You can use the data URI scheme to load some HTML with Selenium:

WebDriver driver = new FirefoxDriver();
driver.get("data:text/html;charset=utf-8," + htmlString);

May be you need to use the Actions with name attribute in Xpath. In your XPath use it -

"/*[name()='svg']/*[name()='SVG OBJECT']"

Then try the following code snippet -

WebElement svgObj = driver.findElement(By.xpath(XPATH));
Actions actionBuilder = new Actions(driver);
actionBuilder.click(svgObj).build().perform();

The WebDriver interface does not contain the getScreenshotAs() method, because it is possible to have a webdriver unable of taking screenshots - for example the in-memory drivers that don't render the page at all, like HtmlUnitDriver.

In order to have the method, the driver must implement the TakesScreenshot interface which makes it capable to ... well ... take screenshots.

Therefore, you must tell the program somehow that you want to take a screenshot and that you are absolutely sure you can do so. That's what the (TakesScreenshot)driver part is for. In Java, it's called casting and it literally translates to "I know that this driver instance is able to take a screenshot, please cast it to TakesScreenshot type."

If your cast succeeds, everything is fine and the driver object will be cast at run-time to an instance of TakesScreenshot. If your cast fails, however, you'll get a ClassCastExcepion at run-time.

Some examples:

// We already know this is ok, because FirefoxDriver implements (IS-A) TakesScreenshot.
WebDriver driver = new FirefoxDriver();
TakesScreenshot screenshottingDriver = (TakesScreenshot)driver;

// This will fail at run-time, because HtmlUnitDriver does not implement TakesScreenshot;
WebDriver driver = new HtmlUnitDriver();
TakesScreenshot screenshottingDriver = (TakesScreenshot)driver;

// You can use the `instanceof` operator to check:
if (driver instanceof TakesScreenshot) {
    // we can be sure we can take screenshots, the cast will be safe
    ((TakesScreenshot)driver).getScreenshotAs(...);
}

The best way for you is to take java (which is officially deprecated and it suggests you use openjdk image) and install node in it.

So, start with

FROM openjdk:latest

This will use the latest openjdk image, which is 8u151 at this time. Then install node and other dependencies you might need:

RUN apt-get install -y curl \
  && curl -sL https://deb.nodesource.com/setup_9.x | bash - \
  && apt-get install -y nodejs \
  && curl -L https://www.npmjs.com/install.sh | sh

You might want to install things like grunt afterwards, so this might come in handy as well.

RUN npm install -g grunt grunt-cli

In total you will get the following Dockerfile:

FROM openjdk:latest

RUN apt-get install -y curl \
  && curl -sL https://deb.nodesource.com/setup_9.x | bash - \
  && apt-get install -y nodejs \
  && curl -L https://www.npmjs.com/install.sh | sh \
RUN npm install -g grunt grunt-cli

You may clone the Dockerfile from my gitlab repo here

While working with Selenium v3.11.x, GeckoDriver v0.20.0 and Firefox Quantum v59.0.2 there are different option to invoke a new/existing Firefox Profile

If you are looking to use a new Firefox Profile on every run of your Test Execution you can use the following code block :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
FirefoxOptions options = new FirefoxOptions();
options.setProfile(new FirefoxProfile());
WebDriver driver = new FirefoxDriver(options);
driver.get("https://www.google.com");

If you are looking to use an existing Firefox Profile on every run of your Test Execution first you have to create a Firefox Profile manually following the instructions at Creating a new Firefox profile on Windows.

Now you have 2 ways to invoke the Firefox Profile you have created as follows :

You can use the FirefoxOptions class to invoke the existing Firefox Profile and you can use the following code block :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
ProfilesIni profile = new ProfilesIni();
FirefoxProfile testprofile = profile.getProfile("debanjan");
FirefoxOptions opt = new FirefoxOptions();
opt.setProfile(testprofile);
WebDriver driver =  new FirefoxDriver(opt);
driver.get("https://www.google.com");

You can also use the DesiredCapabilities class to set the existing Firefox Profile and later merge within an instance of FirefoxOptions and you can use the following code block :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
ProfilesIni profile = new ProfilesIni();
FirefoxProfile testprofile = profile.getProfile("debanjan");
DesiredCapabilities dc = DesiredCapabilities.firefox();
dc.setCapability(FirefoxDriver.PROFILE, testprofile);
FirefoxOptions opt = new FirefoxOptions();
opt.merge(dc);
WebDriver driver =  new FirefoxDriver(opt);
driver.get("https://www.google.com");

24 Things You Might Be Doing Wrong In Website Testing!

Website testing sounds simple, yet is complex, based on the nature of the website. Testing a single webpage is simple and can be done manually. But with the nature of web applications becoming complex day by day, especially in the current age of robust, dynamic single page applications that are developed using Angular or React, the complexity of testing is also increasing.

Loadable Components In Selenium: Make Your Test Robust For Slow Loading Web Pages

Being in automation testing for the last 10 years I have faced a lot of problems. Recently I was working on a selenium automation project and in that project everything was going fine until I faced a most common but difficult problem. How to make sure that my selenium automation testing work fine even for slow loading web pages. A quick google and browsing through forums highlighted that this is a problem that testers are facing for many past years. If you too have faced it then yes, this article is there to help you from my personal experience.

LambdaTest Launches API For Selenium Automation!

At the start of the year, we launched our LambdaTest online Selenium automation grid that can help you perform cross browser compatibility testing on a scalable on-cloud selenium infrastructure. We have seen a tremendous response for the platform and we are humbled by the positive feedbacks.

Machine Learning for Automation Testing

The goals we are trying to achieve here by using Machine Learning for automation in testing are to dynamically write new test cases based on user interactions by data-mining their logs and their behavior on the application / service for which tests are to be written, live validation so that in case if an object is modified or removed or some other change like “modification in spelling” such as done by most of the IDE’s in the form of Intelli-sense like Visual Studio or Eclipse.
