Selenium with Java –
Why Java?

Java is one of the enterprised programming languages around the world. Syntactically not too simple, yet powerful because of its features.

So, learning Selenium in combination with java is never a bad choice.

 

Why Java with Selenium?

A)As Java is popular in the current era, learning Selenium with Java is a very good decision to start your career as an Automation Test Engineer. There is no wastage of time spent learning Java.

 

What are Web Applications?

Applications that basically run on the browser are called Web applications.

Ex: Facebook, Amazon, Flipkart, Instagram, and many more

Now let’s see how to install Java!!!

Go to the oracle website and download JDK(Java development Kit)

Now let’s see how to install Selenium:

Visit the website selenium.dev

 

• Click on the downloads option, download the latest version of selenium standalone server(i.e nothing but a JAR(Java Archive File).
• We need to download Driver Software, because Selenium doesn’t interact directly with browser, so we have different driver softwares, so our selenium can speak with different browsers.
• Selenium can communicate with Chrome browser using chrome driver.
• Selenium can communicate with Firefox browsers using gecko drivers.
• Selenium can communicate with Internet Explorer using iedriver.
• Driver softwares can be downloaded from the official website selenium.dev

Now let’s see some of the most popular and frequently used methods in our Selenium Scripts:

Creating an object for the ChromeDriver class will launch the Chrome Browser from your system.

Ex:ChromeDriver driver = new ChromeDriver();

 

get() = This method is used to navigate to any website

Ex: driver.get(“https://www.facebook.com”)

 

quit() = This method is used to quit the Browser

Ex: driver. quit()

 

closee() = This method is used to closee the current tab on your browser.

Ex: driver.close()

 

getCurrentUrl() = This method is used to get the URL associated with that particular webpage. 

Ex: driver.getCurrentUrl()

 

getTitle() = This method is used to get the Title associated with that webpage.

Ex: driver.getTitle()

 

sendKeys() = This method is used to enter the data into an input box.

Ex: driver.send_keys(“Welcome123”)

 

click() = This method is used to click on a particular button available on the webpage.

Ex: input.click()

 

clear() = This method is used to clear the data available in the input box.

Ex: input.clear()

Q)What are the various frameworks available in selenium?

•   Data Driven Framework
•   Keyword Driven Framework

Locators:

Now let’s see what role locators play in selenium!

If Selenium wants to perform any kind of action on any of the webelements like Entering the text in an input box which is created using input tag, click on a button, getting the relevant information, selecting the drop-down from the webpage , click on refresh button, and many more, first selenium has to get the power to identify that web element, once the element is identified then selenium can easily perform the action on that web element. So, to identify that particular element for selenium

We use the concept of locators.

Various locators available in Selenium are:

We can identify the various web elements available on the webpage using the following locators:

 Id: Which uses findElement(By.id()) method.

Name: which used findElement(By.name()) method.

className: which uses findElement(By.className()) method.

Tag Name: which used findElement(By.tagName()) method.

Link text: which uses findElement(By.linkText()) method.

Partial link text: which uses findElement(By.partialLinkText()) method.

Xpath: which uses findElement(By.xpath()) method.

CSS Selector: which uses findElement(By.css()) method.

NOTE: All the above locators are used to identify only one element at a time.

If we want to identify multiple elements, instead of using findElement we have to use findElements, and the rest of everything will be the same.
