How to use getCanonicalCapabilities method of org.openqa.selenium.ie.InternetExplorerDriverInfo class

When you want to wait for element to be not present, instead of presenceOfElementLocated use presenceOfAllElementsLocatedBy:

wait.until(ExpectedConditions.not(ExpectedConditions.presenceOfAllElementsLocatedBy(By.xpath("//div[contains(text(),'Loading...')]"))));

It will wait until there are no elements on the page that fit the locator.

As far as I know, there are 3 ways:

1. Implicit wait: (It's applicable for all elements on the page)

   driver.manage().timeouts().implicitlyWait(A_GIVEN_NUMBER, TimeUnit.SECONDS);

2. Explicit wait: (Applicable for a particular element)

   WebDriverWait.until(CONDITION_THAT_FINDS_AN_ELEMENT);

More specific code is as below:

WebDriverWait wait = new WebDriverWait(driver, 40);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("someid")));

1. Using Thread:

   Thread.sleep(NUMBER_OF_MILLIS);

You're trying to get an attribute value, so instead of getText() use getAttribute() :

driver.findElement(By.xpath("//meta[@name='description']"))
      .getAttribute("content")

Easiest solution would be, add the below lines in surefire plugin.

<suiteXmlFiles>
    <!-- pass testng.xml files as argument from command line -->
    <suiteXmlFile>${suiteXmlFile}</suiteXmlFile>
</suiteXmlFiles>

And run your xml file as below,

mvn clean test -Dsurefire.suiteXmlFiles=/path/to/testng.xml

This error message...

org.openqa.selenium.SessionNotCreatedException: session not created exception from tab crashed (Session info: chrome=65.0.3325.181) (Driver info: chromedriver=2.37.544315 (730aa6a5fdba159ac9f4c1e8cbc59bf1b5ce12b7),platform=Windows NT 6.1.7601 SP1 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 2.50 seconds Build info: version: '3.11.0', revision: 'e59cfb3', time: '2018-03-11T20:26:55.152Z' System info: host: 'USNBDFV9K12', ip: '10.23.4.80', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_131' Driver info: driver.version: ChromeDriver

The error stack trace clearly shows your ChromeDriver binary details are not getting detected back as in :

Driver info: driver.version: ChromeDriver

Though your chromedriver=2.37.544315 and Chrome: 65.0.3325.181 are compatible your main issue is java.version: '1.8.0_131' which is ancient.

Solution

• Upgrade JDK to recent levels JDK 8u162
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a system Reboot.
• Execute your @Test.

from tab crashed

from tab crashed was WIP(Work In Progress) with the Chromium Team for quite some time now which relates to Linux attempting to always use /dev/shm for non-executable memory. Here are the references :

• Linux: Chrome/Chromium SIGBUS/Aw, Snap! on small /dev/shm
• Chrome crashes/fails to load when /dev/shm is too small, and location can't be overridden
• As per Comment61#Issue 736452 the fix seems to be have landed with Chrome v65.0.3299.6

Hence you may need to bump up to Chrome v65.0.3299.6 or later.

You can easily accomplish this task with CSS.

The formula is:

element[attribute='attribute-value']

So if you have,

<a href="mysite.com"></a>

You can find it using:

By.cssSelector("a[href='mysite.com']");

this works using any attribute possible.

This page here gives good information on how to formulate effective css selectors, and matching their attributes: http://ddavison.io/css/2014/02/18/effective-css-selectors.html

You could write a user extension (or just some JavaScript in a storeEval etc) that tests that window.onbeforeunload is set, and then replaces it with null before continuing on from the page. Ugly, but ought to get you off the page.

    String base = driver.getWindowHandle();

    Set <String> set = driver.getWindowHandles();

    set.remove(base);
    assert set.size()==1;

    driver.switchTo().window(set.toArray(new String[0]));

    driver.close();
    driver.switchTo().window(base);

This works for me...

Since I posted this question, I've found a few different solutions to this problem. I'm posting them here for reference so that this question is useful to others:

When drag and drop in Selenium failed to work for HTML5, a defect was entered against Selenium and some people commented on the defect with suggested Javascript work around solutions:

JQuery/HTML5 Solution

http://code.google.com/p/selenium/issues/detail?id=3604#c9

This is a ruby-based solution, which could be translated into Java, C#, or any other language supported by Selenium. It requires JQuery to be on the page, as is clear from many of the comments from other users trying to use this solution, and it seems this only works for HTML5 pages:

The workaround we put together is working for us. It's been a life saver for testing our Ember.js app.

attached is the latest version of what we are using...

this is what we have in our test_helper:

  def drag_and_drop(source,target)

    js_filepath=File.dirname(__FILE__)+"/drag_and_drop_helper.js"
    js_file= File.new(js_filepath,"r")
    java_script=""

    while (line=js_file.gets)
      java_script+=line
    end

    js_file.close

    @driver.execute_script(java_script+"$('#{source}').simulateDragDrop({ dropTarget: '#{target}'});")

    rescue Exception => e
      puts "ERROR :" + e.to_s

  end

The source code for the referenced Javascript drag and drop simulation is posted here:

https://gist.github.com/rcorreia/2362544

(function( $ ) {
    $.fn.simulateDragDrop = function(options) {
        return this.each(function() {
            new $.simulateDragDrop(this, options);
        });
    };
    $.simulateDragDrop = function(elem, options) {
        this.options = options;
        this.simulateEvent(elem, options);
    };
    $.extend($.simulateDragDrop.prototype, {
        simulateEvent: function(elem, options) {
            /*Simulating drag start*/
            var type = 'dragstart';
            var event = this.createEvent(type);
            this.dispatchEvent(elem, type, event);

            /*Simulating drop*/
            type = 'drop';
            var dropEvent = this.createEvent(type, {});
            dropEvent.dataTransfer = event.dataTransfer;
            this.dispatchEvent($(options.dropTarget)[0], type, dropEvent);

            /*Simulating drag end*/
            type = 'dragend';
            var dragEndEvent = this.createEvent(type, {});
            dragEndEvent.dataTransfer = event.dataTransfer;
            this.dispatchEvent(elem, type, dragEndEvent);
        },
        createEvent: function(type) {
            var event = document.createEvent("CustomEvent");
            event.initCustomEvent(type, true, true, null);
            event.dataTransfer = {
                data: {
                },
                setData: function(type, val){
                    this.data[type] = val;
                },
                getData: function(type){
                    return this.data[type];
                }
            };
            return event;
        },
        dispatchEvent: function(elem, type, event) {
            if(elem.dispatchEvent) {
                elem.dispatchEvent(event);
            }else if( elem.fireEvent ) {
                elem.fireEvent("on"+type, event);
            }
        }
    });
})(jQuery);

Another user posted additional code when it didn't work completely for him, along with some instructions for injecting JQuery into the page:

http://code.google.com/p/selenium/issues/detail?id=3604#c25

We had trouble with the original drag_and_drop_helper.js posted as a workaround for this issue. The workaround is 99% correct, but I needed to modify the workaround to include the dropTarget in the options propagated via the 'coord' object in simulateDrag.

i.e. I need to change:

  coord = { clientX: x, clientY: y }

to:

coord = { clientX: x, clientY: y , dropTarget: options.dropTarget || undefined }

Also, a note for those following the example usage, if the app under test does not already alias the jQuery function to $, you will need to spell-out jQuery:

i.e., after injecting the drag and drop helper onto the page, we have a method that accepts jQuery selectors to use the simulated drag and drop functions (Java):

/**
 * Drag and drop via the JQuery-based drag and drop helper -- the helper
 * must have been injected onto the page prior to calling this method.
 *
 * @param dragSourceJQuerySelector a JQuery-style selector that identifies the source element to drag;
 * <em>will be passed directly to jQuery(), perform all quoting yourself</em>
 * @param dropTargetJQuerySelector a JQuery-style selector that identifies the target element to drop the source onto;
 * <em>will be passed directly to jQuery(), perform all quoting yourself</em>
 */
protected void dragAndDropViaJQueryHelper(String dragSourceJQuerySelector, String dropTargetJQuerySelector) {
    String javascript =
        "var dropTarget = jQuery(" + dropTargetJQuerySelector + ");" +
        "\n" +
        "jQuery("+ dragSourceJQuerySelector + ").simulate('drag', { dropTarget: dropTarget });";

    getLogger().info("executing javascript:\n" + javascript);
    this.executeScript(javascript);
    getLogger().info("executed drag-n-drop action via javascript");
}

Another, non-jQuery solution

http://ynot408.wordpress.com/2011/09/22/drag-and-drop-using-selenium-webdriver/

Javascript based drag and drop which works across browsers.

Mouse move stopped working after version 2.3 while using RemoteWebDriver in selenium. The below function drags element 1 to element 2 position and releases the mouse down.

public void dragdrop(By ByFrom, By ByTo) {
    WebElement LocatorFrom = driver.findElement(ByFrom);
    WebElement LocatorTo = driver.findElement(ByTo);
    String xto=Integer.toString(LocatorTo.getLocation().x);
    String yto=Integer.toString(LocatorTo.getLocation().y);
    ((JavascriptExecutor)driver).executeScript("function simulate(f,c,d,e){var b,a=null;for(b in eventMatchers)if(eventMatchers[b].test(c)){a=b;break}if(!a)return!1;document.createEvent?(b=document.createEvent(a),a==\"HTMLEvents\"?b.initEvent(c,!0,!0):b.initMouseEvent(c,!0,!0,document.defaultView,0,d,e,d,e,!1,!1,!1,!1,0,null),f.dispatchEvent(b)):(a=document.createEventObject(),a.detail=0,a.screenX=d,a.screenY=e,a.clientX=d,a.clientY=e,a.ctrlKey=!1,a.altKey=!1,a.shiftKey=!1,a.metaKey=!1,a.button=1,f.fireEvent(\"on\"+c,a));return!0} var eventMatchers={HTMLEvents:/^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,MouseEvents:/^(?:click|dblclick|mouse(?:down|up|over|move|out))$/}; " +
    "simulate(arguments[0],\"mousedown\",0,0); simulate(arguments[0],\"mousemove\",arguments[1],arguments[2]); simulate(arguments[0],\"mouseup\",arguments[1],arguments[2]); ",
    LocatorFrom,xto,yto);
}
