Selenium Webdriver - Overview & Features

-

What is Selenium Webdriver?

 'Selenium Webdriver' is what world is talking about. Selenium Webdriver is web automation tool which is used for web functional testing. It supports different languages like Java, Python, C#, PHP, Ruby and Perl. WebDriver is now an official W3C Specification, and in-short, it is a method of interacting with a web browser. Previously, with Selenium RC, Selenium would operate with the browser by injecting JavaScript to interact with elements. With the adoption of WebDriver, browser manufacturers like Google, Mozilla, and Microsoft release their browser with the ability to be controlled by a hook, that Selenium can tap into. This hook enables Selenium to interact with the webbrowser in the same way that humans do.

Various Selenium Variants:
First of all I would like to tell you that there are different variants of Selenium, so don’t get confused.

 1. Selenium IDE - It’s a record and play tool, comes as plugin with Firefox only. No coding is required if you want to automate using this tool. But it can only be used for some very basic automation. As you cannot write your own logic or you won’t be able to put conditions or loops in your automation test script.

2. Selenium RC - RC stands for remote control. We have to write code using RC and it supports a number of languages. But it’s outdated now and there is no support available for RC.

3. Selenium Webdriver - Selenium Webdriver is web automation tool which can be used with different languages like Java, Python, C#, PHP, Ruby, Perl etc. It’s the successor of RC. Different architecture as what RC had (Not going in details).

4. Selenium Grid - Used for parallel execution of test cases (not an automation tool)

Features of Selenium Webdriver:
1. Opensource/Freeware: Selenium is free of cost. It means you do not have to buy any license like other softwares or do not have to pay to anyone for using Selenium for automation testing.
2. Web Functional Framework: Selenium can only be used for automation testing of web applications/website. It is a functional testing tool so we can only automate functional test cases.
3. Multi-Language Support: It is one of the major benefits of Webdriver. Selenium Webdriver supports many languages like Java, Python, PHP, C#, Ruby, Perl etc. So, it provides the flexibility to automation test engineers to automate test cases using any one language that they are comfortable.
4. Cross OS Support: Selenium supports multiple OS like, Windows, Linux, Unix, Mac. So if you have written webdriver automation code using windows platform, then same automation code could be used on other OS platforms like Unix, Linux, Mac.
5. Cross-Browser Compatibility Testing: Selenium Webdriver supports almost every browser like Chrome, FF, Safari, Opera, IE and their versions. You can execute same automation scripts on different browsers for compatibility testing.
6. Cross Device Testing: Appium, which is a mobile automation tool is actually build on the top of Selenium Webdriver apis. In simple words Appium is another form of Webdriver to  e used for automation testing of mobile  applications.
7. Huge Community Support: There is a huge community support for Selenium. A lot of tech professionals are contributing in building Selenium as the best automation tool.
8. Integrated with Multiple Frameworks/Tools: Selenium Webdriver can be integrated with various frameworks and tools like, Maven, Ant for compiling source code, with unit testing frameworks like TestNG for application testing and reporting and with Jenkins for Continuous Integration or Continuous Delivery, automated build and deployment.
9. Integration Support with other Automation Tools: It also gives the flexibility to integrate Java or Python modules, other automation tools like Sikuli, AutoIT for your automation needs.

How To Handle Dynamic Xpaths (Web Table) in Selenium WebDriver

-
In this selenium webdriver post, we will learn how to handle dynamic web table. There might occur some scenarios where every time a page loads with different number of rows and columns or different columns for each row.

For that, we have to put two for loops,
1. first loop will iterate all the rows and
2. second loop inside it will iterate the columns of each row


publicclassDynamicTable{ WebDriver driver =new FirefoxDriver();@BeforeTestpublicvoidsetup()throws Exception { driver.manage().window().maximize(); driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); driver.get("https://www.techlistic.com/p/demo-selenium-practice.html");}@AfterTestpublicvoidtearDown()throws Exception { driver.quit();}@Testpublicvoidtest_Dynamic_Webtable(){// Locate table WebElement mytable = driver.findElement(By.xpath(".//*[@id='post']/div[1]/table/tbody"));// Locate rows of table and save locators of each row in a list List rows_table = mytable.findEl…

In this tutorial we will learn to take full screenshot and partial screenshot. In automation we capture the screenshots for reference. To capture screenshot in Selenium 'TakeScreenshot' interface is used.




Take Screenshot Command:
/************************************ * Capture Screenshot * ************************************ *//* Create object of File class of Java * And capture screenshot using getScreenshotAs() method of Webdriver * Set Output type of screenshot taken as 'File'*/File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); /* Use FileUtils class of Java * Call it's copyFile method * Copy screenshot file to a location with some name and extension you want*/FileUtils.copyFile(screenshot,new File("D:\\screenshot.jpg"));



How to Take Partial Screenshot:

Sometimes we don't want to take screenshot of the full screen. Reasons might be, full size images would last in huge memory storage for image directory or…

Selenium WebDriver - Browser and Navigation Commands

-
Browser commands are the starting point of your Selenium Webdriver script. These commands used to launch browser, maximize it, open URL to be tested and other navigation commands.
1. Browser Commands i. Set Path of browser/driver executable:
This would be the first line of your webdriver script. You have to download the browser executable file for the browser you are using and set path of the driver executbale to system property.Like for firefox you have to download geckodriver.exe and place in your project. Similarly for other browsers you have to download their browser/driver executables.Download Driver Executables link - https://www.seleniumhq.org/download/Below is an example for Firefox.


// Set Path of driver executable String driver_executable_path = "./src/com/techlistic/utils/geckodriver.exe"; System.setProperty("webdriver.gecko.driver", driver_executable_path);

ii. Launch Broswer: // Launch Browser - Creating a Firefox instance WebDriver driver = new FirefoxDri…

Automation Framework Building 1st step - Implementing Code Re-usablility

-

In this post, you will learn kind of coding pattern which is very helpful in maintaining our automation code. This post is written insight to help beginners. We'll learn that instead of writing a linear script, we should create page (action) methods which in general contain actions which we are going to perform on our web software. 

Let's say, we have a login functionality in our software and we have to automate it. In that case we'll create a method named login and write the commands like, entering username, password and click login in that method. Now we can use that method wherever we need it in other test cases as well. Benefits of using action methods are:

Code Re-usabilityBetter maintainability of codeSharing below a sample script, in which I'm entering data in a web form using action methods:





You can also place these action methods in some other class like Common.java. And if you want to re-use any of the methods in your Selenium script, just create the object Comm…
