("\n\n path is  " + path);

  • Can not get file path from resource folder - Java

    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)

  • How to preserve @page margin but with a sidebar

    I've been trying to generate a dynamic invoice using Handlebars and Puppeteer. Now the problem is that I need to display a 'sidebar' so to speak in my invoice template. However, I also need @page margin so that overflowing content gets wrapped to a new page with enough margin. See image below for clarification:

    I set up a github repo with example code you can check out here (instructions to run project in read.me).

    sidebar cut off

    How can I preserve the margin added with @page, but also have a sidebar that goes fully from top to bottom?

  • Why puppeteer page.goto() hangs?

    I'm running puppeteer in an alpine-chrome container with sandboxing, everything is done exactly as the docs suggest. And I've created a whole bunch of different puppeteer-fueled servers.

    I'm launching Puppeteer without any arguments, except headless: false.

    Why is await page.goto() method so problematic? It keeps giving me all kinds of non-sensical problems.

    I'm always doing this:

    await page.goto('https://my-url.com/something', {
  waitUntil: 'networkidle2',
  timeout: 0
})

    Right now it just randomly hangs. Nothing happens, code execution just stops there. All I see is that CPU utilization hits the roof and then down to slightly-elevated levels, comparing to the properly-ongoing execution. 90% of time the goto doesn't elevate CPU utilization at all. Same page, same server, hangs randomly within the same script execution.

    Why is this hapening? Do I have to put setTimeout and try-catch statements all over my code around each page.goto() method? It feels like I'm using puppeteer fundamentally incorrect, because this behaviour doesn't make sense.

    Sorry for vague question, I don't understand what kind of information would be helpful here.

  • SElinux blocking Google-Chrome (headless)

    Good evening all,

    Last month I commissioned a new OracleLinux server, and installed the latest Chrome version on it.

    The project currently, is a small website which needs to generate a PDF report. First, I create a HTML file with the entire content (it's only a header image, a table, and a footer - nothing too fancy). Then, PHP issues this to generate the PDF file, after which it's downloaded by the user.

    $output = shell_exec('/usr/bin/xvfb-run /usr/bin/google-chrome --no-sandbox --headless --disable-gpu --no-margins --print-to-pdf-no-header --print-to-pdf=/location/to/pdffile.pdf /location/to/htmlfile.html ');

    This works great when I perform the action on the commandline (copy & paste the command). However, when the PHP script executes the action, the following errors are generated and shown in the browser;

    [0110/224510.775219:ERROR:file_path_watcher_linux.cc(71)] Failed to read /proc/sys/fs/inotify/max_user_watches

    Trying to find anything useless on the internet on those errors, failed. So I looked further in /var/log/messages

    It appears that Chrome needs all kinds of permissions to print a HTML into a PDF. SElinux is prohibiting Chrome certain actions. Now I'm wondering ... What is the solution? Can I simply execute the commands suggested by SElinux in the errors below, or is it better to do something else? If so, what? After spending the entire weekend on the internet, I found no real information regarding this.
